The AUDP Series Centrifugal Pump is designed for dependable water transfer in homes, gardens, farms, workshops, commercial facilities, and light industrial environments. Combining a practical centrifugal hydraulic design with durable motor components and flexible installation options, the pump provides an efficient solution for users who need stable water delivery without unnecessary complexity.
Water-pumping requirements vary considerably from one project to another. A household may need water supplied from a well or reservoir, while an agricultural user may require irrigation support. A small industrial facility may need a dependable pump for process water, cleaning, or general circulation. The AUDP Series is developed to address these common requirements with a compact construction, straightforward operation, and a selection of component options suitable for different water-supply conditions.
Manufactured by Taizhou Edwin Electric Co., Ltd., the pump benefits from the company’s experience in research and development, mass production, product organization, and international export. Since its foundation in 2008, the company has developed a broad portfolio that includes deep well pumps, submersible pumps, domestic booster pumps, circulation pumps, solar water pumps, intelligent booster pumps, and other water-treatment-related products. This broad product knowledge supports the development of centrifugal pumps that can be integrated into a wider water-supply system.
The AUDP Series is particularly suitable for buyers looking for a general-purpose pump with useful material choices, built-in motor protection, and adaptable configuration. Its combination of stainless steel, copper, brass, and engineered polymer components gives purchasers the flexibility to balance durability, cost, and application requirements.
AUDP Series Centrifugal Pump
A centrifugal pump transfers liquid by converting mechanical energy from an electric motor into fluid movement. The motor rotates an impeller, and the impeller accelerates the water outward through centrifugal force. The pump casing then guides the water toward the discharge outlet. This operating principle is widely used because it is mechanically straightforward, easy to maintain, and suitable for a wide range of water-transfer applications.
The AUDP Series Centrifugal Pump is intended for water supply from wells or reservoirs, domestic water use, civil and industrial applications, garden watering, and irrigation. It is designed for clean or relatively clean water conditions within the stated operating limits. The pump can be used as a standalone water-transfer unit or incorporated into a larger system with a pressure controller or tank assembly.
Its practical configuration makes it suitable for customers who do not require a highly specialized process pump but still expect reliable construction and consistent everyday performance. Instead of focusing only on maximum output, the design emphasizes balanced operation, serviceability, and compatibility with common water-supply arrangements.
The pump is supported by a copper-wound motor, a built-in thermal protector, and a stainless steel welded shaft. Depending on the buyer’s preference and intended water conditions, the impeller can be supplied in brass, AISI SS304 stainless steel, or PPO engineering polymer. Different cable lengths can also be requested, allowing the pump to be adapted to various installation layouts.

The specifications show that the AUDP Series is designed around practical installation needs. The maximum suction capability of 8 meters is useful for many well, reservoir, and surface-water arrangements, although the actual result will depend on pipe length, pipe diameter, elevation, fittings, water level, and installation quality.
The maximum fluid temperature of +40°C indicates that the pump is primarily intended for cold or moderately warm water rather than high-temperature industrial liquids. Similarly, the stated maximum sand content of 0.25% defines the acceptable level of suspended abrasive material. Users should evaluate the water condition before installation and use appropriate filtration or pre-treatment if necessary.
The centrifugal design offers a useful balance between water flow, pressure generation, and mechanical simplicity. For domestic water supply, irrigation, and general transfer duties, this type of pump is often easier to install and maintain than more complicated pumping systems.
A well-designed centrifugal pump can provide steady water movement without the pulsation associated with some positive-displacement technologies. This makes it appropriate for garden watering, household supply, water transfer between tanks, and many civil or industrial applications where smooth delivery is desirable.
The AUDP Series is not presented as a specialized pump for every possible liquid or process condition. Its strength is its versatility within the water-pumping field. By focusing on common water-supply tasks, the design remains accessible to installers, distributors, and end users who need a reliable pump for regular service.
The motor uses copper winding, a feature valued in electric pump construction because copper provides good electrical conductivity and supports efficient transfer of electrical energy into motor torque. Copper windings can also contribute to stable motor operation when the pump is correctly selected, installed, and supplied with the appropriate voltage and frequency.
