Multi-stage centrifugal pump
HZ, HZA series DICKOW PUMPEN KG

General

HZ / HZA-Pumps are applicated in the industrial and municipal water supply, in pressure increasing plants, for handling condensates, for boiler feeding, as firefighting pumps 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.

Construction

HZ / HZA-pumps are multistage centrifugal pumps of vertically split casing design.

Suction- and discharge casing

Suction- and discharge casings are provided with sturdy cast feet for mounting on baseplates or base frames. To obtain low NPSH-values, the suction casings of the HZ-pumps are designed volute shape.
HZA-pumps have end suction design to obtain lowest NPSH-values.
