Flexible Impeller Pumps

Impeller pumps are dry and self-priming rotary pumps. They unite the characteristics of a rotary pump and a positive displacement pump into one.

The working principle is very simple:
The heart of the pump is a flexible wheel (impeller), which is made of an elastomer material called Neoprene and the individual wings of the impeller are strongly bent, due to rotation, against the eccentric plate.

On the priming side, the wings spread apart through residual stress. The suction area increases. A vacuum develops, whereby the pump independently self-primes.

On the pressure side, the wings are squeezed together. Gaps become smaller and are emptied.

All Impeller pumps are delivered in portable models (up to size IP 03) and mobile models. All pump parts that come into contact with the products being pumped are made of rust-proof stainless steel, material no. 1.4301/304 electrolytic ally polished model. As standard, pumps can be delivered with a by-pass or without a by-pass adjustment.
