Liquid Ring Vacuum Systems

CDR Pumps is an official supplier of Travaini vacuum systems in the UK. We supply genuine Travaini pump packages across the UK with full technical support from our specialist engineers. 

Liquid ring vacuum pumps handle high volumes of vapours, condensables and liquids without affecting performance or reliability. The service liquid – water or other liquids, oils or solvents – can be selected to suit almost any application. Available in single and two-stage units.

Pompetravaini’s complete vacuum systems include a liquid ring vacuum pump, an air-liquid cyclone separator and a heat exchanger, all mounted on a compact skid for easy installation. For water-based applications, the system can also be configured to operate as a compressor, delivering pressures of up to 2 bar with optional upgrades
