GRACO D54381 Husky 716 3/4 Inch Stainless Diaphragm Pump

The D54381 Husky 716 SS is a 3/4 inch air operated double diaphragm pump designed for reliable transfer of industrial fluids requiring corrosion resistance and stable flow performance.

Featuring a stainless steel fluid section, PTFE/EPDM diaphragm and FKM ball configuration, this pump provides excellent durability for demanding fluid handling environments.

The pneumatic diaphragm design eliminates mechanical seals and electric drive components, reducing leakage risks and allowing flexible installation in industrial systems.

Compared with smaller Husky 307 and Husky 515 models, the Husky 716 provides higher flow capacity and a more robust stainless steel construction for heavier industrial applications.
