How Flexible Impeller Pumps Work
- Flexible Blades
- The impeller is made of flexible rubber or elastomer blades mounted on a rotating hub.
- These blades bend and conform to the shape of the eccentric cam inside the pump housing.
- Pumping Action
- As the impeller rotates, liquid is trapped between the blades and the pump wall.
- The cam compresses the blades, squeezing the liquid toward the discharge port in a smooth, continuous flow.
- Flow Control
- The pump can be throttled or temporarily shut off without damage or the need for a relief valve—ideal for variable flow conditions.
