hydraulikcheck

Hydraulikcheck is a term used in German-speaking contexts to describe a service process for inspecting and testing hydraulic systems, including fluids, components, and control hardware, to verify performance, safety, and reliability.

The scope covers hydraulic power units, pumps and motors, actuators, valves, hoses and fittings, reservoirs, and filtration and cooling components. It may be performed on new installations, during routine maintenance, or after repairs to detect leaks, wear, or contamination.

Typical procedures include a visual inspection; leak detection; fluid level, color, odor and condition assessment; contamination analysis (particle count and water content); viscosity checks; and pressure and flow tests. On-site diagnostics can use pressure gauges, flow meters, infrared thermography, and portable analysers; all findings are documented.

A hydraulic check aims to extend component life, reduce downtime, ensure safe operation, improve efficiency, and support regulatory compliance. It is commonly used in manufacturing, construction, agriculture, and machinery service sectors, often as part of preventive maintenance programs.

Standards and guidance for hydraulic safety and performance, such as ISO 4413, inform the practice, while service providers may accompany checks with action plans, maintenance recommendations, and follow-up testing.
