Flexible Impeller Transfer Pump with Pulley Drive

The flexible impeller transfer pump with pulley drive is a self-priming pump operating at low RPM, particularly suitable for transferring dense liquids and liquids containing suspended solids.

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

It is suitable for transferring wine and must, including must with grape residues, as well as oil, beer, fruit juices, milk and yoghurt. It can also be used in chemical and pharmaceutical applications.

The pump is built entirely in AISI 304 stainless steel and mounted on a stainless steel trolley. It can be used for different transfer operations, including destemmed grapes and feeding a filter. The electrical system is separate and equipped with a motor protector in compliance with CE standards.
