Here you will find descriptions of our industry terms for reference.
A filter that cleans hydraulic fluid by using a medium to trap and hold contaminants by mechanical means.
A filter that cleans hydraulic fluid by using a medium to trap and hold contaminants by molecular means.
Foreign, undesirable materials carried into the liquid or air of a fluid power system: dirt, water, paint, metallic particles or other materials that are ingested during equipment operation.
Methods used to clean and maintain fluids at an acceptable operating temperature in a hydraulic or pneumatic system.
Hydraulic fluid filtration system that filters all pump output before returning it to the system reservoir.
Hydraulic fluid filtration system that continually pumps fluid out of the reservoir and through a filter before pumping it back into the system reservoir.
Hydraulic fluid filtration system that continually pumps a measured amount of system fluid to the filter and then returns it to the system reservoir.
Did You Know…
- When exposed to high operating temperatures, hydraulic fluids oxidize creating a varnish. This varnish promotes the formation of sludge and contributes to corrosion of internal metal surfaces.
- Up to 75% of most hydraulic system failures can be traced to system fluid contamination.
- The sources of hydraulic system contaminants include introduction during the manufacturing process, during operation, from breakdown of hydraulic fluid or from equipment component wear.
- Hydraulic fluid contaminants reduce the fluid’s ability to lubricate, seal clearances and to transfer heat or energy. They also increase excessive wear of internal components within the system.
- Too high or too low temperatures can impact hydraulic fluid performance. For most systems, the optimal reservoir oil temperature is between 110°F and 140°F.
- Elevated hydraulic system operating temperatures can be designed to balance the rate of system heat input by allowing heat reduction through Conduction, Convection or Radiation.
