177246 - Miller Coolmate 3 and 4 Replacement Coolant Pump Assembly

Restore Optimal Cooling Performance

In the high-stakes world of industrial fabrication, equipment downtime is the enemy of profitability. The Miller 177246 Coolant Pump is the critical component required to maintain the operational integrity of your Miller Coolmate 3 and Coolmate 4 water coolant systems. Designed as a direct OEM replacement, this pump restores the vital circulation needed to manage thermal loads in high-amperage TIG and MIG applications. When your cooling system fails, production halts; installing genuine Miller parts ensures that your repair is robust, reliable, and ready for continuous duty cycles.

The 177246 pump utilizes a proven rotary vane mechanism, a standard in the industry for delivering consistent pressure and flow without pulsation. This consistency is paramount for protecting water-cooled power cables and torch heads from catastrophic failure due to overheating. Miller has engineered this component to withstand the specific chemical properties of approved coolants, resisting corrosion and wear that typically plague inferior aftermarket alternatives. By maintaining the correct flow rate, this pump ensures that heat is efficiently transferred away from the arc zone to the radiator, allowing your welding power sources to operate at their rated duty cycles without thermal interruption.

Maintenance managers and shop foremen understand that preventative maintenance and timely repairs are cheaper than replacing burnt-out torches. This pump assembly is designed for straightforward installation into existing Coolmate housings, minimizing the labor time required for the swap. Whether you are refurbishing an older Coolmate 3 unit or servicing a fleet of Coolmate 4 systems, the Miller 177246 provides the assurance of factory-spec performance. It is built to meet the rigorous demands of heavy fabrication shops, aerospace manufacturing, and precision pipe welding environments where equipment reliability is non-negotiable.

Investing in the correct replacement pump protects your broader investment in Miller welding technology. A functioning coolant system is the lifeline of your water-cooled torch; without it, consumables degrade rapidly, and weld quality suffers. Trust in the engineering validation of Miller Electric and choose the 177246 Coolant Pump to keep your shop running at peak efficiency.
