A pressure tank is a critical component in many domestic, agricultural, commercial, and industrial water supply systems. Although it does not move water by itself, it works with a pump to stabilize pressure, reduce unnecessary starts and stops, improve operating comfort, and protect the complete pumping installation from excessive cycling. The NVT Series Vertical Pressure Tank for Pump is designed for these purposes, combining a replaceable membrane, carbon steel construction, practical vertical installation, and a selection of pressure ratings for different pumping applications.
The NVT Series is available in three principal capacities: NVT60L, NVT80L, and NVT100L. The models are manufactured with a carbon steel flange and are designed for working temperatures appropriate for commonly used membrane materials, including butyl and EPDM. Depending on the selected configuration, the tank can support maximum working pressures of 6, 8, 10, or 16 bar. Its vertical format makes efficient use of floor space while providing a straightforward solution for pressure boosting, water supply, irrigation, and pump-control systems.
This article explains the design, specifications, operating principles, manufacturing strengths, installation considerations, maintenance requirements, and application value of the NVT Series. It also examines how the tank can provide practical advantages compared with basic fixed-membrane or poorly matched pressure vessels used in similar installations.
NVT Series Vertical Pressure Tank for Pump
A pressure tank is a vessel that stores a quantity of pressurized water so that a pump does not need to start every time a small amount of water is used. Inside the tank, water is separated from compressed air or gas by a flexible membrane. When the pump operates, water enters the tank and compresses the air on the other side of the membrane. When a tap, sprinkler, or appliance requires water, the compressed air pushes the stored water into the system.
This arrangement creates a reserve of pressurized water and allows the pump to remain stopped during periods of low or intermittent demand. In a typical automatic booster system, the pressure tank works with a pressure switch, electronic controller, check valve, pressure gauge, and pump. The tank absorbs part of the demand variation, helping the control system maintain more stable pressure.
The term “vertical” refers to the installation orientation. A vertical tank stands upright on its base, with the water connection normally positioned at the lower section. This arrangement provides a relatively small floor footprint compared with a horizontal tank of similar volume. It is especially useful in pump rooms, utility spaces, plant rooms, agricultural installations, and domestic water supply areas where floor space must be used efficiently.
The NVT Series is a replaceable membrane pressure tank. This means the internal membrane can be removed and replaced when necessary, rather than requiring the complete pressure vessel to be discarded after membrane wear. This construction can improve serviceability, reduce long-term maintenance costs, and extend the useful life of the tank body.
The NVT Series Vertical Pressure Tank is categorized as a carbon steel pressure tank. Its principal structural material provides the mechanical strength needed for pressurized water storage, while the internal membrane separates the water from the air chamber. The carbon steel flange provides a firm connection between the tank body and the water-side assembly.
The supplied product information identifies the following principal features:
Replaceable membrane construction.
Carbon steel flange.
Working temperature suitability for butyl and EPDM membranes.
Multiple maximum pressure options, including 6, 8, 10, and 16 bar.
Vertical installation for efficient space utilization.
Three listed capacities: 60 liters, 80 liters, and 100 liters.
Precharge pressure in the range of 1.8 to 2.0 bar for the listed models.
One-inch connector size for the listed configurations.
The NVT60L, NVT80L, and NVT100L models share a number of standard features, but they differ in diameter, height, and packing volume. This provides system designers and installers with a practical choice between water storage capacity and available installation space.
The following table summarizes the technical information supplied for the NVT Series. Maximum pressure is shown according to the available pressure configurations. The dimensions and connector details refer to the listed models.
| Model | Maximum Pressure Options | Diameter | Height | Precharge Pressure | Connector | Packing Volume |
| NVT60L | 6, 8, 10, or 16 bar | 380 mm | 728 mm | 1.8–2.0 bar | 1 inch | 0.1126 CBM |
| NVT80L | 6, 8, 10, or 16 bar | 450 mm | 680 mm | 1.8–2.0 bar | 1 inch | 0.1481 CBM |
| NVT100L | 6, 8, 10, or 16 bar | 450 mm | 765 mm | 1.8–2.0 bar | 1 inch | 0.1650 CBM |
The available pressure options should be selected according to the operating pressure of the complete water system. A tank rated for a particular maximum pressure must not be installed in a system where the actual pressure, including possible surge or abnormal operating conditions, exceeds that rating. Correct selection should take account of pump shut-off pressure, pressure-switch settings, static head, water hammer, thermal expansion, and any applicable local safety requirements.
