A pump (10) including an electric motor (12) mounted in a motor casing (14), and a rotatable pumping member (16), the pumping member (16) when rotated by the motor (12) pumping a first fluid, there being a first fluid flow path (A) for the first fluid from a high pressure side (16a) of the pumping member (16), into the motor casing (14) to cool the motor (12), and to a low pressure side (16b) of the pumping member (16), the pump (10) further including a heat exchanger located between a wall of the motor casing (14) and a heat load (22), the heat exchanger including a second fluid flow path (B) for a second fluid so that in use, heat is exchanged between the first and second fluids. <IMAGE> |
