Product Description
The IPM GP-20D 3:1 Air Powered Drum Pump is designed for transferring and supplying higher-viscosity fluids from standard 55-gallon drums. Built with a 3:1 pressure ratio, this pump is well suited for spray foam, polyurea, polyurethane, coatings, adhesives, resins, solvents, lubricants, and other chemical transfer applications.
The GP-20D features a single-piston air-powered design with an easily detachable air motor for faster service and changeover. Its robust pump packings and specially designed piston seals help reduce chemical buildup on the shaft, which is especially important when handling isocyanates that can crystallize after exposure to air.
This pump is commonly used by spray foam and polyurea contractors for chemical supply, spray gun supply, dispensing valve supply, and general fluid transfer.