For buyers comparing general-purpose pumps, the use of copper winding is an important consideration. Some lower-cost products may use less desirable winding materials or may provide limited information about motor construction. Clear specification of copper winding helps purchasers assess the product more confidently and compare it with competing pumps on a meaningful technical basis.
Motor performance still depends on correct operating conditions. The pump should be connected to a suitable power supply, protected against abnormal voltage conditions, and installed with appropriate electrical equipment. The built-in thermal protector provides an additional layer of motor protection, but it does not replace correct system design or professional electrical installation.
Electric motors can generate excess heat because of overload, restricted water flow, voltage problems, repeated starting, blocked ventilation, or mechanical resistance. The AUDP Series incorporates a built-in thermal protector to help reduce the risk of motor damage caused by excessive temperature.
This feature is valuable in domestic and agricultural environments where operating conditions may change during the day. For example, a pump may face variations in water demand, pressure, or suction conditions. Thermal protection can help safeguard the motor when abnormal heat develops, improving operational confidence and reducing the risk of premature failure.
Thermal protection should be viewed as part of a complete protection strategy. Installers should still use suitable circuit breakers, grounding, switches, and control devices in accordance with local electrical requirements. The pump should also be kept free from conditions that could cause continuous overload.
The stainless steel welded shaft is another important construction feature. The shaft transfers motor rotation to the impeller and therefore experiences continuous mechanical movement. A stainless steel shaft can provide useful resistance to corrosion in ordinary water environments and helps support long-term reliability when the pump is properly maintained.
Compared with a basic untreated metal shaft, stainless steel offers a more suitable material choice for water-handling equipment. The welded construction is intended to provide a secure connection within the rotating assembly. As with any pump, the final service life will depend on water quality, bearing or seal condition, alignment, electrical stability, and the frequency of operation.
The AUDP Series can be configured with brass, AISI SS304 stainless steel, or PPO impellers. This choice is a significant advantage for distributors and project purchasers because it allows the product to be matched to different performance, durability, and budget expectations.
Brass is widely used in pump components because it offers a useful combination of strength, machinability, and resistance to ordinary water exposure. It can be an appropriate choice for many domestic, garden, and general water-supply systems.
AISI SS304 stainless steel is suitable for users who place greater emphasis on corrosion resistance and material durability. Stainless steel may be preferred in installations where the visual appearance of the component, long-term material stability, or more demanding environmental conditions are important.
PPO, or polyphenylene oxide, is an engineering polymer used in applications where low weight, dimensional stability, and economical production are valued. A PPO impeller may help reduce overall component weight and provide a cost-effective solution for suitable clean-water applications.
These options give the pump a broader market range than a product restricted to one impeller material. A purchaser can select the configuration according to water quality, system requirements, project budget, and expected service conditions.
One advantage of the AUDP Series over many basic fixed-configuration pumps is its adaptability. The availability of different cable lengths, impeller materials, frequency options, pressure-controller compatibility, and tank-system assembly allows the product to be prepared for different markets and installation conditions.
A fixed product may force the installer to modify the wiring, replace components, or purchase additional equipment after delivery. By contrast, an order configured in advance can reduce installation inconvenience and help distributors serve multiple customer groups with a consistent product platform.
The combination of copper winding and built-in thermal protection gives the AUDP Series a stronger practical position than very basic pumps that provide limited motor protection. A pump is often installed in locations where users cannot continuously monitor temperature, load, or operating time. Integrated protection therefore adds meaningful value.
Protection features do not make a pump immune to misuse, but they can improve its resilience during ordinary service. For households, gardens, farms, and small commercial facilities, this can translate into greater confidence and potentially lower maintenance risk.
Offering brass, stainless steel, and PPO impeller choices enables the product to compete across more than one price segment. An economical installation may benefit from an engineering-polymer impeller, while a buyer seeking a more robust material may select stainless steel. Brass provides another balanced option for general water service.
This approach is useful for importers and wholesalers. Rather than sourcing separate pump platforms for different price levels, a distributor may be able to organize several versions within the same product family. This simplifies product education, spare-parts planning, and customer support.
The AUDP Series is intended for water supply from wells or reservoirs, domestic applications, civil and industrial use, garden watering, and irrigation. This broad application range gives it an advantage over narrowly designed pumps that can only serve one type of installation.
