Hydraulic Hose Inspection and Replacement Guide
Hydraulic hoses are critical components in any hydraulic system, and regular inspection is essential to prevent costly failures and downtime. At Mercury Hydraulics, we recommend a systematic approach to hose inspection and timely replacement to keep your equipment operating safely and efficiently.
Regular visual inspections should be performed daily or before each use of hydraulic equipment. Look for signs of wear including abrasion, kinking, crushing, or damage to the outer cover. Any hose showing exposed reinforcement wire, blistering, or soft spots should be replaced immediately. Even minor damage can lead to catastrophic failure under operating pressure.
Hydraulic hose failures are one of the leading causes of equipment downtime. A proactive replacement schedule based on manufacturer recommendations and operating conditions can prevent 90% of hose-related failures.
When replacing hydraulic hoses, always use hoses rated for the correct working pressure and temperature range of your system. Mercury Hydraulics stocks a comprehensive range of hydraulic hoses in SAE, DIN, and EN standards, with custom assembly available for non-standard applications. Our technicians can fabricate replacement hoses to exact specifications while you wait.
Proper installation is just as important as selecting the right hose. Avoid twisting hoses during installation, ensure adequate bend radius is maintained, and use appropriate clamps and supports to prevent chafing against other components. After replacement, always pressure test the new hose assembly before returning equipment to full service.

Hydraulic Pump Troubleshooting: Diagnosing Common Problems
A hydraulic pump is the heart of any hydraulic system, converting mechanical energy into hydraulic flow. When problems arise, diagnosing the root cause quickly can mean the difference between a minor repair and a complete system overhaul. Mercury Hydraulics’ certified technicians have decades of experience diagnosing and repairing hydraulic pumps across all major brands and applications.
The most common symptom of pump trouble is reduced system pressure or flow. If your equipment is moving slowly or struggling to lift rated loads, start by checking the hydraulic fluid level and condition. Contaminated or degraded fluid is responsible for a significant percentage of pump failures. Dark, milky, or foamy fluid indicates contamination and requires immediate attention before further diagnosis.
Unusual noises such as whining, cavitation, or knocking are reliable indicators of pump problems. Cavitation — caused by insufficient fluid supply to the pump inlet — produces a characteristic grinding or rattling sound and can rapidly destroy pump internals. Check suction line restrictions, filter condition, and fluid viscosity if cavitation is suspected.
Excessive heat generation is another warning sign that should not be ignored. While some heat is normal in hydraulic systems, fluid temperatures above 180°F (82°C) indicate a problem such as excessive internal leakage, relief valve bypass, or inadequate cooling. Mercury Hydraulics offers complete pump testing services to accurately measure volumetric efficiency and identify internal wear before catastrophic failure occurs.
