Kidney Loop Filtration: A Practical Guide for UK Hydraulics
A maintenance engineer draws an oil sample from a 200-litre hydraulic power unit after another bout of erratic servo-valve behaviour. The laboratory result returns ISO 22/20/17, well above the 18/16/13 cleanliness target expected downstream of precision valves. The...
Hybrid Power Solutions for Industrial and Mobile Hydraulics
A hydraulic power pack can be correctly rated on paper and still waste energy every time the machine pauses. A fixed-speed motor keeps turning, a pump keeps producing flow, and the relief valve converts surplus hydraulic power into heat while the cylinder waits for...
What Causes Pump Cavitation: Physics, Symptoms
A pump that suddenly sounds like it's processing gravel usually gets blamed for being worn out. The operator may notice heavier vibration, a fluctuating pressure gauge or a loss of flow, then find that a recently replaced pump has developed the same fault. In...
What Is Preventive Maintenance and Why It Matters
Preventive maintenance is a planned, scheduled approach to inspecting, servicing and replacing equipment components before they fail, designed to reduce unplanned downtime and extend asset life. The National Audit Office identified a minimum UK government estate...
Pulsation Dampening in Hydraulics: A Practical Guide
The operator feels it before the fault code appears. A telehandler's steering wheel starts to buzz as engine speed rises, the hydraulic hoses chatter against their clamps, and the pressure gauge needle refuses to settle. On a factory floor, a press may bang on...
Sustainability Practices for Hydraulic Systems That Work
A maintenance engineer arrives at a Yorkshire plant and finds a hydraulic power pack running hot, a pump shaft seal weeping, and a system using roughly 30 litres of ISO VG 46 fluid every quarter. Production still runs, so the fault has been treated as routine...
Gearbox Motors: A Practical Guide to Selection and Use
A conveyor on a Midlands food-production line starts tripping whenever the product load rises. The motor nameplate appears adequate, yet the shaft slows, the gearbox runs hot and the maintenance team is called back to the same fault. The problem may not be a defective...
Mobile Plant Maintenance: Essential Tips for 2026
In the UK, one in three workplace deaths was attributed to unsafe maintenance in 2009/2010 under Northern Ireland safety guidance, a reminder that servicing is a control for life-critical risk, not an administrative chore. The danger is particularly clear around...
