Graco Husky 307 Diaphragm Pump
The Graco Husky 307 is an air-operated double diaphragm pump that offers a maximum fluid flow of 26 litres per minute, for the fast, effective transfer of fluids.
It is one of the smaller pumps in the Graco Husky range, known for their exceptionally rugged design and long lifespan.
The Husky 307 features a stall-free, low-pulsation air valve, for smooth, rapid changeovers. It is fully groundable and is simple to maintain, with fast, straightforward assembly/disassembly and easy to service air valve and ball checks.
