Coaxial Flexible Impeller Transfer Pump

The coaxial flexible impeller transfer pump is a self-priming positive displacement pump operating at low speed, particularly suitable for transferring dense liquids and liquids containing suspended solids.

The pump is equipped with a flexible rubber impeller that transfers the liquid continuously without altering its characteristics.

It is widely used for transferring wine and must, including must with grape residues, as well as beer, fruit juices, milk and yogurt. It is also used in the oil sector and in chemical and pharmaceutical applications.

The coaxial stainless steel pump has a food-grade rubber impeller mounted directly on the electric motor. All versions are supplied with a reversing switch for reversible flow.
