Diaphragm Vacuum Pumps, Chemical Resistant

Sri Vishnu Pumps Mfg Co offers chemical resistant Diaphragm vacuum Pumps, which are the best-suited oil free vacuum option for laboratory and pilot scaled application. Typical applications for chemical resistant diaphragm pumps include evacuating chemically aggressive gases and vapours from such equipment as rotary evaporators, vacuum drying cabinets and centrifugal concentrators. Most importantly, diaphragm pumps are oil-free, for vastly reduced service demands compared with oil-sealed pumps. They eliminate the water waste of water-jet aspirators, and the contaminated waste-oil disposal of rotary vane pumps. The diaphragms are available in various options of materials like EPDM, neoprene, viton and Teflon coated neoprene rubber. These vacuum pumps are available in the range of 15 LPM to 33 LPM generate a maximum vacuum of 30 Torr. Chemical resistant vacuum pumps are supplied with 3-phase flameproof motors also.
