The main cause of failure of a hydraulic circuit is the presence of free-flowing particles in the hydraulic fluid.
These particles are generated either by maintenance operations or construction of hydraulic networks (silica, textile fibres, filings …) or by the destruction of operating bodies such as the pumps, valves …
Hydraulic cleaning consists of eliminating pollutants by closed-circuit high-speed circulation in the networks through filters with a filtration threshold chosen based on the level of cleanliness required.
Monitoring the effectiveness of hydraulic flushing is carried out either continuously with an electronic particle counter (according to standards NAS 1638 and ISO 4406) or by analysing a sample by microscope counting (according to standard NF48651).
Hydrochem has several independent filtration units tailored to our clients’ facilities. These units are equipped with 3m filters and have a capacity of 200 L/minute at 53 bars up to 2600 L/minute at 12 bars.
