OVERVIEW

Reliable Cooling for High-Performance TIG Welding

The Miller 5515 Coolant Pump 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), 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.

This pump features a Clockwise (CW) rotation 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.

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.

FAQ

The Miller 5515 pump is rated for approximately 100 Gallons Per Hour (GPH), which is the standard flow requirement for most Miller Coolmate systems.

This pump is specified as Clockwise (CW) rotation. You can usually verify this by looking at the arrow on the pump body or checking your existing pump's part number.

Yes, the Miller 5515 is the standard replacement pump for the Miller Coolmate 3 and Coolmate 4 systems that require a clockwise rotation pump.

Typically, the pump is sold as the bare pump unit. You may need to reuse your existing drive coupling or purchase one separately if it is worn.

Yes, like most rotary vane pumps of this style, there is usually a pressure adjustment screw that allows you to fine-tune the output pressure, though it comes factory preset.

Common signs include a low flow alarm on your welder, the torch handle becoming uncomfortably hot, or the pump making loud grinding or rattling noises.

While it is designed for Miller systems, it is a standard rotary vane pump form factor. If the mounting flange, shaft drive, and rotation match, it can be used in other systems, but verify specs carefully.

Yes, this is a genuine Miller/Weldcraft replacement part, ensuring it meets the original specifications for your equipment.
