Abstract: An apparatus for separating oil and debris from an aqueous fluid disposed in a bath includes a separator assembly including a tank defining an interior chamber, and a separator coupled to the tank, the separator including an inlet in fluid communication with the bath and an outlet. A rotary positive displacement pump has a pump inlet in fluid communication with the separator outlet and a pump outlet in fluid communication with the bath.

Abstract: A multipurpose parts washer used to remove grease, oil, and dirt from mechanical parts may include an automatic cleaning portion, a first cleaning chamber for spraying parts, a second cleaning chamber for soaking parts, and a manual cleaning portion. A controller for selectively operating the automatic cleaning portion may also be included. Displays may be connected to the controller to illustrate various states. All portions use cleaning solution from a single pump, a reservoir portion to collect and store a volume of cleaning solution and debris from the washing process, and a thermal energy source for heating the cleaning solution.

Abstract: A multipurpose parts washer may include an automatic cleaning portion, with a first cleaning chamber for spraying parts, a second cleaning chamber for soaking parts, and a manual cleaning portion. Cleaning solution may be disposed in a reservoir of the first cleaning chamber at a reservoir level and in the second cleaning chamber at an agitation level that is above the reservoir level. The manual cleaning portion may be configured as a sink that is movably connected to the automatic cleaning portion to provide selective access thereto. A first thermal energy source may be used to heat the cleaning solution to a first temperature for the second cleaning chamber and the manual cleaning portion and a second thermal energy source may be used to heat the cleaning solution to a spray temperature greater than the first temperature for the first cleaning chamber. The multipurpose parts washer includes three cleaning portions.

Abstract: The disclosure is directed to a method for servicing a parts washer having a movable sink and movable lid connected to a support frame to facilitate replacement and maintenance of a cleaning solution reservoir. A pump is also pivotally connected to the sink to lift the pump during replacement and maintenance operations.

Abstract: The present disclosure relates generally to a movable aqueous- and solvent-based parts washer used to wash grease, oil, dirt, and other debris from mechanical parts using an cleaning solution, and more particularly, to a parts washer with a movable sink and movable lid pivotally connected to a hollow housing for facilitating the access within the housing for the replacement and maintenance of a cleaning solution reservoir. The third-generation washer is made of molded reinforced polymer in a shell configuration around a tilting reservoir. A pump is also pivotally connected below the sink to retract the pump during change operations of the cleaning solution reservoir. The device includes a molded sink with basin and reinforced pan with an interface to control the release of fumes between the sink and the pivoting lid.

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.

Abstract: The present disclosure relates generally to a multipurpose parts washer used to remove grease, oil, and dirt from mechanical parts, and more particularly, to an apparatus for washing parts within a single housing having an automatic cleaning portion, with a first cleaning chamber for spraying parts, a second cleaning chamber for soaking and agitating parts, and a manual cleaning portion. The multipurpose parts washer includes three cleaning portions. All portions use cleaning solution from a single pump, a reservoir portion to collect and store the important volume of cleaning solution and debris from the washing process, a single controller interface operated from a display, and a thermal energy source for heating the cleaning solution.

Abstract: An oil-water and oil emulsion separation system using a plurality of transport vessels as the separation tanks. The containers or tanks are arranged in series with sludge or oil removed first and thereafter remaining oil is removed and finally a relatively pure aqueous solution is returned to the system. The unit is useful with parts washers or any apparatus with which water is contaminated by free oil or sludge. A floating skimmer is placed in the user's sump and a vacuum draws this into a series of containers in which it is processed and in which sludge and oil are successively separated. A positive displacement pump is used. A manifold having vacuum relief valves for at least one container is also provided. In one embodiment, flow restrictors are placed in at least one manifold.
