Description
When your Fimco sprayer pump starts losing prime or won’t hold pressure like it should, the check valves are usually the culprit. These little valves keep the spray solution flowing in the right direction, but after a season or two of mixing chemicals and dealing with debris, they can get sticky or worn out. This repair kit gets your pump back to working like new.
What You’re Getting
- Complete check valve assembly that stops backflow and maintains proper pump pressure
- Quality seals and components designed to handle common agricultural chemicals
- Direct replacement parts that fit like the originals—no modifications needed
- Everything you need to restore proper pump operation and consistent spray pressure
Built for Real Farm Work
This kit works with Fimco pumps including models 5275087 and 5275088, the popular 12-volt diaphragm pumps found on many ATV and small tractor sprayers. Whether you’re spot-spraying weeds, applying herbicide to food plots, or handling general farm spraying duties, these pumps see a lot of action and need reliable check valves to keep working properly.
Made to Last
Agricultural spraying puts check valves through the wringer with chemical exposure, temperature changes, and constant pressure cycling. This kit uses materials that can handle the harsh environment inside a sprayer pump, keeping the seals flexible and the valve action smooth season after season.
Good to Know
Replacing check valves isn’t too tough if you’re handy with basic tools, but take your time and keep track of how everything comes apart. Clean out any debris from the pump housing while you’re in there, and consider replacing both inlet and outlet valves at the same time—if one’s gone bad, the other isn’t usually far behind.
