Self-priming Pumps

Compared to the non self priming pump, the self priming pump can empty the gas in the inlet pipe and pump the liquid into the lower position. Reliably solves the problems caused by valve defects and the vaporization of the liquid part of the problem. Evacuation time is short, high efficiency and no fault operation, high life cycle low cost. Suitable for pumping clean and lightly contaminated liquids, for water supply, dehydration, pressurization systems and irrigation.
