The Miller 5515 Coolant Pump<\/strong> is a critical component designed to maintain the efficiency and longevity of your water-cooled TIG welding setup. Engineered specifically for Miller Coolmate systems, this rotary vane pump delivers a steady flow rate of 100 Gallons Per Hour (GPH)<\/strong>, ensuring that your TIG torch remains at optimal operating temperatures even during high-amperage applications. Overheating is a primary cause of torch failure and consumable degradation; replacing a worn-out pump with this genuine Miller part restores your system’s ability to dissipate heat effectively.<\/p>\n This pump features a Clockwise (CW) rotation<\/strong> configuration, making it the exact match for specific motors found in the Coolmate 3 and Coolmate 4 units. Constructed with a durable brass body, the Miller 5515 is built to withstand the rigors of industrial environments and continuous duty cycles. It includes an integrated strainer mechanism that helps filter out particulates from the coolant, protecting the internal vanes and the torch lines from clogging. Whether you are performing precision aerospace welding or heavy fabrication, maintaining consistent coolant flow is non-negotiable for weld quality.<\/p>\n Installation of the Miller 5515 is straightforward for maintenance personnel familiar with water cooler repair. The pump mounts directly to the motor via a standard clamp or flange connection. By choosing this genuine OEM replacement, you ensure proper fitment and pressure specifications, avoiding the risks associated with generic pumps that may not match the pressure relief settings required by Miller torches. Keep your welding operations running smoothly and protect your equipment investment with this high-quality replacement pump.<\/p>\nKey Features<\/h3>\n
