When your chemical injection pump starts losing pressure or won’t prime properly, the upper housing might be the culprit. This part holds everything together on top of the diaphragm assembly, and if it’s cracked or warped from years of chemical exposure and temperature changes, your whole pumping system suffers. Getting the right replacement housing gets you back to consistent, reliable chemical delivery.
Key Features
- Precision-molded construction that maintains proper seal alignment with diaphragm components
- Chemical-resistant materials handle herbicides, fertilizers, and other agricultural chemicals without degrading
- Exact fit design ensures proper pump chamber volume for consistent flow rates
- Durable housing withstands the vibration and mounting stress of tractor and sprayer applications
Built for Real Farm Work
This upper housing is designed for Shurflo diaphragm pumps commonly used on farm sprayers, nurse tanks, and chemical injection systems. Whether you’re running a three-point sprayer for post-emergence herbicides, a pull-type applicator for liquid fertilizer, or a nurse tank setup for filling planters, this housing keeps your chemical delivery system working right when timing matters most.
Made to Last
Farm chemical pumps take a beating from corrosive materials, temperature swings, and constant vibration. This housing is built from materials that resist chemical attack and won’t crack under stress. The precision manufacturing ensures it maintains proper tolerances even after thousands of cycles, so your pump keeps delivering accurate chemical rates season after season.
Installation Notes
Remove the old housing carefully and inspect the diaphragm and valve seats while you have it apart. Clean all mating surfaces thoroughly before installing the new housing. Make sure all gaskets and seals are properly seated before tightening—overtightening can warp the housing and cause leaks. A light coating of compatible grease on the gasket helps ensure a good seal.
