Hermetic: Liquid ring vacuum pumps in titan and Hastelloy

Monday, March 11th, 2013 von admin

LVP-1800The liquid ring vacuum pump is one of the workhorses in the chemical and petrochemical industry. The construction provides a nearly isothermal compression at comparatively low temperatures. Polymerisation and other undesirable reactions (thermal cracking, cakings) are largely avoided under these conditions. The ring consisting of liquid is used as tightening element desensitising the system against liquid hammers and drops in the gas flow handled, as they often are produced during extraction of inerts from condensers. The construction without touching and wearing parts makes our customers feel confident of reliable availability. A hermetically sealed design with magnetic coupling or canned motor does not only increase availability – since regular change of mechanical shaft seal is no more necessary – but also meets customers requirements in case of toxic gases and pumping liquids demanding “TA-Luft”.
