Built for Real Farm Work
This pump head works with specific Fimco pump models including the 5281372 and 5151088 units commonly found on field sprayers, ATV sprayers, and spot spraying rigs. Whether you’re applying herbicides to crop fields, spraying fence rows, or treating pastures, this head handles the chemical exposure and vibration that comes with the territory.
Made to Last
Fimco builds their pump components to withstand agricultural chemicals, temperature swings, and the constant start-stop operation of field spraying. The internal seals and diaphragm are designed to maintain their flexibility and sealing properties even after thousands of cycles.
Good to Know
Before you start the replacement, make sure to drain the pump and depressurize the system. The head assembly typically bolts on with standard fasteners, but check your pump’s specific mounting style. It’s a good time to inspect and clean the pump’s mounting surface to ensure a proper seal.
