Description
When your centrifugal pump starts making grinding noises or the impeller won’t stay locked to the shaft, there’s a good chance the woodruff key has sheared or worn out. This little semicircular piece of steel might look insignificant, but it’s what keeps your impeller properly aligned and connected to the drive shaft. Without it, your pump can’t move water, chemicals, or liquid fertilizer like it’s supposed to.
What You’re Getting
- Precision-cut steel key that locks the impeller securely to the pump shaft
- Proper fitment prevents slipping and ensures consistent pump performance
- OEM-quality construction that handles the torque and stress of pump operation
- Direct replacement part that fits right in the machined keyway
Built for Real Farm Work
This key fits Hypro 9000 and 9300 series centrifugal pumps that you’ll find on spray rigs, tank fill systems, and transfer operations around the farm. These pumps move everything from clean water to herbicide solutions, and when they’re not working right, your whole operation comes to a stop. Whether you’re filling spray tanks, transferring liquid fertilizer, or pumping irrigation water, this key makes sure power gets from the motor to the impeller.
Made to Last
Steel construction means this key won’t fail under the constant rotational stress that comes with pump operation. The precise dimensions ensure it fits snugly in both the shaft keyway and the impeller hub, eliminating the play that causes premature wear and pump damage.
Installation Notes
Installing a woodruff key requires removing the impeller, which means draining the pump first. The key sits halfway in the shaft and halfway in the impeller hub – make sure both keyways are clean before installation. A small dab of grease helps hold the key in place while you slide the impeller back on. Always check that the key is properly seated before tightening everything back up.
