Type HZS is a self-priming, single or multi-stage centrifugal pump with shaft seal.
The venting works on the principle of a side channel pump. The liquid present in the pump forms when starting with the amount of air present in the suction line, a liquid - gas mixture, wherein the existing air content is conveyed by the vent in the discharge nozzle. Due to the pressure-side arrangement of the venting stage, a complete venting of suction line and pump body is ensured.
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 pump can be operated both in the direction of rotation right and left.
