Abstract
A pump including an electric motor mounted in a motor casing, and a rotatable pumping member, the pumping member when rotated by the motor pumping a first fluid, there being a first fluid flow path for the first fluid from a high pressure side of the pumping member, into the motor casing to cool the motor, and to a low pressure side of the pumping member, the pump further including a heat exchanger located between a wall of the motor casing and a heat load, the heat exchanger including a second fluid flow path for a second fluid so that in use, heat is exchanged between the first and second fluids.
