Multiquip 1988 Water Pump Impeller

The Multiquip 1988 Water Pump Impeller is a genuine OEM replacement designed for a broad range of Multiquip equipment including the DLW300ES, DAC7000SS, DAC7000SSA, DAC7000SSW, QPT305SLT, QPT205SLT, QP305SLT, QP205SLT, JWN24HTCSL, HHN34TVD, HHN31V, HTN28K, HTN27K, and HTN-series ride-on trowels. As a factory-sourced component, part 1988 meets the same dimensional and material standards as the original part it replaces. This impeller is a direct fit for the water pump assemblies found across Multiquip welders, ultra-silent diesel generators, centrifugal pumps, and Whiteman ride-on trowels — making it a versatile OEM service part for mixed fleets. Sourced through DHS Equipment, you receive an authentic Multiquip component backed by the manufacturer.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original impeller geometry and material grade, ensuring correct flow rate and pressure output for the water pump assembly.
• Direct-Fit Replacement — Engineered to drop into the existing water pump housing without machining or modification to mounting surfaces or shaft interface.
• Wide Fitment Coverage — Confirmed fit across DLW300ES welders, DAC7000SS ultra-silent generators, QPT305SLT and QP205SLT centrifugal pumps, and HTN/HHN/JWN ride-on trowel series.
• Sustained Coolant Flow — A correctly seated impeller maintains the circulation needed to keep engines and pump systems within operating temperature range; a worn or cracked impeller reduces flow and accelerates thermal stress.
• Corrosion-Resistant Material — Constructed from materials suited to continuous water contact, resisting degradation from coolant additives and pump fluid over extended service intervals.

The water pump impeller is the rotating component inside the pump housing responsible for moving coolant or water through the system. Its spinning vanes generate the flow that carries heat away from the engine or maintains pressure in pump-driven applications. When an impeller wears, cracks, or loses a vane, coolant circulation drops — leading to overheating, cavitation, or loss of pump output. Replacing a damaged impeller with a correctly sized OEM part like the Multiquip 1988 restores full flow capacity and protects the engine and pump system from heat-related damage.
