DESMI A/S
DESMI - Model SA Series -Horizontal Self-priming Centrifugal Pump
FromDESMI A/S
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.

- 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.
- The water velocity in the air purging space is so low that the air is separated from the liquid, and the vented water carries on the circuit through the return passage and the impeller until the total air content of the suction pipe has been separated.