The product information lists butyl and EPDM membrane operating temperatures from -20°C to 99°C. It also lists natural rubber from 0°C to 77°C in the broader specification. The shorter product summary refers to a range of -10°C to 99°C for butyl and EPDM. Because these figures differ, the final operating range should be confirmed with the supplier for the exact membrane material, production configuration, and application before purchase.
The membrane is one of the most important parts of a pressure tank. It forms the barrier between stored water and the compressed air chamber. If the membrane is poorly designed, incompatible with the water, or difficult to replace, the service life and practical value of the tank can be reduced.
The replaceable membrane design of the NVT Series offers an important maintenance advantage. Over time, a membrane can experience repeated flexing, pressure changes, temperature exposure, and contact with water containing minerals or treatment chemicals. A replaceable construction allows technicians to renew the flexible internal component while retaining the main steel vessel, provided that the vessel remains structurally sound and meets inspection requirements.
This approach can be more economical than replacing an entire tank. It may also reduce waste and shorten service interruptions. For commercial users, agricultural operators, building managers, and pump distributors, serviceability is an important factor because a tank that can be repaired efficiently is easier to support throughout its operating life.
The membrane material should be chosen according to the fluid, temperature, and application. Butyl is widely used in pressure tank applications because of its flexibility and gas-retention characteristics. EPDM can be suitable for many water applications and offers useful resistance properties. Natural rubber is listed as another option with a lower stated temperature range. The correct membrane should always be selected based on the actual water quality, temperature, regulatory requirements, and intended use.
For potable water installations, users should confirm that the selected membrane and all wetted components comply with the relevant drinking-water regulations in the destination market. The general tank specification alone should not be treated as confirmation of certification for every country or application.
The NVT Series uses a carbon steel flange. A flange is not simply a connection detail; it is a load-bearing and sealing component that must remain stable under repeated pressure changes. It joins the tank body and water-side assembly and supports the connection between the pressure vessel and the pump system.
Carbon steel is commonly selected for pressure vessels because it offers useful mechanical strength, manufacturing flexibility, and cost efficiency. When formed, welded, coated, and inspected correctly, it can provide a durable foundation for pressure storage. The material is also widely understood by manufacturers, installers, and service technicians, making it easier to integrate into established production and maintenance processes.
The value of the flange depends on the complete manufacturing process. Proper forming, welding, surface preparation, dimensional control, sealing-surface accuracy, and pressure testing are all important. A strong material alone is not enough. The connection must remain aligned, the seal must seat correctly, and the assembly must be protected against corrosion appropriate to the installation environment.
For this reason, buyers should consider the manufacturer’s production controls, inspection procedures, and after-sales support when evaluating a pressure tank. These factors distinguish a professionally produced pressure vessel from a basic low-cost product with limited quality documentation.
When a pump starts, it supplies water to the building, irrigation network, or process system. Once the immediate demand is satisfied, the remaining flow enters the pressure tank. As water fills the tank, the membrane expands into the air chamber and compresses the air. The pressure in the water system rises until the pump control reaches its stop setting.
When water is later consumed, the compressed air pushes water out of the tank. The system can supply a limited amount of water without starting the pump. When the pressure falls to the start setting, the pump restarts and restores the reserve.
The useful water volume delivered between pump stop and pump start is known as drawdown. It is not equal to the tank’s total geometric volume. Drawdown depends on the tank capacity, precharge pressure, pump start and stop pressures, water temperature, membrane condition, and system design.
A correctly selected tank can reduce pump cycling. Frequent starts place stress on the pump motor, electrical contacts, seals, bearings, and control equipment. By supplying small and moderate demands from stored water, the pressure tank enables longer intervals between starts. This may improve system stability and help extend the service life of the pump and controls.
The tank can also reduce pressure fluctuations. Without sufficient storage, a pump may react too quickly to minor changes in demand. This can create an uncomfortable pulsating flow in domestic systems or unstable pressure in irrigation and commercial installations. The NVT Series provides a buffer between demand changes and pump operation.
The NVT Series offers several practical advantages over basic pressure tanks that use non-replaceable internal components or lack a suitable range of pressure configurations.
