What Is Pump Cavitation: The 2026 Engineer’s Guide

Pump cavitation is a damaging process where low pressure at the pump inlet causes vapour bubbles to form in the hydraulic fluid and then violently collapse, eroding internal components. In practical terms, cavitation starts when NPSHa falls below NPSHr, and accepted...

Hydraulic Accumulator Sizing: Formulas & Selection 2026

You're usually looking at accumulator sizing because something in the machine isn't behaving as it should. A press bangs harder than expected at changeover. A lift circuit drifts. A clamp loses confidence at the worst point in the cycle. Or procurement has...

Hydraulic Pumps and Motors: UK Engineer’s Guide 2026

If you're specifying a new machine, replacing a failed unit on a loader, or trying to stop a hydraulic pack from running hot for no obvious reason, the same two questions usually land on the bench first. Have we chosen the right pump and motor, and are we looking...
Directional Control Valves: A Complete UK Guide

Directional Control Valves: A Complete UK Guide

A machine rarely gives you much warning when the wrong valve is in it. A loader gets lazy on one function. A press hesitates between strokes. A tipping body drifts when it should hold. The pump gets blamed first, then the cylinder, then the oil. Quite often, the...

Manifold Block Design: A Practical UK Guide

If you're looking at a hydraulic power unit, mobile machine, or OEM assembly and seeing hoses crossing over each other, fittings tucked into awkward corners, and valves mounted wherever there was room, the problem usually isn't just appearance. That layout...
