Type HZA is a single or multi-stage centrifugal pump with shaft seal.
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.
