Because of the increased liquid hold-up capability, this type is especially suited for high gas volume fractions (GVF >97 %). Extended dry-running periods can be achieved, as it might be necessary for handling a gas cap. Numerous applications as wet-gas compressor, e.g. with liquid loading of gas well, show the excellent technical design of this pump.
As a standard the maximum allowable working pressure is 100 barg (acc. to ANSI B16.5 600 lbs.). However higher pressure ratings are possible and already executed.
