PUMP DESIGN e-HM

The e-HM is a non-self-priming, end-suction horizontal multistage, high pressure centrifugal pump, with axial threaded inlet and radial threaded outlet. The pumps are close-coupled design and are equipped with non-standard Lowara motors. The e-HM is equipped with mechanical seal.
The e-HM are highly modular pumps  that are fitted with an innovative hydraulic design that secures high efficiency performances and an increased Mean Time Between Failure.

The e-HM are available in two  different configurations:

– “Compact” design for sizes 1HM, 3HM and 5HM up to 6 stages

– “Sleeve” design for sizes 1HM, 3HM and 5HM from 7 stages and above; any model of 10HM, 15HM and 22HM.
