0558004062 - ESAB Replacement Rotary Vane Coolant Pump 115PSI 100GPH

High-Performance Replacement Coolant Pump for Welding Systems

The ESAB 0558004062 is a precision-engineered coolant pump designed to restore and maintain the critical fluid circulation within industrial welding water coolers. As a vital component in water-cooled MIG and TIG welding setups, this pump ensures that coolant is delivered at the necessary pressure and flow rate to effectively dissipate heat generated during high-amperage welding operations. Failure of a coolant pump can lead to catastrophic torch failure, downtime, and costly repairs, making this genuine ESAB replacement part an essential inventory item for maintenance and repair operations.

Technically, this unit is a rotary vane pump, a type favored in the industry for its positive displacement characteristics and ability to maintain steady pressure. It is factory-calibrated to deliver a discharge pressure of 115 PSI, which is the optimal range for overcoming the flow resistance found in long torch cable assemblies and small internal cooling passages of modern welding torches. With a flow capacity of 100 Gallons Per Hour (GPH), it provides ample volume to ensure that the coolant temperature remains stable, even during extended duty cycles.

Constructed with a durable brass body and high-quality internal components, the pump is built to withstand the rigors of industrial environments. It is compatible with standard welding coolants, including ethylene glycol mixtures and proprietary coolants recommended by ESAB. The pump is designed for direct integration into specific ESAB cooling units, ensuring a seamless fit and reliable performance. Regular inspection and replacement of the coolant pump are recommended to maintain the longevity of the entire welding system.
