Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact 6.32 x 25.4 specifications, ensuring the key seats flush and transfers torque cleanly without rocking or slipping.
- Direct Drop-In Fit — Machined to slot directly into the keyway on compatible trash pump shafts, requiring no filing, shimming, or modification to install correctly.
- Broad Trash Pump Compatibility — Confirmed fitment across QP3TY, QP3TH, QP-40TE, QP40TH, and QP3TE Multiquip trash pump models.
- Locks Impeller to Shaft — A correctly sized key prevents impeller slippage under load, maintaining full pump flow and discharge pressure during demanding dewatering or site cleanup operations.
- Protects Shaft and Hub — Using the correct OEM key prevents keyway wallowing — damage that can quickly escalate into costly shaft or impeller hub replacement.
A shaft key is a small but critical drive component that interlocks the rotating shaft with the impeller hub, ensuring both turn as a single unit. Without it — or with an incorrectly sized key — the impeller can slip on the shaft, causing a sudden and complete loss of pumping performance. A worn or sheared key also accelerates damage to the keyway groove itself, turning a simple hardware replacement into a much larger repair job.
