Mini Monoblock Pumps

A mixture of water air is used to reach a state of the fully primed pump. A low-pressure zone at the center is created, when the impeller located inside the casing rotates. The pressure difference inside the casing and the outside air causes a suction effect that results in water moving up the suction pipe. The self-priming pump mixes the air with recirculating water, all the air in the suction pipe is displaced and the water is discharged.
