Volumetric Flexible Impeller Pump with Mechanical Variator

The volumetric flexible impeller pump with mechanical variator is a self-priming pump with a low impeller rotation speed and is particularly suitable for transferring liquids that are dense and/or contain suspended solids.

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

This volumetric pump is widely used for transferring wine, must (even with grape residues), and in the oil sector and, more generally, in the food industry, especially for beer, fruit juices, milk and yogurt. It is also useful for feeding a filter.

It is additionally used in the chemical and pharmaceutical fields.

The electrical system is external, with motor overload protection.
