Standard Product System Operations


How the pump works


The Zeta L. Ring Vacuum Pump or Air Compressor has only one moving part- a balance rotor. Such simplicity is possible because all functions of mechanical pistons or vanes are actually performed by a rotating ring of liquid compressant.


The rotor transmits power to keep the ring of liquid rotating. However, the liquid tends to follow a path that conforms to the inside of the body. The body is cylindrical, but its axis is offset from the main rotor axis. Liquid compressants almost fills then partly empties each rotor chamber once each revolution.


The filling and emptying sets up a piston action. Inlet and discharge flow paths are separated by closed sections between the inlet and discharge ports.


Part of the liquid compressant passes out with the discharge gas and is removed in a mechanical separator. Make up is regulated automatically by orifices or by manual adjustment.
