The Multiquip 1625173034 is a genuine OEM Water Pump Assembly V1305-E2B designed for DLW400ES series diesel light welders. As a factory-authorized component, this assembly is sourced directly through Multiquip to ensure correct specification and direct interchangeability with the original part. Confirmed fitment covers the DLW400ES, DLW400ESA, and DLW400ESA1 models. Sourcing the correct OEM assembly from DHS Equipment means you get the right part the first time, keeping your welder running at full capacity.
Key Features
- Genuine OEM Cooling Circuit Integrity — Factory-sourced assembly maintains the correct flow rate and seal geometry for the V1305-E2B engine cooling system, avoiding the compromises that come with ill-fitting substitutes.
- Direct-Swap Installation — Matches the original bolt pattern, inlet/outlet orientation, and shaft configuration of the DLW400ES series, so the assembly installs against the existing mounts without reworking fittings or brackets.
- Confirmed Fitment for DLW400ES Series — Verified for DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder models.
- Sustained Engine Temperature Control — A fully functional water pump keeps coolant circulating at the correct rate through the V1305-E2B engine; a worn or failed pump leads to overheating, power loss, and potential engine damage during extended welding operations.
- Cooling System Safety Assurance — Coolant system integrity is critical on engine-driven welders operating under continuous load; using the correct OEM pump assembly reduces the risk of thermal events caused by inadequate coolant flow.
The water pump assembly circulates engine coolant through the V1305-E2B engine's cooling circuit, drawing heat away from the engine block and cylinder head and routing it through the radiator for dissipation. Without adequate coolant flow, engine temperature rises rapidly under load, triggering overheat shutdowns or causing permanent damage to internal engine components. When the pump impeller wears, the shaft seal leaks, or the housing cracks, coolant flow drops off and the engine's thermal management is compromised — making timely replacement of the 1625173034 assembly essential to keeping the DLW400ES welder operational.
