WHY SELF PRIMING DIAPHRAGM PUMPS MATTER
When fluids get thick and solids show up, these gear-driven workhorses keep moving the mix—without air supply and without babying—where other pumps stall.
Product Overview
Self Priming Diaphragm Pumps
These “TuffStuff” diaphragm pumps are “workhorses” often known as “mud or sludge pumps specifically designed and built to pump mud, slurry, oil, grease and other thick liquids that are flow-able.
While we use mostly the electric drive where our air operated SkimHawg AOD pumps can’t work due to lack of air, these TuffStuff pumps are available powered the way you need it. Diesel or gas engine driven YEP!
Built-in check valve assures self-priming to 20 feet after initial prime. Heavy duty forged gear driven transmission is designed to operate pump at 40 strokes per minute for electric motor models and 60 strokes per minute for engine driven models. Each unit includes a 2” or 3” NPT steel suction strainer, two NPT nipples and a wheel kit for portability.
Available in 2” size that can pass solids up to1 -1/4” in diameter or the big 3” model that can pass 1 5/8” solids. Solids are almost always present on oil skimmer jobs. The TuffStuff pumps make it easy to work where compressed air is not available. With Honda, Briggs and Hatz Diesel drive, these pumps come with a wheel kit to get you moving to the job. Goes and operates where no other pumps can go.
TuffStufft fits thru doorways, up stairways and can be used from rooftops to basements to swamps to shipyards or oil spill sites. Get it going with TuffStuff!
