Sealless Magnetic Coupled Multistage Centrifugal Pumps with Priming Stage Type HZSM / HZSMB / HZSMR / HZSMA / HZSMAR

General

DICKOW-pumps of series HZSM are sealless multistage horizontal centrifugal pumps, driven by a synchronous permanent magnetic coupling. The static containment shell forms a closed system with hermetically sealed liquid end. The integrated side channel stage allows the handling of entrained gas and operation under suction lift conditions.

Application

Magnetic driven HZSM-pumps are designed to improve plant and personnel safety, especially when handling toxic, explosive or other dangerous liquids which react on contact with the atmosphere. For all these services the containment shell replaces the double acting mechanical seal with external fluid reservoirs and the necessary control equipment. HZSM-pumps therefore offer exceptional benefits to the chemical, petrochemical and allied industries, and protect the environment.

The HZSM-type is used in tank farms, for offloading rail cars and trucks, filling of storage tanks and other applications where priming of empty suction pipes is required. Considering low NPSH-values, gas handling capability and sealless design, the HZSMA-type offers special benefits to liquified gas applications. Typical application is filling of LPG-trucks and rail cars in refineries. The maximum operating temperature is 180°C.
