ABSTRACT:
A parts washer (5) for cleaning mechanical parts with a liquid cleaning solvent includes a sink (7) mounted upon a reservoir (8). The sink has a bottom wall (10) in which a filter cartridge opening (20) is defined for removably receiving a filter cartridge (80) depending downwardly toward said reservoir and mounted upon said bottom wall. Pump (41) draws liquid cleaning solvent from reservoir (8) and circulates the liquid cleaning solvent into sink (7) and back into reservoir (8). Hose (50) mounted in sink (7) may be connected directly to filter cartridge (80), and pump assembly (41 ) is operated so that liquid cleaning solvent is circulated directly, under pressure, into filter cartridge (80) for clarifying and reclaiming the liquid cleaning solvent in order to maintain its cleaning efficiency and prolong its service life.
