Centrifugal pump HZMA

Product description
Type HZMA is a single- or multi-stage centrifugal pump with permanent magnetic coupling and an axial suction port. The magnetic coupling and containment shell hermetically isolate the pumped fluid from the external environment. An internal circulation flow dissipates heat generated by eddy-current losses. The pump shaft is supported by SiC plain bearings on the product side; the drive shaft runs in permanently grease-lubricated ball bearings. Wear rings are standard on both suction and discharge sides. Axial thrust is compensated by a double-sided relief disc with chambers acted upon by both the pump discharge and the first-stage pressure. The pump is designed for horizontal installation.
