Flexible Impeller Pumps

The flexible impeller pump, or flexible vane pump as it is otherwise referred to, is a versatile pump design, part of the positive displacement pump family. Thanks to the supple nature of the impellers, as they rotor they are connected to turn, they bend to push the fluid from the pump inlet to its outlet. The beauty of the flexible impeller pump is it's versatility thanks to the multiple materials the impellers are available in. It serves a wide range of applications and industries at a lower relative cost than other pumping technologies that can handle fluids of all types including solids, viscous slurries, light water based fluids and lubricating oils.  Flexible Impeller Overview Brochure
