A washer including a plurality of spray jets and nozzles is disposed within a washing chamber for spraying washing and rinsing fluids into the washing chamber. Conduits supply the washing and rinsing fluids to the jets. A sump at the bottom of the washing chamber collects the washing and rinsing fluids sprayed from the jets. A pump re-circulates the washing and rinsing fluids from the sump to the conduits and nozzles. The washer is further comprised of a fluid displacement device centrally disposed within the sump. A fluid displacement device is dimensioned to displace fluid within the sump and to define a generally annular sump chamber surrounding the fluid displacement device that communicates with the pump.
