Introduction

The HHM/HEM series non-self-priming horizontal multistage centrifugal pumps e ciently move liquids using centrifugal force generated by a rotating impeller. The pump’s customized motor connects the impeller and guide vane mechanical seal through the motor sha , all mounted securely on a baseplate for stability.

The HHM/HEM series adopts a pull-back design with an axial thread inlet and radial thread outlet. The impeller design minimizes axial thrust on the motor bearing, extending the motor’s lifespan. Di erentiated solutions are available to t speci c needs in residential, industrial, and building service applications.

The HHM/HEM series features a pull-rod system that tightly seals the O-ring against the external guide vane, securing it to the motor ange. This design minimizes leaks and improves overall performance, making the pump a reliable choice for long-term use.
