Liquid Ring Vacuum Pump
Liquid Ring Vacuum Pump
The working principle of a liquid ring pump is based around a pump body and an eccentric rotor. As the rotor spins, the seal liquid inside the pump forms a rotating "liquid ring" on the inner surface of the body. NASH liquid ring vacuum pumps feature three product sizes including small capacity, medium capacity, and large capacity liquid ring pumps.
➤ Small Capacity Pumps
NASH small capacity liquid ring vacuum pumps feature monoblock or lantern designs. These designs deliver the benefits of a simple, compact, and economical installation. Our small capacity liquid ring pumps are available in a variety of materials including cast iron and stainless steel and are ideal for use in a vast range of general industrial processes.
