Job Description

Industrial Pump Rebuild Mechanic

At Hydro Inc., you’ll help keep industry moving. From our Aftermarket Pump Repair Shop in Chicago’s West Loop, you’ll bring worn pumps back to life, solve tough field problems, and contribute to a mission that has guided us since 1969: partnering with customers worldwide to boost reliability and performance through unbiased engineering, quality workmanship, and responsive service.

A day in the West Loop

You clock in, review work orders, and dive into diagnostics on a mixed lineup—centrifugal pumps, compressors, even the occasional small turbine. With prints and OEM specs in hand, you tear down methodically, measure precisely, and build back better. Some days you’ll be on-site at a customer facility, troubleshooting under pressure; other days you’ll be leading the shop floor when your supervisor is out, coordinating repairs and keeping safety first.

What you’ll tackle

• Diagnose, disassemble, repair, and rebuild a wide range of pumps, compressors, and small turbines.
• Perform field assessments and on-site repair work when needed.
• Operate shop equipment: steam cleaner, sandblaster, bead blaster, cranes/hoists/come‑along, forklift, pullers/presses/rams, ovens/heaters, and impact tools.
• Handle maintenance welding as part of repair workflows.
• Serve as lead in the supervisor’s absence and foster effective working relationships across the team.

Your toolkit and approach

• Comfort with grinders, heating torches, drill press, balance machine, radial drill, and burning torch.
• Expert use of precise measuring tools; assemble rotors by hand fitting using die grinders.
• Follow written and verbal instructions, including manufacturer service specifications.
• Clear, professional communication—written and verbal.

What you bring

• 5+ years as a pump mechanic, including shop repair and the assembly/disassembly of pumps, valves, and rotating equipment.
• Proficiency in acetylene and electric arc welding.
• Knowledge of methods, materials, tools, and techniques used in pump repair and maintenance.
• Hands-on experience with power/hand tools and diagnostic equipment.
• Background as a millwright mechanic or formal training from an accredited technical college/trade school, or a comparable multiyear apprenticeship.
• Working knowledge of electric motors.
• Journeyman status or U.S. Military experience desired.
• High school diploma required.
• Preferred: 2 years’ machining and tooling experience in a machine shop environment.

Physical requirements

Ability to safely lift and handle items up to 60 lbs.
