Seal Less Self Priming Magnetic Drive Pumps (SP SERIES)
Principles of self-prming pumps
During pump installation, the priming housing is filled through the fill port. As priming begins, air in the suction piping mixed with liquid in the priming chamber forms a vacuum in the inner volute. As they separate, the air rises out of the discharge piping while the liquid returns to the priming chamber. The circulation process continues until liquid replaces all the air in the suction piping, beginning the pumping process.
When the pump is shut off, the priming chamber’s gooseneck design ensures that enough liquid is retained for efficient re-priming.
