Type HZ is a single or multi-stage centrifugal pump with shaft seal.
To achieve low NPSH values, the suction stand is designed as an inlet spiral 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 bearing of the pump shaft takes place in a cylindrical ball bearing and a double-sided angular contact ball bearing.
The pumps can be operated both in the direction of rotation right and left.
The lateral arrangement of the suction nozzle is available as a variant.
