Multiquip 3015010502 3" Dia. Impeller

The Multiquip 3015010502 3" Dia. Impeller is a genuine OEM component designed for ST1 and ST1F submersible pump models. Sourced directly from Multiquip, this impeller is manufactured to the exact specifications of the original part, ensuring a correct, direct-fit installation in compatible units. Verified fitment covers the ST1 and ST1F submersible pump series. Keep this part on hand as a planned maintenance item or a fast-response replacement when your pump's flow performance begins to drop.

Key Features

• OEM-Matched Flow Geometry — Cast and profiled to the original hydraulic design, maintaining the intended flow rate and pump efficiency for ST1 and ST1F models.
• Direct-Fit Installation — Matches the original shaft bore, vane count, and housing clearances so it drops into place without modification during a standard pump rebuild.
• Confirmed Fitment for ST1 and ST1F — Part number 3015010502 is verified against Multiquip ST1 and ST1F submersible pump assemblies for accurate ordering.
• Sustained Pumping Output — A correctly sized impeller maintains rated flow volume and lift head; a worn or damaged impeller causes cavitation, reduced output, and accelerated seal wear throughout the pump.
• Genuine Multiquip OEM Part — Produced under Multiquip's OEM standards, giving you confidence that material grade and dimensional tolerances match the original pump design.

The impeller is the rotating core of a centrifugal pump — it converts engine or motor power into fluid velocity by spinning water outward through its vanes and into the pump volute. In a submersible pump like the ST1 and ST1F, the impeller must maintain tight clearances within the housing to sustain lift head and flow rate; even moderate erosion or chipping of the vanes will reduce pumping capacity noticeably. A worn impeller also places additional load on the motor bearings and mechanical seal, so replacing it promptly when performance drops helps protect the broader pump assembly.
