Flexible Impeller Pumps

Flexible Impeller Pumps

Flexible impeller pumps are positive-displacement pumps with deforming impeller vanes, drawing liquids into the pump housing and then moving it to the discharge port at a constant flow. The flexibility of the vanes enables a tight fitting seal to the internal housing, this makes the pump self-priming, also permitting a bi-directional operation. The output from flexible impeller pumps tends to be smooth and gentle.