For a contractor, versatility can simplify project procurement. A pump that can support several common water-transfer tasks may reduce the number of product types that must be evaluated. For a distributor, it can make inventory planning easier and improve the opportunity to serve residential, agricultural, and commercial customers.
The pump can be connected with a pressure controller and can also be assembled with a tank system. These options make it more suitable for automatic water-supply arrangements. A pressure controller can help manage pump starting and stopping based on system demand, while a tank system can support pressure stability and reduce unnecessary cycling in suitable installations.
These accessories should be selected according to the actual system design. Pipe size, pressure requirements, tank volume, control settings, check valves, and water demand all affect the final result. Nevertheless, the pump’s compatibility with these arrangements provides a useful foundation for creating a more complete water-supply package.
The AUDP Series can be used to transfer water from a well, reservoir, storage tank, or other suitable source to a house or small property. It may support general non-potable water duties, household supply arrangements, or auxiliary water systems, provided that the complete installation meets local regulations and the water quality is appropriate for the intended use.
In a domestic installation, the pump can be combined with a pressure controller or tank system to provide more convenient water delivery. A correctly selected system may help supply bathrooms, utility areas, outdoor taps, and other water-use points. Installers should verify the required flow and pressure before choosing the final pump configuration.
Garden irrigation often requires a compact and dependable pump that can draw water from a tank, pond, reservoir, or shallow well. The maximum suction specification of up to 8 meters may be suitable for many garden layouts, although the practical suction height must account for pipe friction and source conditions.
The pump may be used with sprinklers, hoses, drip irrigation equipment, or small distribution systems. For efficient garden operation, users should avoid undersized pipes, excessive bends, leaking connections, and blocked filters. Such problems can reduce flow and increase the load on the pump.
Small farms, nurseries, greenhouses, and agricultural plots can use centrifugal pumps to move water from reservoirs or wells to irrigation networks. The AUDP Series may be suitable for general irrigation duties within its water-quality and operating-temperature limits.
Agricultural users should consider seasonal demand, total pipe length, elevation changes, irrigation method, and required operating hours. A pump suitable for a small vegetable garden may not be sufficient for a large field or high-pressure sprinkler network. Proper hydraulic calculation is essential before installation.
In civil and commercial environments, the pump may support general water transfer, building service systems, cleaning operations, landscape irrigation, and auxiliary supply duties. Its compatibility with pressure controllers and tank systems can be useful in small commercial properties, workshops, offices, and service facilities.
The pump should not be selected solely by connection size or motor power. A professional assessment should consider the required flow rate, total dynamic head, suction conditions, duty cycle, water quality, and control method. These factors determine whether a centrifugal pump is the correct solution for a particular building system.
Industrial users may apply the AUDP Series to general water movement, equipment cleaning, utility water, cooling support, and other non-specialized duties. The maximum water temperature of +40°C means that the product is intended for relatively cool water rather than hot process liquids.
Before using the pump in an industrial environment, the purchaser should confirm chemical compatibility, suspended solids, operating hours, ambient conditions, and required protection levels. If the liquid contains aggressive chemicals, high concentrations of abrasives, oils, or elevated temperatures, a specialized pump may be necessary.
Taizhou Edwin Electric Co., Ltd. operates as an integrated manufacturing enterprise with independent research and development, mass production, and global export capabilities. This integrated structure is valuable because product design, manufacturing, order management, and market feedback can be coordinated within one broader organization.
Independent research and development allows the company to refine product structures according to customer needs and application trends. For a pump manufacturer, this may include improving hydraulic layouts, selecting appropriate materials, developing intelligent control solutions, and adapting products for different voltage and frequency markets.
The AUDP Series reflects a practical development philosophy. Rather than relying on a single standard configuration, it provides several component and installation options. This indicates attention to the actual needs of distributors, contractors, and end users operating in different regions.
Mass production provides important advantages for international buyers. It supports more consistent product availability, repeatable assembly procedures, and the ability to handle larger or recurring orders. For distributors, stable production capacity can help reduce supply interruptions and improve inventory planning.
Repeatable manufacturing is especially important for pumps because the motor, shaft, impeller, seals, casing, and electrical components must work together accurately. Consistency in assembly and inspection contributes to dependable performance across different production batches.
