Product Description

The DESMI SA self-priming centrifugal pump
DN 20 to 200, Up to 400 m³/h

The diffuser principle in the self-priming DESMI SA centrifugal pump means that the priming capacity is not dependent on valves or other mechanical elements since it is the liquid flow which carries the air.The SA pump used within different applications and markets.

Design Features
For priming, the pump casing is filled with liquid prior to starting.Due to the rotation of the impeller the liquid is immediately pumped from suction chamber through impeller into air separating chamber.

Due to the negative pressure thus created in the impeller eye, liquid is drawn through the return passage into the impeller. Due to the negative pressure in the pump, the check valve opens so as to draw air from the suction line into the pump where liquid and air are mixed and proceed through the passage into air separating chamber.
