System Efficiency in Hydraulics: A Practical Guide

The UK's energy use per unit of GDP has fallen by about 52% since 1980. GDP more than doubled, while primary energy consumption rose by only around 2%, according to the UK government's energy-efficiency statistical summary. That national improvement can...

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...
