HZ/HZA-pumps are applied in industrial and municipal water supply, for handling condensates boiler feed water, fuels and for various other applications.
The type HZA of end suction design has been developed for operating conditions with low NPSHA-values. The wear resistant SiC-sleeve bearing on the suction side reduces the maintenance costs because there is no second mechanical seal required.
The performance range is subdivided to achieve best efficiencies for all service conditions.
With a wide selection of materials and the possibility of applying several shaft sealing systems as well as a hermetically sealed permanent magnetic coupling, the HZ / HZA- pumps are suitable for handling almost all kinds of liquids which are free of abrasive solids and of suitable viscosity.