A replaceable membrane can lower lifecycle costs and simplify maintenance. If the membrane becomes worn while the tank body remains usable, the technician may replace the membrane rather than replacing the complete vessel. This is especially valuable in locations where equipment replacement is expensive, transport is difficult, or downtime affects production.
The availability of 6, 8, 10, and 16 bar configurations allows the tank to be matched more closely to different pump systems. A wider selection helps avoid the common problem of using one general-purpose tank across applications with substantially different pressure requirements.
The upright design uses a relatively narrow floor area. The NVT60L has a listed diameter of 380 mm, while the NVT80L and NVT100L have a listed diameter of 450 mm. This format may be useful where a horizontal tank would interfere with pipework, access paths, or other equipment.
The listed models use a one-inch connector. Standard connection sizing can simplify system integration and reduce the need for unusual adaptors. Nevertheless, the installer should verify the actual fitting type, thread standard, gasket requirements, and local piping arrangement before installation.
The availability of butyl and EPDM membrane options enables the tank to be adapted to a wider range of water supply conditions. The choice should be made according to temperature, water chemistry, hygiene requirements, and the specific application rather than by price alone.
The 60-liter, 80-liter, and 100-liter options allow the designer to balance reserve volume, available space, packaging, and pump output. A small domestic booster system may require a different tank size from an irrigation pump or commercial water supply installation.
Choosing the appropriate NVT model requires more than matching the tank’s nominal volume to the pump nameplate. The designer should examine demand pattern, pump capacity, pressure settings, installation space, pipe size, and required reserve volume.
The NVT60L is the smallest listed model in the series. It has a 380 mm diameter and a 728 mm height. Its smaller diameter can be useful in narrow technical rooms or compact pump cabinets. It may be suitable for domestic booster systems, small agricultural installations, garden irrigation, and applications with moderate intermittent water demand.
Although it has the smallest nominal capacity in the listed range, the NVT60L can still provide meaningful cycling reduction when correctly matched to the pump and control settings. Its suitability depends on the required drawdown rather than nominal volume alone.
The NVT80L provides an intermediate capacity. Its listed diameter is 450 mm and its height is 680 mm. Compared with the NVT60L, it has a larger diameter but a shorter height. This geometry may be useful where overhead clearance is limited but sufficient floor width is available.
The NVT80L can be considered for medium-duty domestic water supply, small commercial booster sets, agricultural irrigation zones, and systems where demand varies throughout the day. It provides a practical compromise between reserve water volume and installation requirements.
The NVT100L is the largest listed model and has a 450 mm diameter with a 765 mm height. It offers the greatest nominal reserve among the three models. This makes it appropriate for systems that experience longer periods of moderate demand or that require additional buffering to reduce pump starts.
The NVT100L may be useful in larger domestic installations, commercial buildings, irrigation systems, workshops, and equipment packages where the pump would otherwise cycle frequently. The tank should still be selected according to calculated system demand and pressure settings.
Taizhou Edwin Electric Co., Ltd., operating under the Edwin Pump name, was founded in 2008. The company is described as an integrated manufacturing enterprise with activities covering independent research and development, mass production, and global export. Its broader product portfolio includes deep well pumps, submersible pumps, domestic booster pumps, circulation pumps, solar water pumps, intelligent booster pumps, and related water treatment peripheral products.
This broader product background is relevant to the NVT Series because pressure tanks are most effective when selected as part of a complete pumping solution. A manufacturer experienced in different pump types can better understand the relationship between pump flow, pressure, control logic, piping, and storage volume.
The company’s stated manufacturing model combines product development with mass production. This combination can support consistent design reproduction, repeatable component sourcing, and clearer product standardization. For international buyers, repeatability is important because replacement units and future orders should maintain compatible dimensions and performance characteristics.
The company also operates related import and export organizations established to support procurement planning, order tracking, cross-border delivery, and foreign trade services. This structure is useful for overseas customers purchasing tanks together with pumps or other system components. Coordinated procurement can simplify documentation, packaging, production scheduling, and shipment management.
Since 2018, the company has invested in new energy and intelligent technology, including solar water pumps and intelligent booster pumps. Although the NVT Series is a mechanical pressure tank, it can serve as a useful hydraulic component in systems that include modern electronic pump controls. A pressure tank can complement intelligent control by providing a stable reserve and reducing the need for rapid pump response to every small demand.
