ABSTRACT:
A centrifugal pump of the pitot tube type is structured with axially stabilizing elements which assist in stabilizing the pitot tube assembly of the pump during high pressure operating conditions. The axially stabilizing elements include at least one seat member positionable to register against the discharge tube of the pitot tube assembly to keep the discharge tube in axial alignment and in a selected tension. The pitot pump may also include a pressure relief channel positioned to accommodate increased pressures which may arise from an o-ring failure in the sealing mechanism of the discharge assembly. The axially stabilizing elements reduce the occurrence of fretting and galling resulting from axial forces exerted on the pitot tube assembly and facilitate simplified construction and assembly of the inlet manifold to a discharge assembly or manifold. The cost of constructing and maintaining the centrifugal pump is thereby reduced.
