Abstract

An engine pump assembly (1), particularly a main coolant pump, composed of a housing (4) of a rotary pump with delivery elements arranged therein, a heat barrier part (6), a motor part (5) which drives the delivery elements, and force transmitting connecting elements (7) between a housing flange (8) of the housing (4) of the rotary pump and a flange (21) of the engine part (5). For faster and more reliable assembly and disassembly, the housing flange (8) is provided with receptacles (12) over at least half of its periphery for the arrangement of screw heads (13, 15) of the connecting elements (7), which screw heads (13, 15) are held in a bayonet-like manner in the receptacles (12).
