Description
When your Banjo pump starts leaking or losing prime, that little o-ring in the pump body is often the culprit. It might look like just a simple rubber ring, but this seal keeps the pump working properly by preventing air leaks and maintaining the pressure you need for reliable fluid transfer. Whether you’re pumping water for livestock or transferring chemicals for crop spraying, a good seal makes all the difference.
What You’re Getting
- Precision-molded seal that fits snugly in your Banjo pump body
- Durable rubber compound that resists chemicals and temperature extremes
- Prevents air infiltration that causes pump cavitation and poor performance
- Direct replacement part that restores your pump’s original sealing capability
Built for Real Farm Work
This o-ring works with Banjo’s popular 2-inch poly transfer pumps, the workhorses you’ll find on farms and ranches everywhere. These pumps handle everything from filling water tanks to moving liquid fertilizer, and they need reliable seals to keep doing their job day after day in tough agricultural conditions.
Made to Last
Made from quality rubber compounds, this o-ring stands up to the chemicals, UV exposure, and temperature swings that come with farm use. It’s designed to maintain its flexibility and sealing properties even when exposed to fertilizers, herbicides, and other agricultural fluids that would destroy cheaper seals.
Good to Know
Installing a new o-ring is straightforward—just make sure the sealing surfaces are clean and free of debris before installation. A light coating of compatible lubricant helps with assembly and prevents damage to the seal. Keep a spare on hand since o-rings are wear items that eventually need replacement.
