ABSTRACT:
A unitary housing for a hydraulic unit such as tandem pump, having a plurality of rotating groups driven in one direction about a common axis by a source of rotary power having a pair of opposite end walls generally transverse to the common axis, a continuous side wall connecting the end walls, and at least two apertures in the side wall which allow the insertion of a rotating group into the housing. The housing can also include a first flange on one of the end walls for mounting the housing to a source of rotary power. A second flange can be included on the other end wall for mounting an auxiliary pump to the main hydraulic unit. Alternatively, if the second flange is the same size as the first flange, the housing allows the user to change the rotation of the tandem pump by spinning the housing end-for-end and without changing any internal components.
