Abstract
The spiral housing of a centrifugal pump which forms a unit with an electric motor and consists of two parts flanged together by screws evenly distributed over its circumference. The axis of rotation on the impeller forms a 45 degree angle with the axis of the inlet port and the axis of the outlet port. The two ports of the spiral housing can be mounted in at least two positions. In the first position, the axis of the outlet port forms a 90 degree angle with the axis of the inlet port forming a centerline pump. In the second position, the axes of the ports form a 180 degree angle forming an inline pump.
