Save time and money while washing small parts in high volumes

Arnold Machine rotary drum and rotary basket parts washers allow your facility to continuously wash small-sized parts in high volumes. We design, engineer, and build our parts washers to endure extremely dirty operating environments while outlasting the competition by decades.

We manufacture our rotary drum parts washers in our 75,000-square-foot facility in Tiffin, Ohio. No two parts cleaning applications are the same—this is why we work closely with you to custom-design and engineer the ideal rotary drum washer to solve your toughest parts washing challenges


Rotary drum cleaning systems are ideal for high-volume, continuous in-line cleaning of small parts. To operate, fill the drum with an aqueous solution, solvent, or abrasive materials and place the dirty parts inside.

The rotating drum has an internal helix designed to advance and tumble parts through one or multiple stages. As the drum rotates, it agitates the parts and efficiently and effectively removes dirt, grease, or other contaminants.


Rotary drum parts washers are ideal for a wide range of applications, including:

  • Automotive components
  • Aerospace parts
  • Electronics manufacturing
  • Hardware (nuts, bolts, etc.)
  • Metalworking and machining
  • Paint and ink removal
  • Ammunition
  • Stampings
  • Plastic, polymer, and stamped parts
  • Bearings and bushings


Drum sizes vary from 12 to 72 inches, and we can also customize the height and pitch of the internal helix to meet the requirements of part geometry and the desired feed speeds. Rotary drum washers allow for spray, immersion, or both and can include wash, rinse, dry, oil separation, and other advanced features.

Standard features include:

  • Heavy gauge stainless steel tanks
  • Welded pipe joints for leak-free operation
  • Heavy-duty, reliable components
  • Made in the USA quality


Arnold Machine rotary drum washers offer many options and configurations to solve your toughest precision cleaning challenges.

Multi-stage configuration (wash, rinse, dry)—A 3-stage system is the most common, but if the soap used in the wash stage doesn’t require a rinse, you can get by with a 2-stage (cleaning and drying) system.

Dual drums for part segregation—These work well if you need to clean multiple separated parts simultaneously. They’re more cost-effective in the long run because the parts washer can wash/rinse/dry separate parts in separate drums but only utilize one wash cabinet, one wash pump, one rinse pump, one blower, one wash tank, one rinse tank, etc.

Immersion or spray systems—Immersion is an ideal solution if the parts you need to wash would benefit from being soaked for some time before being sprayed to help loosen their soil load. If that isn’t needed, then just a spray will be sufficient.

Oil separation—We always option an “oil coalescer” on all of our quotations. Our oil coalescers help separate the removed oil from dirty parts from the wash solution. This ultimately prolongs the bath life and reduces the number of times you need to drain and clean the wash tank. You’ll wind up saving even more time and money.
