Multiquip 1988373510 Water Pump Impeller

The Multiquip 1988373510 Water Pump Impeller is a genuine OEM component designed for DAC7000SS, DAC7000SSW, and DAC7000SSA ultra-silent diesel generators, as well as DLW300ES series diesel light welders. As a direct OEM replacement, this impeller is manufactured to the same specification as the original, ensuring correct dimensional fit within the water pump housing without additional modification. Sourced directly through Multiquip's authorized parts network, the 1988373510 is the correct factory-specified part for maintaining proper engine cooling across these generator and welder platforms.

Key Features

• Genuine OEM Construction — Manufactured to the original blade geometry and material tolerances required for consistent coolant flow in diesel-powered equipment water pump systems.
• Direct Housing Fit — Engineered to seat correctly within the original water pump assembly on compatible Multiquip units, maintaining proper clearances between impeller and housing.
• Broad Series Compatibility — Fits DAC7000SS, DAC7000SSW, and DAC7000SSA ultra-silent diesel generators along with DLW300ES series diesel light welders.
• Sustained Cooling Performance — A properly functioning impeller maintains adequate coolant circulation to protect the engine from overheating during extended operation; a worn or damaged impeller can lead to coolant flow loss and engine damage.
• Thermal Safety Assurance — Correct impeller function is critical to preventing engine overtemperature conditions in enclosed generator and welder applications where heat management is essential to safe continuous operation.

The water pump impeller is the rotating component inside the engine's coolant pump responsible for drawing coolant through the system and circulating it across the engine block, cylinder head, and radiator to dissipate heat. Without adequate impeller function, coolant flow drops, engine temperatures rise, and sustained overheating can cause serious internal engine damage. When an impeller becomes cracked, eroded, or loses blade integrity through normal wear, replacing it promptly with the correct OEM part restores full cooling capacity and protects the engine investment.
