Liverani VA Series Mechanical Variable Speed Flexible Impeller Pumps
Liverani VA Series Mechanical Variable Speed Flexible Impeller Pumps
The VA series fits a mechanical speed variator to the flexible impeller pump head, letting your cellar or crush pad crew dial the flow rate up or down on the fly with a simple hand control, no electrical inverter, no programming, just a mechanical dial for instant, reliable speed adjustment.
This makes the VA a great fit for wineries who move between very different jobs on the same pump through the day; gentle, slow handling of must and whole berries in the morning, faster bulk wine transfer in the afternoon; without needing to swap pulleys or motors. It's a simpler, more rugged alternative to an inverter-driven pump for crews who want mechanical reliability over electronics on the crush pad.
Ideal for: wineries wanting on-the-fly flow control without electronic inverters: simple, robust, mechanical speed adjustment for varied vintage tasks.
