Flexible Impeller Transfer Pump with Mechanical Speed Variator

The flexible impeller transfer pump with mechanical speed variator is a self-priming pump operating at low impeller speed and is particularly suitable for transferring dense liquids and liquids containing suspended solids.

It is equipped with a flexible rubber impeller that transfers the liquid continuously without altering its characteristics, together with a mechanical indicator of the operating speed.

The pump is widely used for transferring wine and must, including must with grape residues, as well as oil, beer, fruit juices, milk and yogurt. It can also be used for feeding a filter and in chemical and pharmaceutical applications.

The electrical system is external and equipped with motor overload protection.