A reliable pressure tank depends on a controlled sequence of production operations. The following process areas are important when manufacturing a carbon steel replaceable-membrane tank.
Steel sheets, formed parts, flanges, connectors, and other components should be sourced and prepared according to approved specifications. Material identification and dimensional checks help maintain consistent wall thickness, flange fit, and vessel geometry. Appropriate storage also reduces the risk of corrosion or deformation before fabrication.
The tank body must be formed into a geometry that can withstand internal pressure and repeated pressure fluctuations. Welding must be performed with controlled parameters and suitable procedures. Joint preparation, heat input, penetration, alignment, and post-weld inspection all influence the reliability of the vessel.
In pressure equipment, weld quality is particularly important because a small defect can become more significant under repeated loading. A professional manufacturing process should include visual inspection and, where required by the product standard or application, additional non-destructive or pressure-related checks.
The carbon steel flange must be accurately positioned and securely joined to the tank assembly. Dimensional accuracy affects membrane installation, connector alignment, gasket compression, and the ability to connect the tank to external pipework. Poor alignment can create installation stress and leakage risk.
Carbon steel requires appropriate protection against corrosion. Surface cleaning, preparation, coating, and curing should be controlled according to the selected finish and intended environment. The exterior coating must be capable of resisting normal handling, storage, moisture, and installation conditions.
For outdoor or humid installations, buyers should confirm whether additional protective measures are recommended. The tank should be installed where it is protected from flooding, standing water, aggressive chemicals, and direct mechanical impact.
The membrane should be produced from a compatible elastomer with controlled thickness, flexibility, and dimensional stability. The connection area must fit securely with the flange and sealing components. Inspection should identify pinholes, tears, uneven molding, contamination, or dimensional defects.
Because the membrane is a moving component, quality consistency is essential. It repeatedly flexes as the tank fills and empties. A properly designed membrane should distribute stress as evenly as possible and avoid sharp folds or unnecessary abrasion during operation.
Pressure testing helps verify the integrity of the tank body, flange, connector, and seals. Leak testing is also necessary because even a small leak can cause the tank to lose pressure, reduce drawdown, and increase pump cycling. Testing procedures should be performed using controlled equipment and according to the applicable product requirements.
Before shipment, each tank should be checked for model identification, dimensions, connector condition, coating quality, membrane configuration, precharge setting, and packaging security. The listed packing volumes are 0.1126 CBM for the NVT60L, 0.1481 CBM for the NVT80L, and 0.1650 CBM for the NVT100L.
Proper packaging is important because pressure tanks can be damaged by impact, abrasion, or incorrect stacking during international transport. Protection around the connector, flange, base, and coated surfaces can reduce the risk of damage before installation.
In houses, apartments, and small residential buildings, the NVT Series can provide stored water and reduce pump starts caused by short activities such as hand washing, toilet flushing, or briefly opening a tap. A pressure tank can also make automatic booster systems feel smoother and more stable.
Irrigation systems often experience changing demand as valves open and close or different watering zones operate. The tank can buffer these changes and help reduce pump cycling. The selected model should be matched to the pump’s flow and the irrigation control strategy.
Garden pumps may operate intermittently with sprinklers, hose reels, or automatic watering controls. A compact pressure tank can support more convenient automatic operation and reduce the need for the pump to start for every brief water draw.
Small offices, workshops, shops, restaurants, and service buildings may benefit from a pressure tank as part of a booster set. It can help maintain stable water delivery during variable demand and reduce unnecessary mechanical and electrical cycling.
Pressure tanks may be used in local water supply packages, utility stations, and small distribution systems. In these applications, the tank should be selected and installed in accordance with the engineering design, applicable pressure-vessel requirements, and local authority rules.
Some water systems associated with heating, cooling, or circulation equipment require pressure stabilization. The temperature range and membrane material must be confirmed carefully before using the tank in an HVAC-related application. The NVT Series should only be used where its materials and pressure rating are suitable for the actual fluid and temperature.
Solar pumping systems often experience changing available power because of cloud cover, time of day, and battery or controller conditions. A pressure tank can provide hydraulic storage that complements the electrical control system. It does not replace a solar controller or battery, but it can help provide water availability during short demand events and reduce rapid pump response.
