Pump Repair

Regardless of the complexity or specific design of your hydraulic system, one component is almost always essential: the hydraulic pump.

Unfortunately, due to its critical nature, hydraulic pumps are also the part of a system most likely to cause an overall failure; they’re the most subject to wear and tear and can be the cause of both gradual and sudden system shutdown.

Pump Repair & Servicing from Metro Hydraulic Jack Co.

Since 1941, the Metro Hydraulic team has offered expert hydraulic pump repair, diagnostics, and rebuild services for piston pumps, vane pumps, gear pumps, and more; our team can evaluate a failing hydraulic pump either in our fully equipped on-site shop or on location at the source of the problem. Some of the many problems we work to diagnose and repair include:

• Pump suction strainer blockage and varnishing
• Air breather clogging
• Oil misuse, leakage, and viscosity issues
• Restricted or clogged pump inlet plumbing
• Bent or collapsed hoses
• Sludge and blockage buildup
• Failing or incorrectly sized suction strainers
• Entrapped air in a system
• Worn or broken pump shaft seals
• Pump inlet line leaking and joint failure

Industries and Applications

Our professional technicians serve projects large and small in a wide range of industries, including:

• Automotive presses, compressors, and cylinders
• Heavy equipment and construction tools
• Industrial motors and pumps
• Material handling tools, lifts, and conveyors
• Mobile cylinders and compact systems
• Railroad equipment

Common Hydraulic Pump Problems

Pump trouble can be sudden, but it can also be indicated by several common symptoms. Below are some of the most common signs of a struggling pump in hydraulic systems.

• Increased system heat or overheating
• Increased operating noise
• Difficulty or inability to develop appropriate output
• Erratic cylinder operation
• Decreased cylinder speed
• Decreased hydraulic motor speed
• Overall system failure
• Milky oil appearance

Many of the problems above can be indicative of an air leak, water leak, or oil leak in the pump. Pump cavitation, or the inability of the pump to draw its full charge of oil, can also cause several of these symptoms.

Why Prompt Repair Matters

Hydraulic pumps are the heart of your equipment, and delaying repairs can quickly turn a minor issue into a costly breakdown. Acting early offers several benefits:

• Prevents Costly Downtime – When a pump fails unexpectedly, operations grind to a halt. Timely repair helps avoid production losses and missed deadlines.
• Extends Equipment Life – Addressing problems such as leaks, seal wear, or pressure fluctuations reduces strain on the pump and connected components, keeping your system running longer.
• Maintains Safety – A failing hydraulic pump can cause unstable equipment performance, which may lead to safety hazards. Regular maintenance and fast repair protect both operators and machinery.
• Improves Efficiency – A pump operating at peak condition ensures proper pressure and flow, helping equipment perform consistently while using less energy.
• Reduces Long-Term Costs – Repairing a pump at the first sign of trouble is far less expensive than replacing it after catastrophic failure.
