Advantages of vane pump

Flexible impeller pumps solve most of the needs of pumping raw water with high efficiency. These pumps have high self suction and can transport sewage containing solid particles without blocking or damaging the pump. In boats, these pumps have more applications. HJUMBO Pump marine supplies equipment cooling pumps to the world's inboard engine manufacturer.

Self priming flexible impeller pump

working principle

When the flexible impeller leaves the cam and straightens, a vacuum is formed to suck the liquid into the pump.

The rotating impeller transports the liquid from the inlet to the outlet. This allows larger particles to pass through.

When the flexible impeller blade contacts the cam again, the blade bends and the liquid is discharged from the pump at a uniform flow rate. Turning the pump in the opposite direction can also pump liquid in the opposite direction.
