The radial piston pump for pumping water, especially pure water, comprises a pump housing, a central drive mechanism and a surrounding pump mechanism which has a plurality of piston-and-cylinder units radially oriented and distributed about its circumference. Inlet and outlet valves for individual cylinder chambers are located in the vicinity of the piston-and-cylinder units. The drive mechanism is located in a housing chamber which has an oil sump. The housing chamber is surrounded by a cooling device comprising a plurality of gaps and ducts for conducting water to the inlet valves which are provided with a suction intake fitting for admitting water.
