A combined electric motor and pump unit has a single casing (4) having an electric motor with stator (1) and rotor (2) and a pump with fluid reaction member (3) united with so as to form part of the rotor (2). The member (3) is located in a principal transmission path for liquids to be pumped and a secondary transmission path for such liquids is provided by the clearance between the stator (1) and the rotor (2). The electrical windings (8) of the motor are insulated with materials which are inert to the pumped liquids, PTFE wrappings being preferred. |
