Materials

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™ is available in two different configurations:

  • “Compact” design for sizes 1HM, 3HM and 5HM up to maximum 6 stages
  • “Sleeve” design for sizes 1HM, 3HM and 5HM starting 7 stages and above; any models of 10HM, 15HM and 22HM.

The “Compact” design is made of one single piece fabricated stainless steel pump body directly connected to the motor flange. The “Compact” has only one O-ring for the sealing of the casing that clearly reduces the leakages possibilities.

The “Sleeve” design is made of an external stainless steel TIG welded sleeve and of separate suction casing kept together with the mean of an aluminum casted pump bracket and of stainless steel tie rods screwed in the motor flange.

The e-HM™ is available in three different material execution:

  • HM..P: Stainless steel pump body (EN 1.4301/ AISI 304) with Noryl™ impeller for sizes 1HM, 3HM, 5HM and 10HM to maximum 6 stages.
  • HM..S: full stainless steel (EN 1.4301/ AISI 304) – any models.
  • HM..N: full stainless steel (EN 1.4401/ AISI 316) – any models.
