3 Kinney Liquid Ring Vacuum Pumps and Systems DSIGN PRINIPL KLR Series The KLR 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. Suction Port enter Void Liquid Ring 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 ring of liquid. s 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.

6 v Series Series Liquid Ring Vacuum Pumps and Systems Series vacuum pumps consist of a shrouded motor rotating freely within an eccentric casing. entrifugal force acting on liquid within the pump causes the liquid to form a ring inside the casing. fixed port cylinder concentric with the rotor directs the gas into the suction ports. Gas is trapped between the blades by the liquid pistons formed by centrifugal force as the liquid recedes from the port cylinder. It is trapped at the point of maximum eccentricity and is then compressed by the liquid ring as it is forced radially inward toward the central port cylinder. fter each revolution the compressed gas and accompanying liquid are discharged. During the pumping cycle the gas is in intimate contact with the sealing liquid and compression is nearly isothermal. When handling saturated vapor-gas mixtures the liquid ring acts as a condenser, greatly increasing the effective capacity of the pump. Series Motor mounted single stage liquid ring vacuum pumps Mechanical Seals Shrouded Rotor O-Ring Sealing lose-coupled Design Flat power curve over entire vacuum range prevents motor overload Reduced stress on motor shaft and bearings creased water handling capability Replaceable Port ylinder xial Flow prevents heat build-up, extends life of mechanical seals ompact, close - coupled design eliminates need for interstate manifold or motor alignment avitation: Series pumps are not as susceptible to cavitation compared to flat plate design because the flow path through the pump is an axial flow. This flow allows the velocity through the pump to be unchanged and carries the air out effortlessly. 4
