The Multiquip 0202020006 Impeller Key ST-2020, 2020-1 is a genuine OEM replacement part designed for the ST-2020 submersible pump. Sourced directly through Multiquip's authorized parts network, this key ensures the impeller is correctly locked to the pump shaft for dependable operation. It is a direct-fit replacement for ST-2020 and ST-2020-1 series units, with no modification needed to the existing shaft or impeller assembly. Keeping this small but critical component in good condition is essential to maintaining full pump output and protecting the rest of the drive system.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original specifications, ensuring correct material hardness and dimensional accuracy for a secure shaft-to-impeller lock.
- Direct-Fit Replacement — Engineered to drop into the existing keyway slot on ST-2020 and ST-2020-1 submersible pump models without reworking the shaft or impeller hub.
- ST-2020 Series Fitment — Confirmed compatible with ST-2020 and ST-2020-1 submersible pump units; verify your model before ordering.
- Prevents Impeller Slippage — A properly seated impeller key transfers rotational force cleanly from the shaft to the impeller, maintaining rated flow and discharge pressure. A worn or missing key causes the impeller to slip, drastically reducing pump output.
- Critical Drive-System Protection — Impeller slippage from a failed key can cause uneven loading on the shaft and bearing, accelerating wear on surrounding components and leading to more extensive pump damage.
The impeller key is a small precision component that sits in a machined slot — the keyway — between the pump shaft and the impeller hub, locking the two together so they rotate as a single unit. Without it, the shaft spins freely inside the impeller, and the pump loses all ability to move water effectively. When an impeller key shears, wears down, or goes missing, the result is immediately noticeable: the motor runs but water output drops sharply or stops entirely. Replacing a worn key promptly protects the shaft, impeller, and bearing from the secondary damage that impeller slippage causes.
