Process Description and Dimensions

System Overview

The Sharpertek SK4000-2T is a drop-loading, single tank, industrial parts washer designed to a standard basket of parts at a time. ( Special sized baskets can be utilized.)  It is ideal for washing a wide variety of parts such as Aerospace, Bearing, Screw Machined, Machined Casting, and other Precision Components in a lean, cellular operation. The heat, ultrasonic action, and chemistry effectively remove oils, soils, dirt, chips and other by-products associated with manufacturing from ID and OD areas.

Process Description

At a cycle rate of up to 16 baskets per hour, the production rate is up to 14 cubic feet of parts per hour. Cycle time could be as short as 300 seconds.  Cycle times are variable and dependent upon soils and parts. Actual time cycles will be confirmed when part testing is conducted at Sharpertek in a SK4000-2T system.


Typical Sequence of Operation in a SK1000-2T



Duration (s)


Operator easily submerges baskets into machine, locks baskets, closes lid, presses Cycle Start Button



Wash pump rapidly fills process chamber,  high volume ultrasonic cleaning begins



Cleaning chemical is drained from processing tank



Clean water fills chamber to thoroughly rinse parts



Water is drained from processing tank



250-cfm re-circulating hot air dryer directs heated air at high velocity through multiple high volume slots



Operator opens lid, lifts baskets out of system



Total seconds for complete cycle (without optional ultrasonic wash or rinse)


Concept of Operation

The SK4000-2T can process up to 16 baskets an hour. Baskets fit into a working space of 24x24x24”DIMS.
A key feature is the system’s ability to keep the baskets submerged while simultaneously cleaning with heated solution and ultrasonic. This results in the best possible cleaning of complex-shaped parts by penetrating blind holes and cavities. The delivery of filtered Solution fully purges the cleaning chamber more than twice per minute, flushing soils and chips from the parts and process chamber, allowing even the most complex parts with blind holes to be effectively cleaned.

Years of Sharpertek innovation and development have resulted in proven, simple, and rugged design and construction elements that provide reliable operation.



The solution is continually filtered through out the cleaning process. The entire volume of the cleaning chamber is turned over more than twice a minute. This fast re-circulating turnover rate flushes away chips, soils and oils, always keeping fresh, clean solution in contact with the parts.


Filtered Rinse Water Discharge

Discharge solution is filtered during discharge process. Carbon filters are used to remove chemicals and oil that is dispersed in the solution.


Chip Removal

The cleaning chamber bottom is pitched from three sides for 100% quick drainage and chip removal. Chip strainer baskets are included for the tanks. All returning solution is filtered through these baskets to keep the storage tanks chip-free. Solution tanks do not have to be emptied to clean the baskets. To empty the chip baskets, the access door is opened and the baskets are taken out.


Oil Removal -Optional

An optional belt-type oil skimmer or re-circulating oil coalescer can be added to the wash tank for oil removal.


Re-circulating Air Drying

The SK4000-2T uses a fast and efficient drying system, resulting in faster cleaning cycles than competitive machines. The dryer incorporates Sharpertek's high volume and high velocity convection dryer which re-circulates the air rather than discharging it into plant atmosphere. This system re-circulates five times the air of competing systems, discharging the air flow through multiple slots aimed directly at into the tank. Over 95 percent of the air is re-circulated in the Sharpertek dryer, typically drying parts twice as fast while using lower air temperatures and half the energy of other systems.



Ergonomically-designed lid helps operators work efficiently and stress free. Operator places a parts basket into the washer, closes the lid, and presses a button. Parts are washed consistently according to the wash program. Operators are free to complete other work while the SK1000-2T cleans the parts. Removing the basket is just as simple. The basket merely lifts out. Easy loading and unloading speeds cleaning and reduces operator stress.
