Description
When your sprayer pump starts making grinding noises or loses its prime pressure, there’s a good chance the internal drive ring gear has worn out. This small but critical part transfers power from the pump’s input shaft to the rollers that move your spray solution, and when it fails, you’re looking at downtime right when you need to be in the field.
What You’re Getting
- Precision-machined gear teeth that mesh perfectly with your pump’s rotor assembly
- Durable construction designed to handle the constant rotation and chemical exposure
- Direct replacement part that restores proper pump operation and pressure
- Quality materials that stand up to the demands of agricultural spraying
Built for Real Farm Work
This ring gear fits inside Hypro roller pumps that are the workhorses of agricultural and industrial spraying operations. Whether you’re running a pull-behind sprayer, a self-propelled unit, or a smaller spot-spraying rig, this gear keeps the pump’s internal components synchronized and working smoothly.
Made to Last
Farm spraying puts serious stress on pump components—chemicals, pressure cycles, and long operating hours all take their toll. This ring gear is built with the same specifications as the original equipment, so it’ll handle whatever your operation throws at it season after season.
Good to Know
Replacing the ring gear requires disassembling the pump, so it’s a good time to inspect other wear items like seals and rollers. If you’re hearing noise from your pump or noticing pressure drops, don’t wait—a failed ring gear can damage other expensive internal components.
