Introduction

The 2BEC TW0-STAGE LIQUID RING VACUUM PUMP 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 TW0-STAGE LIQUID RING VACUUM PUMP’s axial suction and discharge ports are exposed to the void but separated by the impeller blades and the ring of liquid. As the process gas or vapor is drawn into the pump through the suction port, it is trapped between the impeller blades and the liquid ring. The rotating blades enter deeper into the liquid ring progressively reducing the entrapment space, compressing and then exhausting 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

Features

●Impellers positively locked to shaft

●Reliable mechanical seals for high-integrity sealing and low shaft friction

●Center-anchored tie rods allow access to either end of the pump without total disassembly

●Precision casting and CNC machining eliminates the need for body gasketing (process dependent)

●Replaceable end plates

●Clearance adjustments via shims
