In high-pressure systems, CAT pumps are renowned for their durability and performance. But even the toughest pumps wear over time. Whether it’s a worn seal, pressure loss, or a system fault, CAT pump repair is crucial for keeping your operation flowing without downtime or costly replacements.

At MultiTorque, we specialize in CAT pump repair, parts replacement, and full system servicing across Australia. With workshops in Perth and Brisbane, we provide quick turnarounds, mobile repairs, and expert advice—so you’re never left under pressure.

Why CAT Pumps Fail—and Why You Should Act Fast

CAT pumps are designed for rugged performance. But even the best equipment needs regular servicing and attention. Common causes of CAT pump issues include:

• 🔧 Seal failure from prolonged high-pressure use
• 💦 Leaking oil or water due to worn plungers or crankcase damage
• 🚫 Low pressure output caused by faulty valves or air entrainment
• 🔥 Overheating from lubrication issues or pump over-speeding
• 🧪 Corrosion or abrasion from harsh chemicals or abrasive fluid media

Delaying a minor repair can result in full system failure—and that means production downtime, safety risks, and higher long-term costs.

Preventative Maintenance = Long-Term Savings

Regular servicing reduces the likelihood of catastrophic failure and keeps your equipment running longer. Our CAT pump maintenance packages include:

• Monthly or quarterly seal inspections
• Scheduled valve and plunger service intervals
• Oil changes and crankcase flushing
• Pressure calibration and flow testing
• Fleet-wide health checks for multiple units

Preventative maintenance is cheaper than emergency repair—and way cheaper than total replacement.
