Power Paint Gun Cleaning with Durable, Reliable Pumps
Herkules industry-leading paint gun washers are powered by durable pumps that run for thousands of cleaning cycles. Most current paint gun washers are powered by the 338 Pump, but we are proud to have a number of older styles and models still in service, powering paint gun washers across the country.
Although our pumps are powerful, their lifespan is not as long as those of our classic blue tubs. For that reason, we have several kits that will enable customers to retro-fit a new 338 pump into their paint gun washer. Pictured below are the pumps currently in use, with both current and classic units no longer manufactured by Herkules. Update and/or repair information for each pump accompanies the picture. For additional assistance, either visit our Frequent Asked Questions page, or contact us weekdays from 8:30 a.m. until 5 p.m. Eastern Standard Time.
To purchase any of the pumps or pump kits currently available, select “Add to Cart” in the respective section.
