Repairs, defective seals or a faulty tank seal can allow dust and metal or seal particles to enter the hydraulic system or oil tank. From there it gradually spreads throughout the entire system and damages components such as pumps or valves. The consequences: repairs, breakdowns and long downtimes. In addition to regular oil analyses, the choice of the right filter system is of great importance. Whether a suction, pressure, return or tank vent filter: there are numerous filtration solutions for a wide range of purposes. The HANSA-FLEX fluid technology experts will advise you on their selection, design and installation.

Oils with a high level of dirt also carry hidden dangers. Many particles are often not visible to the naked eye. The consequences: even the smallest particles circulating undetected inside your system can lead to wear, abrasion and corrosion. It is only a matter of time before components fail suddenly. To prevent damage from progressing this far, the HANSA-FLEX fluid experts analyse the oil on site or in the laboratory. And what if a failure has already occurred? As part of damage detection on defective components such as pumps, motors and hose lines, we draw up a list of optimisation measures for the hydraulic system, hydraulic and gear oils, which we are happy to carry out for you.

If the oil analysis finds foreign matter, the HANSA-FLEX Fluid Service can filter the fluid while the system or machine continues to run. We provide various high-performance filter systems and flushing equipment for hire or purchase. We also design and produce flushing units and bypass filter systems to suit your specific requirements. These can be a permanent part of your system. Before an oil change and before initial commissioning, our Fluid Service technicians thoroughly flush your system so that no harmful contaminants remain.

Even fresh oil is not 100% clean. Residues from manufacturing, filling or transport may remain. The levels of contamination may be only slightly better than the specified minimum ISO requirement 21/19/16. This is not sufficient for sensitively designed hydraulic systems, because even the smallest amounts of dirt in the micrometre range can lead to serious problems. Highly sensitive hydraulic systems in machinery and plant engineering equipment require special fluid care. If necessary, the fluid experts from HANSA-FLEX carry out microfiltration of the oil before filling and officially record compliance with the required level of cleanliness.
