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

Keep Your Torch Cool and Your Welds Hot

If your water cooler is making strange noises, losing pressure, or failing to keep your torch cool, it might be time to swap out the pump. The ESAB 0558004062 is the heavy-hitter replacement pump you need to get your system back to 100%. We all know that a water-cooled torch is a lifeline when you are pushing high amps on aluminum or running long beads on heavy steel. Without a reliable pump pushing that coolant through the lines, you risk frying your power cable, melting your torch head, and halting production instantly.

This isn't just any pump; it's a rotary vane workhorse set to 115 PSI. Why does that matter? Because your torch lines are long and the passages inside the head are tiny. You need that 115 PSI of pressure to force the coolant through the system efficiently. A weaker pump might move water, but it won't scrub the heat away fast enough to protect your consumables and power cable. With 100 gallons per hour of flow, this pump cycles your coolant tank fast enough to ensure the liquid going into your torch is actually cool, not lukewarm.

Installation is straightforward for those familiar with cooler maintenance. It's built with a brass body, so it's tough enough to handle the shop environment and resistant to corrosion from the coolant. Don't wait until your flow alarm trips or your torch handle gets too hot to hold. If your current pump is showing signs of wear—like leaking or pressure drops—swapping it out with this genuine ESAB unit is the cheapest insurance policy you can buy for your welding rig.

Why Welders Choose This Pump:

• Reliable Pressure: Keeps the flow alarm off and the coolant moving.
• High Volume: 100 GPH means maximum heat removal.
• Tough Build: Brass construction stands up to daily use.
• Direct Fit: Made for your ESAB cooler, so no hacking required.
