The HF/HC/HE series horizontal multi-stage centrifugal pumps adopt an axial thread inlet and a radial thread outlet
backward-pull-out structure design. Its stable-type impeller design reduces the axial thrust borne by the motor shaft,
thus extending the service life of the motor bearing.
For the HL series integrated design: It connects a single stainless-steel water inlet body directly to the motor flange,
using an O-ring as a sealing sleeve, which reduces the possibility of leakage.
The HF/HC series segmental design: It uses tie-rods to tightly seal the external-type guide vanes with O-ring rubber
gaskets and secures them to the motor flange.
The HE series cartridge design: It consists of a single stainless-steel welded casing and a single suction casing, held
together by a forged pump support and tie-rods tightened to the motor flange.
