EA Series Reliable Performance Clean Water Horizontal End Suction Fire Centrifugal Pump

Description :

The EA Series Horizontal End Suction Fire Centrifugal Pump is a robust and reliable solution for clean water transfer, designed to meet the demands of fire protection systems and other critical applications. This pump is built to the highest standards, conforming to DIN24255/BESN733, ensuring quality and performance.

Key Features :

Horizontal End Suction Design:

The EA Series features a horizontal end suction and vertical top discharge configuration, providing a space-efficient and straightforward installation process.

Single Stage, Foot Mounted:

As a single-stage pump, it offers high efficiency and reliability. The foot-mounted design ensures stability and ease of integration into existing systems.

True Back-Pull-Out (BPO) Design:

The true BPO design allows for the back plate and rotating assembly to be removed without disturbing the motor, significantly reducing maintenance time and service interruption.

Spacer Coupling:

When equipped with a spacer coupling, the motor remains in place during servicing, further enhancing the ease of maintenance and reducing downtime.

Dimensional Interchangeability:

The pump's adherence to DIN24255/BESN733 standards ensures it can be directly interchanged with other pumps that conform to these international standards, offering flexibility and compatibility with existing systems.

Superior Material Options:

EDWIN Pumps can provide the EA Series pump in superior materials, allowing for direct interchange with other manufacturers' equipment without the need for pipe work or motor changes.

Reduced Equipment Downtime:

The effective design of the EA Series pump minimizes service interruption, allowing for quick and easy maintenance, which is crucial for fire protection systems.

Versatile Applications:

Ideal for fire fighting, water supply, irrigation, and various industrial applications where reliable and efficient water transfer is essential.

Components and Material :

Casing

Open on drive side to enable the mechanical assembly to be dismounted from behind. Mounting feet under the volute casing. Axial suction, radial discharge upwards.

Flanges manufactured to standard NFE 29201(DIN 2533). PN.16.Cast iron or Stainless Steel SUS304/316 as standard.Duplex Stainless Steel 2205 or 2507 can require.

Casing cover

Mounted between the casing and the bearing housing and equipped with housing to receive the mechanical or gland packing shaft seal.

Bearings 

Monobloc, oversized (to standard lSO 5199) and supported by a support foot. Grease-lubricated deep-groove ball bearings guide the motor shaft. A centrifugal deflector prevents the lea-king of liquid.

Shaft

oversized (to standard lSO 5199) for longer mechanical-seal service life. Shaft sleeve.

Impeller 

Cast iron or Stainless Steel SUS304 as standard.High-efficiency closed radial impeller with back seal and balance holes. Adapted trimmed on request to comply with the Q/H required for the application.

Shaft seal

Single standardised mechanical seal adapted to the liquid being pumped. No servicing required during operation. stuffing box possible on request.

Coupling

Standard, semi-elastic coupling. Can be fitted with a spacer coupling on request.

Casing seal

Standard models are sealed using fibre
