PROBLEM TO BE SOLVED: To provide a pump housing assembly mitigating a defect that continuous turbulent flow in a level difference or in a clearance accelerates wear of a wear part if the wear is locally generated, and the local wear wears the whole nesting in the worst case, which exposes and wears a casing which traps pressure inside. SOLUTION: The pump housing assembly is equipped with the pump casing 12 and the nesting 20. The pump casing includes at least two components 13, 14. These components can be connected to each other in an assembled state. In the pump housing assembly, the pump casing is equipped with a front side part and a rear side part arranged in a back-to-back manner. In the assembled state, the two components of the pump casing have a common joint area arranged in one or two surfaces passing through the front side part and the rear side part of the pump casing.
