Liverani INV Side Channel Pump

The Liverani INV Series are variable speed, inverter controlled side channel pumps with forced ventilation. These hygienic, stainless steel liquid ring pumps are trolley mounted and fitted with a mounted control panel and variable speed controller. The system doesn’t feature dry run protection and the pumps are close coupled with extra fan cooling on the motors instead of a gear box.

All the models of the INV side channel pumps are available as Three Phase, and are able to be run up to 60Hz offering a larger flow and head range than the standard 50 Hz units. Optional extras include:

1. Bi-directional radio controller instead of a wired unit which is water proof and can work up to a 100 m distance and is supplied with a charging station.

2. Supplementary 4-20 mA Connector

3. Timing System

4. Four Wheel Trolley
