Liquid Ring Vacuum Pumps

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

Liquid ring vacuum pumps deliver consistent, reliable performance and are available in a wide range of metallurgies and sealing options to suit specific applications, including use in hazardous, flammable and explosive areas. Their versatility and reliability make them widely used in facilities of all sizes and across many industries.

Available as single- or two-stage liquid ring units, these pumps can handle high volumes of vapours, condensable gases and liquids without compromising performance or mechanical reliability. The service liquid – water or other liquids, oils or solvents – can be selected to suit almost any application. When clean water is used, the aspirated air is ‘washed’ free of contaminants such as oil, carbon or plastics.

Manufactured to ISO 9001 standards, Pompetravaini’s liquid ring vacuum pumps are designed for simplicity and reliability. Fewer components simplify maintenance, while minimal moving parts eliminate metal-to-metal contact, significantly reducing vibration, noise and wear.
