KMLR Series single-stage, liquid ring vacuum pumps feature rugged construction. The axial-flow design is said to enable efficient, vibration-free operation in the vacuum range from 760 to 25 Torr, with capacities up to 280 cfm. The pumps don’t have any metal-to-metal contact between rotating and stationary elements and don’t use oil for lubrication or sealing, the company says. The units use mechanical seal and O-ring gaskets.
