The new HydroPack series represents the best solution for compactness, efficiency and functionality in the installation of total recirculation liquid-ring vacuum pumps.


The pump is mounted on a single skid which acts as an air-water separator and, thanks to an integrated and externally powered heat exchanger, allows the maintenance of extremely low and constant operating temperatures.
The level of the service liquid on the center line of the pump guarantees safe start-up and smooth operation in all conditions, even under low vacuum.
This system is also characterised by a long self-sufficiency, due to the high quantity of water that it can contain.
