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
