The Multiquip 0201503A004 Impeller Nut is a genuine OEM component designed for the ST2010 submersible pump. As an authorized Multiquip replacement part, it is manufactured to the same specifications as the original, ensuring a correct, secure fit within the pump assembly. This nut is purpose-built to retain the impeller on the motor shaft, making it a critical part of sustained pump performance. If you are servicing or rebuilding an ST2010 submersible pump, using the correct OEM impeller nut is essential to restoring proper operation.
Key Features
- Genuine OEM Construction — Threaded to exact dimensional tolerances required for the ST2010 impeller shaft, ensuring consistent torque retention and secure seating.
- Direct-Fit Replacement — Installs in place of the original fastener without modification, threading directly onto the motor shaft as designed.
- ST2010 Compatibility — Confirmed fitment for the Multiquip ST2010 submersible pump; verify your model before ordering to ensure accuracy.
- Impeller Security — Keeps the impeller correctly positioned on the shaft so the pump moves water efficiently at rated flow and pressure. A loose or damaged nut causes impeller wobble, reduced output, and accelerated wear on the pump housing.
- Operational Safety — A properly torqued impeller nut prevents the impeller from backing off during operation, which can cause sudden loss of pumping capacity or internal damage to the pump casing.
The impeller nut is the fastener that secures the impeller — the rotating component that draws water in and forces it through the pump discharge — to the motor shaft. Without a properly tightened and undamaged impeller nut, the impeller cannot maintain its correct position on the shaft, leading to reduced water flow, vibration, and potential damage to surrounding pump components. When this nut loosens, corrodes, or strips, replacing it promptly with the correct OEM part restores the mechanical integrity of the pump and allows the ST2010 to return to full operating capacity.
