FAQs

How does the EP Flexible Impeller Pump work?

This pump operates by the rotation of the internal shaft, which causes the flexible impeller to bend against the casing, pushing fluids and solids out of the discharge port.

What is the difference between a Centrifugal and a Flexible Impeller Pump?

A Centrifugal Pump is a Rotodynamic pump that passes energy from the motor to the liquid, which forces the fluid out of the discharge port. Whereas the Impeller Pump is a Positive Displacement Pump that traps small amounts of liquid and forces it from the suction to the discharge port.

Is this pump suitable for abrasive or hazardous chemicals?

Suitability depends on the application and material selection. The EP range offers impellers in Natural Rubber, Neoprene, NBR, EPDM and Silicone, plus various mechanical seal options. While this allows handling of many different fluids, they are not primarily intended for highly abrasive media or aggressive chemicals without carefully matching your materials to suit.
