Kinney® KLRC™ liquid ring vacuum pumps are ideally suited for pumping wet mixtures and even slugs of liquid. KLRC pumps are available in standard, all iron construction (no yellow metals) and 316 stainless steel.
Complete engineered system solutions, including instrumentation, controls, piping and valves; self-contained liquid recovery and recirculation are also available. KLRC liquid ring vacuum pumps can achieve vacuum of 4 Torr (5.3 mbar a). Please note that final pressure is limited by the vapor pressure of the sealing liquid, which can be water, oil or process liquids.

The KLRC is a non-pulsating vacuum pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid. The impeller forces this sealing liquid to the periphery of the pump casing, where it forms a moving ring of liquid around a center void.
The impeller shaft is mounted above the centerline of the casing; while the blades, although rotating concentrically, are located eccentrically with respect to the casing and the ring of liquid. The pump's axial suction and discharge ports are exposed to the void but separated by the impeller blades and the liquid ring.
The rotating blades enter deeper into the liquid ring, progressively reducing the entrapment space, compressing and then exhuasting the gas through the discharge port. The liquid ring acts like a liquid piston, meaning the entire pumping operation is accomplished without vanes, valves, pistons or any metal-to-metal contact.
