| | | KLRC liquid ring vacuum pumps are ideally suited for pumping wet mixtures and even slugs of liquid. They are available in standard, all iron construction (no yellow metals) and 316 stainless steel. Liquid ring pumps often require water-cooling, but air-cooling systems are available. Complete engineered system solutions, including instrumentation, controls, piping and valves specification; self-contained liquid recovery and recirculation are also available. KLRC liquid ring vacuum pumps can pull down as low as 4 Torr (5.3 mbar a). However, low-pressure performance is limited by the vapor pressure of the sealing liquid, which can be water, oil or process liquids. Typical Applications: Chemical and Pharmaceutical Processing Vapor Recovery Deaeration Crystallizers | | A & T Series Liquid Ring Vacuum Pumps AF single-stage "A" series and two-stage "T" series vacuum pumps are simplistic in design, rugged in construction and built to run in the most severe of industrial conditions. With no metal-to-metal contact, it is not unusual for these pumps to run in 24/7 operation for years without maintenance. These "abuser-friendly" pumps are vibration-free and environmentally friendly, with no oil used for lubrication, and no oil discharged to atmosphere. Complete, self-contained systems, including liquid recovery and recirculation, are also available. "A" series single-stage pumps pull down to 29" Hg (25 Torr [33 mbar a]); "T" series two-stage pumps pull down as low as 4 Torr (5.3 mbar a). However, low-pressure performance is limited by the vapor pressure of the sealing liquid, which can be water, oil or process liquids. Typical Applications: Filtration Solvent Distillation/Vapor Recovery Sterilization Degasifiers Extruders Deaeration Evaporators | | |
| | | Dry Screw Vacuum Pumps The SDV dry screw vacuum pumping operates without oil or water in the pump chamber, and with its straight-through design, the SDV can handle both condensable vapors and some solids without leaving residue. There is no metal-to-metal contact inside the pumping chamber, so wear is greatly reduced. The Kinney SDV dry screw pump suppliers is water-cooled, but self-contained air-cooled coolant recirculation systems are available. Typical Applications: Chemical and Pharmaceutical Processing Solvent Recovery Forming Crystallization Dry Etching Sputtering Vapor Recovery SDV pumps are variable-pitch, to increase efficiency, and lower temperatures. SDV pumps are also capable of full pumping speed from atmospheric pressure to 1 Torr (1.3 mbar a); however, the SDV can achieve ultimate vacuum as low as 0.01 Torr (0.013 mbar a). | | |
