Multi-stage magnetic drive centrifugal pump
max. 200m³/h | HMZR series DICKOW PUMPEN KG

General
Dickow-pumps of series HZMR are sealless multistage horizontal centrifugal pumps, driven by a synchronous permanent magnetic coupling.
The containment shell is sealed by a confined gasket and separates the pumped liquid from the atmosphere. There are no leakage endangered dynamical shaft sealings available.

Due to the fact that 90% of pump failures are caused by leaking shaft seals, the sealless design increases the availability and reduces maintenance costs.

Field of application
HZMR-pumps are used in services where no seal leakage can be tolerated, when handling toxic, explosive and pollutive liquids and when the required differential heads are above the application range of single stage volute casing pumps.

The HZMR-pumps operate almost maintenance free, the service life is far longer than that of pumps with conventional mechanical seals.

The performance range covers capacities up to 200m3/h (880 USgpm) and differential heads up to 350mLC (1148 ft). The maximum operating temperature is approx. 200°C (392°F), allowable operating pressure is 40 bar.
