Type HZMA is a single or multi-stage centrifugal pump with magnetic coupling and axial suction flange.

The pump is equipped with a permanent magnet coupling, and the containment shell hermetically seals the conveying medium to the outside.

The pump shaft is supported by SiC sleeve bearings, while the drive shaft is placed in permantently lubricated antifriction bearings. Wear rings are standard on the suction and pressure sides.

Axial thrust compensation occurs by a double-sided discharge disk whose discharge chambers are pressurized by the pressure side of the pump as well as by the pressure of the first stage.
