PARALLEL FLOW PUMP
An improved parallel flow pump is provided. The improved parallel flow pump includes clearance for tooling, nuts, and bolts, and further provides smoothed, contoured surfaces and one or more turning vanes to improve the top-to-bottom velocity distribution in the discharge manifold into which the pump flows.
1 . An improved flow parallel flow pump comprising:
a pump housing, wherein the pump housing comprises a pump inlet and a pump outlet, and wherein the pump inlet is fixedly attached to a first end of the pump housing, and wherein the pump outlet is fixedly attached to a second end of the pump housing;
a raised volute, wherein the raised volute extends from the pump outlet to a cylindrical passage, and wherein the cylindrical passage extends from the raised volute to a intake chamber; and wherein the intake chamber extends from the cylindrical passage to the pump outlet; and
a plurality of turning vanes.
2 . The improved flow parallel flow pump of claim 13 , wherein the plurality of turning vanes are positioned within an interior area of the pump housing.
3 . The improved flow parallel flow pump of claim 13 , the plurality of turning vanes are disposed within the raised volute.
4 . The improved flow parallel flow pump of claim 13 , wherein the plurality of turning vanes comprising:
an elongated body;
a leading edge, wherein the leading edge is disposed within the raised volute; and
a trailing edge, wherein the trailing edge is positioned at the pump outlet.
5 . The improved flow parallel flow pump of claim 13 , wherein the plurality of turning vanes are positioned such that the plurality of turning vanes comprise a plurality of fluid paths.
6 . An improved parallel flow pump comprising:
a pump housing, said pump housing including:
an inlet;
an outlet;
an exterior surface extending between said inlet and said outlet;
an inlet flange extending generally perpendicularly from said surface at said inlet; and
an outlet flange extending generally perpendicularly from said surface at said inlet; and
a clearance feature near said inlet and outlet flanges.
7 . The improved parallel flow pump of claim 18 wherein said clearance feature comprises an area of indentation within said exterior surface of said pump housing.
8 . The improved parallel flow pump of claim 19 wherein said clearance feature is sized and shaped to accommodate the outer surface of a socket.
