The Key to a Leak Free Hydraulic System

Slow leaksHydraulic oil leaks are often considered to be an inherent characteristic of hydraulic machines. While this may have been true 30 years ago, advances in sealing technology and the development of reliable connection systems means that today, leak-free hydraulic plumbing is readily achievable.

Reliable Connections

Leak-free reliability begins at the design stage, when the type of hydraulic fitting is selected … Read more

Case Drain Flow and Hydraulic Pump and Motor Efficiency

big question markOne of our readers wrote me about the following problem:

“I tried one afternoon and evening to determine what was wrong with a hydrostatic transmission by monitoring case drain flow. I was confused by the readings I was seeing. There was a flow meter in the transmission pump outlet and another in its case drain that always showed charge pump … Read more

Make Sure You Do This When Replacing a Hydraulic Hose

hydraulic hoseThe hydraulic hose fabrication process – or more specifically – the hose cutting process introduces contamination. This comprises metal particles from the hose’s wire reinforcement and the cutting blade itself, and polymer dust from the hydraulic hose’s out cover and inner tube.

The amount of contamination which enters the hose during cutting can be reduced by employing techniques such as … Read more
