The Multiquip 0201503A005 Impeller Nut Washer is a genuine OEM component designed for the ST2010 submersible transfer pump. Sourced directly from Multiquip, this washer delivers the correct dimensions and material grade to maintain proper clamping force at the impeller nut, keeping the pump's rotating assembly secure during operation. Confirm your model against ST2010 fitment before ordering to ensure a direct, hassle-free installation.
Key Features
- Genuine OEM Material Grade — Manufactured to Multiquip's original specification, ensuring the washer delivers the correct load distribution and compression resistance needed at the impeller fastening point.
- Direct Drop-In Installation — Engineered to the exact bore diameter and thickness of the original, so it seats correctly against the impeller nut without shimming or rework.
- ST2010 Compatibility — Confirmed fitment for the Multiquip ST2010 submersible transfer pump series.
- Impeller Retention Integrity — A correctly fitted washer prevents the impeller nut from loosening under pump vibration, protecting shaft threads and maintaining consistent flow output.
- Essential Service Item — Replace this washer any time the impeller assembly is disassembled to restore full clamping integrity and avoid premature wear on mating components.
The impeller nut washer sits between the retaining nut and the impeller hub, distributing clamping load evenly across the fastener face to prevent the nut from loosening or biting into softer pump components. Without it, the impeller nut can work loose under the continuous vibration and hydraulic forces of pumping operation, leading to impeller slippage, reduced flow rate, and potential shaft thread damage. Replacing this washer during any impeller service is a low-cost step that protects the broader pump assembly and restores correct torque retention.
