Self-priming centrifugal pump
WP, SMV series DICKOW PUMPEN KG

Field of application

The side-channel pumps are selfpriming and operate more economically (better efficiency) than normal centrifugal pumps, when handling low flows and high heads.
Due to these facts, the side-channel pumps are appropriate to solve many pumping problems in industrial processes. They can be used for almost al liquids which are free of any abrasive solids and of suitable viscosity.
The vertical side-channel pumps are suitable especially for tank farms with underground storage tanks with a diameter of max. 2,5 m (8.2 ft). The construction of the pumps enables an installation directly on the dome cover. That means, suction lift is only slightly above the tank diameter and the priming pipe can be kept short.
For handling toxic, explosive and other dangerous liquids in chemical and petrochemical industries, a sealless pump design with permanent magnetic coupling - without shaft duct to the atmosphere - is also available. Since the static containment shell forms a closed system with hermetically sealed liquid end, an operation with zero leakage is granted. These pumps are maintenance free because no shaft sealing is provided.

Construction

The WPV / SMV-types are single stage, closecoupled, selfpriming Inline-pumps. The opposite located suction- and discharge flanges have identical nominal widths and pressure ratings. The pumps consist of the socket, the suction and pressure disk, the bearing housing and the impeller.
The WPV-bearing housing holds the mechanical seal and the SMV-housing the sleeve bearings.
