Abstract
A truncated cone shaped pump support and fluid deflector is provided with a plurality of intake apertures in the wall thereof and the pump is supported in the wall below the upper side of the sloping wall so that the intake is uppermost and situated above the intake apertures. This maintains the pump and motor submersed in solvent at all times for cooling purposes and also provides self-priming characteristics to the pump. If the pump is switched on for too long a period, most of the fluid will be pumped to the sink of the parts washing machine thus starving the pump which, if fully exposed, can overheat and become damaged. Furthermore, with conventional pumps, if starved of fluid, air locks often occur which prevents the pump from operating correctly once liquid or fluid is restored thereto.
