Part Washing Equipment

Immersion-Ultrasonic Parts Washers

Thorough Cleaning for Complex Parts and Difficult-to-Reach Features

ALMCO Immersion Parts Washers provide a highly effective cleaning solution for components that benefit from soaking, agitation, or ultrasonic cleaning. Unlike spray-based systems, immersion washers completely submerge parts in a cleaning solution, allowing fluid to reach internal passages, blind holes, recesses, and complex geometries that can be difficult to clean through conventional washing methods.

Designed for aqueous cleaning applications, ALMCO immersion washers are ideal for removing oils, coolants, chips, particulate, and manufacturing residue from machined, cast, fabricated, and assembled components. Available with agitation and ultrasonic cleaning technology, these systems deliver exceptional cleaning performance while supporting both batch processing and automated manufacturing environments.

SYSTEM DETAILS

Wash Basin

How It Works

The machine is built to heavy industrial standards with a 12-gauge stainless steel tank bottom and 14-gauge stainless steel tank walls.

Ultrasonic cleaning is a result of high frequency sound waves introduced into a cleaning liquid by means of a series of “transducers” mounted to the cleaning tank. The sound travels throughout the tank and creates waves of compression and expansion in the liquid. In the compression wave, the molecules of the cleaning liquid are tightly compressed together. Conversely, in the expansion wave, the molecules are rapidly pulled apart. The expansion is so dramatic that the molecules are ripped apart, creating microscopic bubbles. The bubbles are not seen by the naked eye since they are so small and exist for only a split second of time. The bubbles contain a partial vacuum while they exist. As the pressure around the bubbles becomes greater, the fluid around the bubble rushes in, collapsing the bubble very rapidly. This violent collapse, combined with the liquid jets velocity, provides a very intense cleaning/scrubbing action in a minute area. This scrubbing action exists throughout the cleaning bath. When utilizing detergents designed for a specific application, a synergistic cleaning action is produced.

Pneumatic Lift

Pushbutton control activates the unit’s Pneumatic System, which automatically lowers the workload into the immersion chamber while simultaneously closing the tank cover before agitation begins. Agitation stops when the cleaning cycle is complete, and the cover opens automatically as the workload rises up and out of the solution, flush with the top of the cabinet for draining and product removal.

Wash Metering

Agitation System

Ultrasonic agitation / immersion washer uses a heavy-duty gearmotor drive to move the product to be cleaned through 60 four-inch vertical strokes per minute. Ultrasonic energy combined with the surging action created by the agitation cleans the product inside and out.

PW Control Panel

Electrical Controls

Electrical controls are housed in a Hoffman (or Saginaw) brand NEMA 12 enclosure mounted on the side of the wash cabinet (as room permits, otherwise enclosure is free standing). Components within the enclosure are finger-safe and are Allen-Bradley brand unless noted otherwise. Components include a main disconnect switch, Littelfuse fuse holders and branch circuit fuses, terminal strips, a
G.E. (or equal) transformer to provide a 115 Volt control circuit, master control relay, Minarik 90 Volt DC motor controller (for the turntable drive), heating system contactor, and an IEC-style motor circuit protector with thermal overload and short circuit protection.

An equipment power on pushbutton, an emergency stop pushbutton are provided on the front door of the main electrical enclosure, along with the reservoir heating system’s Watlow digital temperature controller. Machine start/stop controls are provided on the side of the enclosure facing the front of the machine. Buttons and lights are Allen-Bradley brand.

The machine is wired per NEC (NFPA 70) and NFPA 79 electrical standards, ready for connection to your electrical service.

Auto Lid

Automatic Lid

Pushbutton control activates the unit’s Pneumatic System, which automatically lowers the workload into the immersion chamber while simultaneously closing the tank cover before agitation begins.

Bag Filtration

Consists of a floor-mounted bag filter housing and a filter bag rated at 50 microns. The 4″ diameter by 12″ tall stainless-steel housing is over-sized for less frequent filter change-outs, and the unit is piped between the spray pump and the spray nozzles in the Washer. The housing includes a stainless-steel internal basket for holding one filter bag, and the hinged stainless-steel cover is held in place with three eyebolts. Inlet and outlet pressure gauges are also provided.