The company’s product range includes multiple pump categories, such as deep well pumps, submersible pumps, domestic booster pumps, circulation pumps, solar water pumps, and intelligent booster pumps. Experience across these categories can support shared knowledge in motor technology, water handling, control systems, and product testing.
Edwin Pump serves customers in the global market and has developed related import and export service organizations to support procurement planning, order tracking, cross-border delivery, and foreign trade services. This is an important strength for international buyers because successful pump supply involves more than manufacturing alone.
Export customers often require clear specifications, packaging coordination, documentation, shipment scheduling, and communication across different time zones. A professional foreign-trade structure can help connect production with these commercial requirements.
For wholesalers and project buyers, one-stop procurement support may reduce the effort involved in sourcing several water-pump categories from different suppliers. The company’s wider product portfolio also creates opportunities for coordinated purchasing of complementary equipment.
Since 2018, the company has invested in new-energy and intelligent technology, including solar water pumps and intelligent booster pumps. This development demonstrates an effort to respond to changing market expectations, including energy efficiency, automated operation, remote or intelligent control, and water access in areas with limited grid availability.
Although the AUDP Series is a conventional centrifugal pump, its availability within a manufacturer that also develops intelligent and solar pumping products can be beneficial to buyers. Customers may begin with a standard pump for a current project and later require a solar, booster, or intelligent solution for another application.
This broader technological direction can also influence product development. Knowledge gained from intelligent pump systems may support better attention to control compatibility, motor protection, system integration, and energy-conscious operation across the product portfolio.
Reliable pump production depends on disciplined control of materials, motor components, rotating assemblies, sealing parts, electrical connections, and final testing. The AUDP Series uses several specified materials, including copper winding, stainless steel shaft construction, and selectable impeller materials. Clear material definition helps maintain product consistency and gives buyers a basis for quality evaluation.
During manufacturing, the motor winding must be assembled with care to ensure suitable electrical performance. The rotating shaft and impeller require proper alignment to limit vibration and mechanical stress. The casing and hydraulic passages must be assembled securely to support stable water movement. Electrical connections should be inspected for safe operation and reliable service.
Quality is also affected by packaging and transport. Pumps may be shipped across long distances and handled through multiple logistics stages. Appropriate protective packaging helps reduce the risk of impact damage, moisture exposure, or deformation before installation.
For business customers, quality assurance should include more than a visual inspection. Buyers may request product specifications, operating instructions, sample evaluation, packaging details, spare-parts information, and confirmation of the applicable warranty terms. The one-year warranty for the AUDP Series is provided according to the manufacturer’s general sales conditions, so purchasers should review those conditions before placing an order.
Correct installation is essential for achieving the expected performance of any centrifugal pump. The pump should be placed on a stable foundation and protected from unnecessary vibration, flooding, extreme weather, and mechanical impact. The installation area should provide sufficient access for inspection and maintenance.
The suction pipe should be appropriately sized, securely connected, and arranged to minimize air entry. Leaks on the suction side can seriously reduce pumping performance and may prevent the pump from maintaining prime. Where required, a foot valve or check valve may help retain water in the suction line, depending on the system design.
The suction lift should remain within the stated maximum of 8 meters, while the actual system must also account for friction losses and elevation. A nominal suction height below the maximum may still produce unsatisfactory results if the pipe is too narrow, excessively long, or fitted with many elbows and restrictions.
The pump should be primed according to the installation instructions before operation. Running a standard centrifugal pump without sufficient water can cause overheating, seal damage, or loss of performance. Users should confirm that water is available and that the pump is not operating dry.
Electrical installation should be carried out by a qualified professional. The voltage and frequency must match the selected pump configuration. The system should include proper grounding and suitable electrical protection. The built-in thermal protector is helpful, but it should be used together with appropriate external protection and a correctly rated power supply.
Discharge piping should be supported independently so that its weight does not place stress on the pump casing or connections. Threaded joints should be sealed properly, but excessive sealing material should not enter the hydraulic passage. After installation, the system should be checked for leaks, unusual noise, vibration, overheating, and unstable pressure.
