Ebara 3M Series Centrifugal Pump

Monobloc EN733 Stainless Steel Pump

The Ebara 3M Series is a monobloc centrifugal pump standardised to EN733, manufactured in AISI 304 stainless steel, with the motor directly flanged to the pump body with no coupling or intermediate shaft. It suits civil, agricultural, and industrial water supply, pressure boosting, heating systems, irrigation, and firefighting.

Monobloc Construction and Back Pull-Out

The monobloc design gives the 3M a compact footprint and reduces alignment requirements compared to the coupled 3S and 3P variants. Despite the direct motor connection, the 3M retains the back pull-out design common to the entire 3 Series, allowing the hydraulic assembly to be removed without disturbing the pipework. Maximum working pressure is 10 bar and maximum liquid temperature is +90°C on the standard build.

Available in 2 and 4 Pole Configurations

The 3M is available with 2 or 4 pole motors, giving flexibility for applications where lower speed operation is required. MEI exceeds 0.4 in line with ErP regulations, and the 3LM version provides the same configuration in AISI 316 stainless steel for more corrosive duties.

The 3M is a monobloc EN733 standardised centrifugal pump in AISI 304 stainless steel, where the motor is directly flanged to the pump body with no intermediate coupling.

The monobloc configuration is more compact, requires no shaft alignment on installation, and has fewer components than the coupled alternatives, making it a simpler and lower-cost choice for standard duties.

The 3M is available with 2 pole (higher speed) and 4 pole (lower speed) motors, giving flexibility for different head and flow requirements.

The 3M is designed for clean water and moderately aggressive fluids. The E and ES versions extend compatibility to drinking water and glycol solutions.
