Electric motors for belt drive and close coupled pressure cleaner pumps. Listed by rating and by how they mount, because both have to be right. A hollow shaft motor takes the pump directly on the motor shaft, a B3/B14 flange motor bolts to a flange on the pump, and an elastic joint motor drives through a coupling - they are not interchangeable without changing the pump end as well.

Single phase 240 V is the practical limit around 2.2 to 3 kW; above that you want three phase. Match the kW to the pump duty with some margin, and check the pole count if speed matters - a 4 pole motor runs near 1,410 rpm, which is what most low speed triplex pumps are built for. If you are replacing a motor on a working machine, take the rating plate details rather than measuring the frame.
