The Multiquip 1625973032 Water Pump Assembly is a genuine OEM component designed for BLW-400SSW, KD1800, KD1800KD6, and KD6 series equipment. As a direct factory replacement, this assembly restores proper coolant circulation to your machine with no guesswork on fitment. DHS Equipment supplies this part as an authorized Multiquip source, so you can be confident you are receiving the correct, unmodified OEM unit. Verify your model code against the confirmed fitment list before ordering to ensure a direct match.
Key Features
- Genuine OEM Construction — manufactured to Multiquip's original design specifications, ensuring correct flow rate, impeller geometry, and housing dimensions for this application.
- Direct-Fit Replacement — engineered to mount to the existing coolant circuit using the original bolt pattern and port sizing, streamlining the swap on BLW-400SSW and KD-series machines.
- Confirmed Fitment — compatible with BLW-400SSW, KD1800, KD1800KD6, and KD6 equipment; cross-reference your model code before ordering.
- Sustained Thermal Management — a properly functioning water pump keeps coolant moving at the correct rate, protecting the engine or power unit from heat-related wear and maintaining consistent output under load.
- Coolant System Integrity — a failing pump can allow coolant to leak internally or externally, creating both overheating risk and potential fluid contamination; replacing with a genuine assembly restores the sealed system as originally designed.
The water pump assembly circulates coolant through the engine or power unit to carry heat away from critical components and maintain safe operating temperatures. When the pump wears out or fails, coolant flow drops or stops entirely, causing the machine to overheat and risk serious internal damage. Replacing the 1625973032 assembly with a genuine OEM unit brings coolant delivery back to the original design specification, keeping your BLW-400SSW or KD-series equipment running at its full rated capacity.
