The Wacker Neuson is a genuine OEM Key 5.5 X 6.5 X 8 designed for the PSW3 1500 and PS2-1500 series submersible pumps. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring correct engagement between the shaft and driven component. This key fits multiple PSW3 1500 configurations, including the 220V/60Hz 2hp unit, as well as the PS2-1500 model. Ordering by verified part number means you get the exact piece your pump was built around — no guesswork required.
Key Features
- Precision-Dimensioned Shaft Key: — Cut to an exact 5.5 x 6.5 x 8 profile, this key seats fully in the keyway to transfer torque without slippage or play.
- Genuine OEM Part: — Sourced directly through Wacker Neuson's authorized parts program, so the material grade and dimensional tolerances match the original production component exactly.
- Drop-In Replacement: — Engineered to seat directly into the existing keyway slot on compatible PSW3 1500 and PS2-1500 pump shafts without alteration.
- Broad PSW3 1500 Coverage: — Confirmed fit across PSW3 1500 variants, including the 220V/60Hz 2hp 49-foot cord model, as well as the PS2-1500 submersible pump.
- Protects Shaft and Impeller Alignment: — A correctly fitted key locks the impeller or coupling to the shaft, preventing rotational lag that can accelerate wear on both components and compromise pump output.
A shaft key is a small rectangular or square drive component that sits in a machined slot — called a keyway — cut into both the shaft and the mating hub or impeller. Its job is to lock the two parts together rotationally so that torque from the motor transfers cleanly to the pump impeller without slipping. When a key shears, deforms, or works loose, the shaft spins independently of the impeller, causing an immediate loss of pumping capacity and accelerating damage to the shaft bore and hub. Replacing a worn or failed key promptly with the correct-dimension piece restores full torque transfer and protects the surrounding components from secondary wear.
