Flexible impeller pumps have a unique design whereby the impeller is made from rubber and manufactured too small to fit fully inside the pump casing. This means that the impeller bends as it rotates inside; this design is what gives the pump special characteristics, such as the ability to self-prime from dry up to 6m vertically, handle solids, handle high-viscosity fluids and provide a non-pulsating gentle pumping action for shear-sensitive fluids.

These pumps have numerous other advantages that set them apart from other pump types:

1. they are compact, can be installed in various positions and the pump head can be rotated to allow the inlet/outlet connections to be positioned how the operator desires. They can handle thin liquids such as water and diesel

2. They are used in a wide range of industries including chemical, cosmetic, food, beverage and pharmaceutical; this is because the casing can be manufactured in either 304 or 316 stainless steel and the impellers can be manufactured in various materials including NBR, Neoprene, EPDM, Silicon and Natural rubber depending on the nature of the fluid.

Gentle pumping action ensuring the consistency of the fluid remains unaffected by low shear forces e.g. milk, cream, thixotropic fluids.

3. Convenience for the operator is paramount in the design of this equipment. These impeller water pump can also be operated in reverse for applications such as tanker loading/offloading; this is performed by simply flicking switch on the motor.

4. High capacity as can operate at full motor speed with low viscosity fluids

5. Versatile - electric impeller pump can be run at different speeds to accommodate differing viscosities

6. Easy Maintenance due to few moving parts
