ABSTRACT:
A parts washer including magnets located near a pump inlet to collect metallic particles suspended in the cleaning fluid; a casing to protect the pump mechanism from impact during handling; the pump oriented horizontally to take advantage of the separation of the cleaning fluid in successive vertical layers; two liquid level sensors to measure the level of the cleaning fluid in the reservoir; an evaporation control plate located at the interface between the reservoir and the receptacle of the reservoir to confine the vapor portion of the cleaning solution; protective handlebars placed next to the controls of a control module to protect the device from impact; and a pump motor control to provide a low flow rate of cleaning fluid using a pump without a variable regulator.
