The Working Principle of PVDF Self-priming Pump

Introduction of PVDF Self-priming Pump:

PVDF self-priming pumps are different from general centrifugal pumps. Before the centrifugal pump works, the pump body and the water inlet pipe must be filled with water to form a vacuum state. When the impeller rotates rapidly, the blades make the water rotate quickly, and the rotating water flies away from the impeller under the action of centrifugal force. After the water is thrown out, the central part of the impeller forms a vacuum area. The water in Suwon is pressed into the water inlet pipe through the pipe network under the action of atmospheric pressure (or water pressure). In this way, continuous pumping can be achieved.

The PVDF self-priming pump does not need to irrigate water, which is the origin of the self-priming pump.

PVDF Self-priming Pump

Self-priming principle of PVDF self-priming pump: due to the special design of the pump casing. Its sealing performance is higher than that of ordinary centrifugal pumps, and the water in the pump casing will not be automatically emptied after the motor is stopped. The motor drives the turbine to rotate at a high speed, and quickly forms a negative pressure (vacuum) in the pump. Use atmospheric pressure to press the water to the pump casing, and then centrifuge the lift. Therefore, the suction stroke of the PVDF self-priming pump will not exceed one atmospheric pressure, about 11M.
