VPM liquid ring vacuum pumps are high vacuum single stage type with vary port valve design. Besides simplicity and robustness, that are the main features, other advantages are as follows:
– wide range of applications
– high reliability
– possibility to handle almost any gas and vapour, even with liquid carry over residuals
– isothermal compression
– the only moving part is the impeller
– low maintenance
– oil-free operation
– low vibrations
– silent running
Single stage vacuum pumps for high vacuum in bare-shaft execution
Two stage vacuum pumps for high vacuum in bare-shaft execution or with supporting lantern
Single stage vacuum pumps for medium vacuum in bare-shaft execution
