The Multiquip 0520030413 Key 4.7 x16 mm is a genuine OEM component designed for QP2TZ and QP2TH series trash pumps. This small but critical drive key ensures the impeller or pump shaft component is positively locked in position, maintaining proper rotational alignment during operation. As a direct OEM replacement, the part is manufactured to the same specification as the original, so installation is straightforward with no guesswork on fit or sizing.
Key Features
- Genuine OEM Construction — Manufactured to exact dimensional tolerances for the 4.7 x16 mm keyway profile, ensuring the correct interference fit between shaft and mating component.
- Direct Shaft-to-Component Alignment — Slots directly into the existing keyway on QP2TZ and QP2TH pumps with no machining or modification to the shaft or hub.
- Confirmed Fitment — Verified OEM replacement for QP2TZ and QP2TH Multiquip quick-prime trash pumps.
- Maintains Full Pump Output — A properly seated drive key keeps the impeller locked to the shaft at full rotational speed, preserving the pump's rated flow and lift performance.
- Prevents Shaft and Hub Damage — A worn or missing key allows slippage between mating surfaces, which rapidly damages both the shaft and the driven component; replacing it promptly protects the surrounding assembly.
A drive key is a small precision-machined piece that fits into matching slots — called keyways — cut into both a rotating shaft and the component mounted on it, such as an impeller or pulley hub. By bridging these two keyways, the key locks the shaft and the mounted component together so they rotate as a single unit, transferring power without slippage. When a key shears or wears, the driven component spins independently of the shaft, causing an immediate loss of pump output and accelerating damage to the surrounding hardware.