The tank should be installed by qualified personnel familiar with pressurized water systems. Before installation, confirm the model, pressure rating, membrane type, connector size, precharge pressure, and physical dimensions.
The tank should stand on a stable, level surface capable of supporting the vessel when filled with water. The installation area should provide adequate clearance for pipe connection, inspection, membrane replacement, pressure checking, and safe maintenance. The upright vessel should not be allowed to lean or rest on unsupported pipework.
A suitable isolation valve may be installed so that the tank can be removed or serviced without draining the entire system. A drain arrangement can also make maintenance easier. Depending on the system design, a pressure gauge, pressure relief device, check valve, and pressure switch or electronic controller may be required.
The tank should be connected without excessive force. Pipework must be properly supported so that the connector and flange are not subjected to bending loads. Thread sealant or gasket selection should be compatible with the connection and the water system.
Never exceed the tank’s specified maximum pressure. The pressure relief arrangement should be selected and positioned in accordance with the system design and applicable regulations. The tank should also be protected from freezing, excessive heat, corrosive atmosphere, accidental impact, and exposure to fluids that could damage the coating or membrane.
The listed precharge pressure for the NVT models is 1.8 to 2.0 bar. Precharge is the air-side pressure measured when the water side has been isolated and depressurized. It is not normally measured while the tank is full of water or while the pump is operating.
Correct precharge adjustment is essential. If the precharge is too low, the membrane may be compressed excessively and the tank may provide poor drawdown. If the precharge is too high, the tank may accept too little water before the pump stops, reducing its ability to prevent cycling.
The correct setting depends on the pressure-switch or controller settings and the manufacturer’s installation guidance. As a general engineering principle, precharge is often set slightly below the pump-start pressure, but the exact difference should be confirmed for the specific system. Local regulations, controller instructions, and application requirements should take priority over general rules.
To check precharge, the pump should be switched off, the tank isolated if possible, and the water side fully depressurized. A calibrated pressure gauge should then be used at the air valve. If adjustment is required, air should be added or released gradually. After adjustment, the system should be restored and checked for leakage and correct pump operation.
Routine inspection can help preserve the performance of the NVT Series. The external coating should be checked for corrosion, impact damage, blistering, or flaking. The connector and flange area should be inspected for leakage. Unusual pump cycling, unstable pressure, or loss of stored water may indicate a precharge problem, membrane issue, leaking check valve, or incorrect control setting.
Precharge should be checked periodically, especially after the first period of operation, after maintenance, or when system behavior changes. The inspection interval depends on operating conditions, water quality, pressure fluctuations, and the importance of the installation.
If water escapes from the air valve, the internal membrane may have failed or the valve assembly may require attention. The tank should then be isolated and inspected by qualified personnel. Do not disassemble a pressurized tank. The water side and air side must be fully depressurized before any membrane or flange service is attempted.
When a membrane is replaced, the technician should use the correct replacement part for the exact tank model and material configuration. Sealing surfaces should be cleaned and inspected, fasteners should be tightened evenly, and the assembly should be checked for leakage before returning to service.
For international buyers, the value of a pressure tank includes more than the physical product. Consistent communication, accurate order processing, appropriate packaging, documentation, and shipment coordination can have a significant effect on the total purchasing experience.
Taizhou Edwin Electric Co., Ltd. presents itself as a manufacturer and exporter serving customers across global markets. Its related organizations support procurement planning, order tracking, cross-border delivery, and foreign trade services. This can be useful for importers, distributors, pump wholesalers, engineering contractors, and original equipment buyers who need coordinated sourcing.
The company’s product range also allows buyers to combine pressure tanks with pumps and other water-system products. A single-source procurement strategy may simplify technical communication and reduce the risk of mismatched components. Buyers can discuss pump performance, control settings, tank capacity, connector requirements, membrane selection, and shipping arrangements with one coordinated supplier.
For large or repeated orders, customers should request the applicable product drawings, pressure documentation, membrane details, packaging information, inspection records, and destination-market compliance documents. These materials help the buyer evaluate whether the selected configuration is appropriate for the intended project.
The NVT Series is designed around a straightforward but valuable principle: reliable pump operation depends on managing demand variation. A pump that starts and stops too frequently may experience unnecessary stress, while a system without sufficient pressure storage may deliver unstable water pressure.
