StingRay Parts Washer Features

The StingRay Parts Washer is a feature rich industrial parts cleaning system. Enclosed in a steel or stainless steel cabinet, the aqueous based washer cleans in automatic cycles. The parts wash load is placed on a powered turntable that retracts fully from the enclosed cleaning cabinet when the door opens.  The pump system forces solution through oscillating nozzles that blast the parts load from continuously varied angles of attack.  Completing the parts washer are the solution level management system, temperature controlled solution heating system, pump suction filter, safety devices, and single point connection electrical system. Optional rinse, steam exhaust and blow-off cycles are easily included per your needs.  A number of optional solution maintenance devices – oil skimmer, sludge scraper, surface scraper, in-line filtration extend solution life. The StingRay Parts Washer is environmentally safe with a closed-loop, zero discharge design to meet EPA, OSHA regulations and Green Technology.

  • PUMP MOTORS: TEFC with Class F Insulation and NEMA MG-1 Rated, with 1.15 to 1.25 Service Factors, Ball bearings, continuous duty Industrial Grade and rated for 20 starts/hour without overheating.
  • PUMP SUCTION STRAINER: Perforated 16 ga sheet steel strainer, located at front of machine reservoir for ease of service and cleaning, designed for 2 times rate flow at 50% plugged condition.
  • SUCTION STRAINER: Pore size of Pump Suction Strainer is slightly smaller than orifice diameter of nozzles, so particles that pass through the Suction Strainer will also pass through the nozzles to minimize clogging.


StingRay Power Blast Manifold SPRAY  MANIFOLD: Patented oscillating manifold system blasts from the top down, bottom upward, and across the cabinet. As the wash load rotates, the Manifold oscillates on its vertical axis, making a 40-degree sweep and return every 15 seconds, throughout the wash cycle. (VIDEO) Movement of the Manifold is not synchronized to rotational speed of the turntable so each surface of wash load is blasted from a different angle each time it passes the Manifold. System is driven by a TEFC gear motor with heavy-duty crank arm linkage system featuring mono-ball bearing construction for long service life. Unions or flanged connections make servicing easy.

NOZZLE SYSTEM: High impact stainless steel machined V-Jet and “0” degree patterns, aimed and spaced for overall coverage and set so each nozzle blasts on its own plane and cannot intersect with, or deflect, other nozzles in system.

StingRay Turntable DriveTURNTABLE & DRIVE SYSTEM: A heavy steel turntable on sealed bearings is driven by a thermoplastic sprocket that positively engages the turntable teeth to prevent slippage. The sprocket is powered by a TEFC gear reduction motor with steel gears and ball bearings mounted externally of the wash cabinet. The drive system is protected by a clutch overload for reliability and long service life should the turntable jam from parts that may fall. The turntable is constructed of heavy bar steel with hook and eye attachments and a rim that provide for easy anchoring of part wash loads.
