0349310718 - ESAB MTP 600 Pump Seal and Repair Kit

Technical Overview of the ESAB MTP 600 Pump Repair Set

The ESAB 0349310718 Pump Repair Set is a specialized maintenance kit engineered for the refurbishment of MTP 600 series coolant pumps. These pumps are integral components in various ESAB water cooling units, such as the OCE series, which are tasked with circulating coolant through high-amperage TIG and MIG torches. Over time, the mechanical seals and internal gaskets of the pump can degrade due to thermal cycling, fluid contaminants, or general wear, leading to pressure drops and fluid leaks.

This genuine OEM kit provides the exact replacement components necessary to overhaul the pump head. It typically includes the primary mechanical seal, housing gaskets, and O-rings required to re-seal the pump chamber effectively. By using genuine ESAB parts, technicians ensure that the dimensional tolerances and material compatibility match the original factory specifications. This is critical for maintaining the hydraulic efficiency of the cooling loop, ensuring that the pump can deliver the required flow rate (l/min) and pressure (bar) to effectively remove heat from the welding torch.

Installation of this repair set is a cost-effective alternative to replacing the entire pump assembly. It addresses common failure modes such as shaft seal leakage or loss of prime due to air ingress. For industrial maintenance teams, keeping this repair set in stock ensures minimal downtime for critical welding automation or manual stations dependent on water cooling.