By combining vertical installation, replaceable membrane construction, carbon steel flange design, several pressure options, and three capacity choices, the NVT Series provides flexibility for different system layouts. Its dimensions are also clearly defined, which helps engineers and installers plan the pump room, cabinet, pipework, and maintenance access before delivery.
The series is particularly attractive for users who consider lifecycle serviceability important. The possibility of replacing the membrane can reduce the cost and disruption associated with future maintenance. The selection of butyl or EPDM configurations can also support more careful material matching than a single-material, one-size-fits-all pressure tank.
Its advantages are strongest when the tank is correctly sized, the precharge is properly adjusted, the operating pressure remains within the rated limit, and the complete installation is professionally designed. No pressure tank can compensate for an incorrectly selected pump, blocked pipework, poor electrical control, inadequate relief protection, or improper maintenance.
Before ordering an NVT Series tank, buyers should confirm the following points:
Required nominal capacity: 60, 80, or 100 liters.
Required maximum pressure: 6, 8, 10, or 16 bar.
Required membrane material: butyl, EPDM, or another approved configuration.
Actual operating temperature and fluid characteristics.
Whether the application involves potable water, irrigation, industrial water, heating water, or another fluid.
Available installation space, including diameter, height, connection clearance, and service access.
Required connector type and local pipe-thread standard.
Required precharge pressure and compatible pump-control settings.
Applicable safety, pressure-vessel, and drinking-water regulations.
Required certificates, test records, drawings, spare membranes, and installation instructions.
Packaging, loading quantity, shipping method, and export documentation.
It is also advisable to provide the supplier with pump flow, pump maximum pressure, start and stop settings, expected water demand, and the number of daily operating cycles. This information allows the tank to be evaluated as part of a complete system rather than as an isolated product.
The main purpose is to store pressurized water and reduce the number of pump starts. It also helps stabilize pressure and provides a reserve of water for small or intermittent demands.
It means the internal flexible membrane can be removed and replaced when necessary, provided that the tank body and other components remain suitable for continued service. This can reduce maintenance cost compared with replacing an entire non-serviceable tank.
The listed models are NVT60L, NVT80L, and NVT100L. They have nominal capacities of 60, 80, and 100 liters respectively.
The technical data lists maximum pressure options of 6, 8, 10, and 16 bar. The correct option must be selected according to the complete system’s maximum operating pressure and applicable safety requirements.
The NVT60L has a listed diameter of 380 mm and a height of 728 mm.
The NVT80L has a listed diameter of 450 mm and a height of 680 mm.
The NVT100L has a listed diameter of 450 mm and a height of 765 mm.
The listed connector size for the three models is 1 inch. The installer should confirm the exact connection standard and fitting details before installation.
The supplied technical data lists a precharge pressure of 1.8 to 2.0 bar. The final setting should be adjusted according to the pump-start pressure and the supplier’s installation instructions.
It may be suitable for a drinking-water system if the selected membrane, coatings, seals, and wetted components comply with the applicable regulations. Certification should be confirmed for the destination market and exact product configuration.
Neither material is universally better. The correct choice depends on water quality, temperature, application requirements, regulatory conditions, and compatibility with the fluid. Butyl and EPDM are both listed options, but the supplier should confirm the recommended material for the intended use.
Outdoor installation may be possible if the tank is protected from freezing, direct impact, standing water, excessive heat, aggressive chemicals, and severe environmental exposure. Additional corrosion protection or shelter may be required.
The tank stores pressurized water and supplies small demands without immediately starting the pump. The pump starts only after the system pressure falls to the control start setting, reducing unnecessary start-stop operation.
No. The nominal tank volume is not the same as usable drawdown. Actual delivered water depends on precharge pressure, pump start and stop settings, system pressure, membrane condition, and other operating factors.
Check the tank precharge, pressure-switch settings, membrane condition, check valve, system leakage, and tank sizing. A qualified technician should depressurize the system before checking or adjusting the air side.
Membrane replacement should be performed by qualified personnel. The tank must be fully depressurized before disassembly, and the correct replacement membrane and sealing components must be used.
Buyers should provide the required capacity, pressure rating, membrane material, application, fluid, temperature range, connector requirement, quantity, destination country, packaging needs, and any certification or documentation requirements.
