Liverani INV Series Inverter-Driven Flexible Impeller Pumps

Liverani INV Series Inverter-Driven Flexible Impeller Pumps

For wineries wanting the finest control over flow rate, the INV series pairs the flexible impeller pump head with a frequency converter (inverter) drive, giving stepless, precise electronic speed control from a very low crawl right up to full rated flow, all from a simple control panel.

This is the pump for delicate, high-value transfer work where flow rate really matters: filling barriques, gentle must handling straight off the crusher-destemmer, or metered transfer into presses and small-batch fermenters. The inverter drive also protects the motor and driveline from strain during start-up and speed changes, and pairs well with Liverani's barrel-filling gun kit and control panel accessories for automated, hands-off filling. Available across the full size range, including the high-volume Double 2Q/2H twin-head trolley units for big-vintage throughput with full electronic speed control.

Ideal for: wineries wanting precise, electronically controlled flow rates for barrel filling, delicate must handling, and metered transfer work.
