Parts Washers

Power Wash: The Superior Parts Cleaning System

A jet spray washer cleans by flooding the parts with lukewarm chemical solution depending on high detergent concentration as the primary cleaning mechanism. In the power wash process, the parts are blasted with a low concentration of detergent using hydraulic impact force and high-temperature as the primary cleaning mechanisms.

A parts washer utilizing the Power Washer Process cleans using a very low concentration of cleaning chemical. The low concentration enables the cleaning solution to last longer before it becomes supersaturated and requires disposal. Additionally, a low concentration of detergent rinses off the parts easily, minimizing rinse cycle requirements that save fresh water and shorten cycle times.

A final key factor used in the Power Washer Process is an oscillating solution delivery system that is non-synchronous to the rotation of the turntable. This oscillating system assures that the blasted solution reaches all areas of the wash load that are otherwise blinded by stationary manifolds used in jet spray washers. Overall, the Power Wash Process is superior to jet spray washing for faster more thorough parts cleaning cycles while minimizing cleaning chemical use and waste generation. All StingRay Parts Washers utilize the Power Wash Process.

The nozzles in Jet spray washers aim at the center of the turntable so that a single strike angle hits the same surfaces throughout the wash cycle. By comparison, at the heart of every StingRay Parts Washer lies the patented, non-synchronized, oscillating spray manifold system that blasts parts from a different angle each time the part passes on the rotating turntable, providing thousands of strike angles during each wash cycle.

Jet Spray Washers operate at low flow and moderate pressure with an average of 50 PSI at 2.8 GPM per nozzle and velocities under 90 ft/sec. Difficult soils and shorter wash-cycle requirements demand higher impact pressure and higher Power Density* (amount of cleaning energy in horsepower per cubic foot of cabinet volume).

StingRay offers a wide selection of pumps to provide a Power Washer equipped with enough power to do the job. (Compare StingRay Washers to other manufactures equipment) For example, the StingRay model 6075 (60” diameter turn table with 75” work height) equipped with a 70 hp Duplex pump system, commonly used for tough soil removal, has a Power Density of .57 (hp/ft³). This is enough power to remove carbon deposits from cylinder heads. (Note: The StingRay 70 hp Duplex pump system delivers 431 GPM which is more than 3,500 pounds of hot solution every minute blasting the parts with 190 PSI.)

Important distinction: Jet Spray Washer performance data is typically provided from the pump curves, provided by the pump manufacture, and does not account for the substantial suction, discharge and transitional losses that occur in the plumbing system. Losses that consume energy and reduce power available for parts washing greatly reduce the ability to clean parts. StingRay pump performance data is accurately measured and reported at the parts washer’s nozzle tips.
StingRay Power Wash technology combined with our high-efficiency pumping systems and high-output heating systems deliver faster cleaning cycles and more thorough cleaning. The StingRay Parts Washer is environmentally safe with a closed-loop, zero discharge design to meet EPA and OSHA regulations. StingRay provides the complete solution for your cleaning needs: parts washer, detergent, and technical support.
