Multiquip 30150 3" Dia. Impeller

The Multiquip 30150 3" Dia. Impeller is a genuine OEM component designed for HTX44K5 and HTX44K4 hydrostatic ride-on trowels as well as ST1 and ST1F submersible pumps. As a direct OEM replacement, this impeller is manufactured to the same specifications as the original part, ensuring proper fit and function across compatible Multiquip equipment. Sourced through DHS Equipment, part number 30150 is the correct choice when restoring pump performance or completing a scheduled service on any of these machines.

Key Features

• OEM-Matched Hydraulic Geometry — Blade profile and diameter are held to the same tolerances as the original, maintaining designed flow rate and pressure output.
• Drop-In Replacement — Mounts directly to the existing shaft and housing on compatible units without machining or adaptation.
• Broad Fitment Coverage — Confirmed for HTX44K5, HTX44K4 ride-on trowels and ST1 / ST1F submersible pumps under a single part number.
• Sustained Pump Efficiency — A worn impeller reduces flow volume and increases motor load; replacing with a correctly dimensioned OEM part restores designed pumping capacity.
• Genuine Multiquip Part — Backed by Multiquip's OEM supply chain, so you receive the exact component specified for these machines — not a generic approximation.

An impeller is the rotating core of a centrifugal or submersible pump, using curved vanes to accelerate fluid outward and generate flow. In submersible applications such as the ST1 and ST1F, the impeller draws water in through the inlet and pushes it up through the discharge — any wear, erosion, or cracking of the vanes directly reduces pumping volume and can overload the motor. In the hydraulic circuits of HTX44K5 and HTX44K4 ride-on trowels, a correctly functioning impeller maintains the fluid pressure needed for smooth blade pitch control and drive response. Replacing a degraded impeller promptly prevents cascading wear on seals, housings, and drive components downstream.
