Type HZAR is a single or multi-stage centrifugal pump according to API 610, type BB4, with axial suction port.
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, while running and split rings are standard on the intake and delivery side. The bearing of the pump shafts takes place in a cylindrical roller bearing and an angular contact ball bearing pair.
Replaceable bearing seals are arranged on both sides.
The sealing to the atmosphere is carried out by profiled sealing rings in metal-to-metal design.
The seal chamber is designed so that mechanical seals according to API 682 can be installed.
