ABSTRACT:
A pumping apparatus, more especially for fluid materials containing entrained gas pockets, comprises a single entry centrifugal impeller pump and means for maintaining a reduced pressure on the side of the impeller opposite said single entry to the pump. The pump impeller may have gas evacuation passages extending through the impeller disc from orifices located on the low pressure side of the impeller blades. The pumping apparatus preferably includes a liquid chamber communicating with the pump casing on said opposite side of the impeller, means controlled by the liquid level in said chamber for connecting the latter either with a vacuum source or with atmosphere, and means responsive to atmospheric pressure within said chamber for discharging liquid therefrom to the inlet side of the centrifugal pump.
