A shell member for a pump housing of a centrifugal pump for cooperating with the rotatable impeller within said centrifugal pump comprising: (1) and annular shell provided with a throat having an actual throat area; (2) a tongue positioned along a peripheral portion of said shell; and (3) an outlet branch having a centerline; wherein the ratio of the radius of the shell at said tongue to the radius of the shell at right angles to a branch centerline is from about 0.8 to 0.9; and (4) said tongue being formed by a cut-water having a shape defined by the equation y=AxB, wherein x and y are coordinates defining points along the curve defined by the equation A=F(2B/w(B-1)), where B is a number between and including the numbers 2 and 5 and w is the width of the shell and F is a number between and including the numbers 1.0 and 0.5.
