EAC Series Close-coupled Direct Connection Simplified Structure HonEnd Suction Centrifugal Pump

Description :

The EAC Series Centrifugal Pump is an innovative solution designed for the efficient and cost-effective pumping of clean, thin liquids. As part of EDWIN Pump's Combi-system, it adheres to the Din24255/En 733 standards, ensuring a high degree of part interchangeability within the EA series pump constructions.

Key Features :

High Interchangeability: Benefits from a modular design that allows for easy part replacement and maintenance, reducing downtime and service costs.

Compact Design: The pump's close-coupled configuration with IEC standard electric motors saves space and simplifies installation.

Versatile Application: Suitable for a variety of liquids, including low-viscosity, clean, slightly contaminated, and aggressive fluids.

Low Maintenance: Thanks to its simple component layout and the inclusion of a mechanical seal, the EAC pump requires minimal upkeep.

Back Pull Out Feature: Allows for easy removal of the rotating assembly without the need to disconnect the pump from the piping system, further reducing maintenance time and effort.

Maximum Flow Rate: Up to 1100 m³/h, ensuring high throughput for various applications.

Head Capacity: Capable of reaching up to 150 meters, suitable for high-lift scenarios.

Temperature Tolerance: Operates effectively within a range of -10°C to +105°C, making it versatile for different environmental conditions.

Service Pressure: Can handle pressures up to 16 bar, depending on the specific model, providing robust performance for demanding applications.

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
