Product Description

Product Description

Description :
The DIN 24255 / EN 733 Horizontal Industrial Back Pull-Out End Suction Centrifugal Water Pump is a high-performance pump used for a wide range of industrial applications. It is designed to move liquids, particularly water, efficiently and reliably. Here's a detailed overview of its features, design specifications, and typical uses.

Key features of this pump body include:
 

1. Standard Compliance (DIN 24255 / EN 733)

   • These pumps are manufactured according to the international standards DIN 24255 (Germany) and EN 733 (Europe), ensuring reliability, quality, and interchangeability with other pumps in the same category.

2. Horizontal, End Suction Design

   • The pump features a horizontal installation with an end suction configuration. This makes it particularly suitable for pumping clear water and other non-viscous liquids in various industrial and municipal applications.

3. Back Pull-Out Design

   • The back pull-out design allows for easy maintenance and inspection without disturbing the pipework. The motor and pump casing can be removed without affecting the alignment, making it easier to service and maintain the pump in the field.

4. Single-Stage Centrifugal Pump

   • The pump operates using a single-stage centrifugal mechanism, which efficiently moves water by converting rotational kinetic energy into fluid energy. It is designed for continuous operation and can handle moderate pressures.

5. Durable Materials

   • Constructed from high-quality materials such as cast iron, stainless steel, or other corrosion-resistant alloys to ensure durability and reliability in harsh operating conditions.

6. Wide Range of Flow Rates and Head Heights

   • It is designed to handle a wide range of flow rates (typically from a few m³/h to thousands of m³/h) and head heights (up to 100 meters or more), making it versatile for many industrial applications.

7. High Efficiency and Low Power Consumption

   • The pump is designed for high efficiency in energy consumption, reducing operational costs and minimizing the environmental impact.

Motor power 
As standard, EA pumps are equipped with IM B3 electric motors.
To determine the drive power, we recommend the following safety margins :
Up to 4 kw: +25%
From 4 to 7.5 kw: +20%
Above 7.5 kW : +15%

Applications :
Water Supply Systems
General Transport for Industrial Processes
Fire Fighting Systems
Pressure Boosting
Cooling Plants for Industrial Processing and Air-Conditioning units
Heating Systems for Commercial District Heating

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
