The Multiquip 100KDO7521 Impeller ST-4125 is a genuine OEM impeller designed for the ST-4125 submersible pump. As a factory-sourced component, it is manufactured to the exact tolerances required to maintain proper hydraulic performance and flow characteristics within the pump. Sourced directly through Multiquip's authorized parts network, the part ensures correct fitment for ST-4125 series equipment without guesswork or modification.
Key Features
- OEM-Grade Hydraulic Tolerancing — Manufactured to precise clearance specs that govern flow efficiency and pressure output in the ST-4125 pump.
- Direct-Fit Replacement — Engineered to match the original impeller shaft bore, vane profile, and housing interface for a straightforward swap.
- Confirmed ST-4125 Fitment — Verified compatible with the Multiquip ST-4125 submersible pump series.
- Sustained Flow Performance — A correctly sized impeller maintains rated GPM output; a worn or damaged impeller causes cavitation, pressure loss, and accelerated pump wear.
- Genuine Multiquip OEM Part — Supplied through authorized distribution channels, so you receive the same component installed at the factory.
The impeller is the rotating core of a submersible pump's wet end — its spinning vanes draw water in and accelerate it outward, generating the flow and pressure the pump is rated to deliver. When an impeller wears down, becomes clogged, or sustains damage, the pump loses capacity, draws more current, and can overheat. Replacing the impeller with the correct OEM part restores the pump to its original performance specification and protects the motor from the strain of operating against degraded hydraulics.