Routine maintenance helps preserve pump performance and extend service life. Users should inspect the pump periodically for water leakage, abnormal sound, vibration, corrosion, loose connections, and changes in flow or pressure. Early detection can prevent a small problem from becoming a major failure.
Filters and strainers should be cleaned according to the water condition. The stated maximum sand content is 0.25%, but even within that limit, abrasive particles may affect seals, impellers, and other internal components over time. If the water source contains visible sediment, the system should include suitable filtration or settling arrangements.
The pump should not be operated with blocked suction or discharge lines. A restricted suction line can cause poor performance and may increase the risk of cavitation. A restricted discharge line can alter the operating point and increase mechanical or thermal stress in some conditions.
When the pump is used seasonally, such as for garden irrigation, it should be prepared for periods of non-use. The system may need to be drained in locations where freezing is possible. Electrical power should be disconnected before inspection, cleaning, or service work.
Replacement components should be selected according to the correct model and specification. The impeller material should not be changed without confirming compatibility with the pump design and operating conditions. Professional service is recommended for motor, shaft, seal, and electrical repairs.
The first step is to determine the required flow rate. Flow rate describes how much water must be delivered within a specific period. A household, irrigation system, and industrial process may each require different flow levels. Overestimating or underestimating flow can result in inefficient operation or insufficient water supply.
The second step is to calculate total head. Total head includes vertical lifting height, required outlet pressure, and friction losses in the pipe network. Buyers should not consider only the distance from the water source to the destination. Pipe length, diameter, valves, filters, elbows, and fittings all contribute to resistance.
The third step is to evaluate suction conditions. The AUDP Series has a maximum suction specification of 8 meters, but practical performance depends on atmospheric pressure, water temperature, elevation above sea level, pipe configuration, and the condition of the suction line.
The fourth step is to review water quality. The pump is intended for water with a maximum sand content of 0.25% and a maximum fluid temperature of +40°C. If the water is hotter, highly abrasive, chemically aggressive, oily, or contaminated with large solids, the buyer should consult the manufacturer about a different solution.
The fifth step is to select the impeller material. Brass may suit many general applications, AISI SS304 may be chosen for enhanced material durability and corrosion resistance, and PPO may be appropriate when a lighter or more economical configuration is preferred for suitable water conditions.
The final step is to determine control and installation options. Users may request different cable lengths, connect a pressure controller, or assemble the pump with a tank system. Voltage and frequency should also be confirmed because the product can be configured for 50 Hz or 60 Hz markets.
Although the AUDP Series is a centrifugal transfer pump, it can be connected with a pressure controller for suitable water-supply applications. This can make it useful in situations where water demand changes throughout the day, such as household taps, garden hoses, or small commercial facilities.
A pressure controller can automate pump operation by responding to changes in system pressure or flow. When a water outlet is opened, the controller may start the pump; when demand stops, it may stop the pump. The control strategy must be selected and adjusted according to the pump’s performance range and the requirements of the complete system.
A tank system offers another configuration option. A properly sized pressure tank can help reduce frequent starts, stabilize pressure, and provide a reserve volume for small demands. Tank pre-charge, controller settings, pipe arrangement, and pump characteristics must be coordinated for effective operation.
These options make the AUDP Series more adaptable than a pump intended only for manual on-and-off operation. However, automatic systems still require correct installation, protection against dry running where necessary, and regular inspection of pressure and electrical components.
International buyers often need a pump platform that can be adapted to different electrical standards and market expectations. The availability of 50 Hz and 60 Hz options supports use in multiple regions, while different cable lengths can help accommodate local installation practices.
The selection of impeller materials also supports market segmentation. A distributor may offer a standard version for everyday domestic use, a stainless steel version for customers seeking a more durable material, and a PPO version for cost-sensitive applications where the water conditions are suitable.
The manufacturer’s experience in global export and foreign-trade service adds practical value. Procurement planning, order tracking, cross-border delivery, and communication are all important when buying pumps internationally. A supplier that understands these requirements can help reduce avoidable delays and misunderstandings.
The company’s broader portfolio is another advantage. Customers who need several pump categories may be able to source deep well pumps, submersible pumps, booster pumps, circulation pumps, solar pumps, and related accessories through an integrated supplier relationship. This can simplify vendor management and support more consistent product planning.
