Among the Original Stokes Remanufactures
1985
2025
Stokes approached our founder in 1985 to start rebuilding their pumps in the midwest region. Over the last 40+ years, we’ve refined that process, built a dedicated machine shop, applied that expertise to remanufacturing other brands of vacuum pumps, and became the only Stokes remanufacturer trusted by the biggest names in the industry. We demand more from our remanufactured pumps. Shouldn’t you?
Built on a Higher Standard
Bolt-In Replacement
With a size and shape like your existing Stokes 412 pump, our vacuum pumps can be easily bolted into your space.
On-Board Filtration
Our pumps automatically flush out particulates and free acid radicals for reduced wear rates and more runtime between rebuilds.
Failsafe Lubrication
In the event of the attached oil pump’s failure, atmospheric pressure pushes oil into the vacuum pump.
U.S. Manufactured Parts
Our castings are manufactured here in America, and that commitment to American-made parts ensures long-lasting quality.
Sentinel System Add-On
Sensors, gauges, and an onboard PLC alert you of maintenance needs to extend pump life. For HD300, HS430, Stokes 412H11, 412J14.
Drilled Hinge Bars
Delivers oil directly to the wear zone between hinge bar and piston slides—flushing out debris where buildup typically occurs to avoid vacuum loss pressure.
