Liquid Ring Vacuum Pumps

Liquid Ring Vacuum Pumps are rotary positive displacement pumps where a rotor churns a ring of liquid to form a compression chamber seal. The pump technology was originally patented by Lewis H. Nash in 1905 and the pumps are still manufactured by the Nash Engineering company (now known as Gardner Denver Nash).
