The Multiquip 02015 Impeller Nut is a genuine OEM component designed for RAMMAX walk-behind rollers and ST-series submersible pumps across multiple configurations. As an authorized Multiquip OEM part, the 02015 is built to the same standards as the original hardware installed at the factory, ensuring a correct, secure fit without the guesswork of cross-referencing aftermarket alternatives. Verified fitment includes the RW1810, RW3010, ST2010, ST2037, ST2037F, ST2038P, ST2040T, ST2040TF, ST2047, ST2047B, ST3020B1, and ST3020BCUL. Sourcing the correct impeller nut matters — an improperly secured impeller is a leading cause of pump inefficiency and premature component wear, making this a critical service part for any scheduled maintenance or repair.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Multiquip's original torque and material specifications, so the nut secures the impeller with the clamping force the design requires — not an approximation of it.
- Direct-Fit Replacement — Thread pitch and bearing surface dimensions match the original fastener exactly, threading directly onto the impeller shaft without reworking or chasing threads.
- Broad Verified Fitment — Covers RW1810 and RW3010 RAMMAX rollers as well as the full ST2010 through ST3020 submersible pump lineup, including float-switch and puddle-sucker variants.
- Protects Impeller Integrity — A correctly torqued impeller nut prevents impeller wobble, shaft scoring, and loss of hydraulic efficiency — failures that escalate quickly in high-cycle pump and roller applications.
- Critical for Pump Safety and Performance — A loose or failed impeller nut in a submersible pump can result in uncontrolled impeller movement, seal breach, and potential motor flooding — making correct fastener replacement essential during any impeller service.
The impeller nut is the primary fastener that locks the impeller onto the rotor shaft inside a pump or roller drive assembly. In submersible pump applications, it holds the impeller in precise axial position so that the vanes maintain correct clearance within the pump casing — any loosening reduces flow rate, increases cavitation risk, and accelerates wear on both the impeller and the volute. When the nut is worn, cross-threaded, or missing, the impeller can shift under load, leading to vibration, seal failure, and ultimately motor damage. Replacing it with the correct OEM part, such as the Multiquip 02015, restores the designed clamping load and keeps the assembly running as intended.
