Model HZSA

Model : HZSA
Standards: API 610, ISO 5199

Model HZSA is a single or multi-stage centrifugal pump with shaft seal and gas delivery stage.

The gas conveyor operates on the principle of a side channel pump. In gas production, a return of the gas is achieved in the liquid phase by increasing the pressure in the side channel stage.

To achieve very low NPSH values, the suction stand is designed with an axial inlet and the suction side impeller with an enlarged inlet cross section.

The axial thrust compensation takes place through relief boreholes and throttle gaps, wear rings are standard on the suction and pressure sides. The pump shaft is mounted in a double-row angular contact ball bearing and SiC plain bearings.
