Here you will find descriptions of our industry terms for reference.

Absorbent Filter

A filter that cleans hydraulic fluid by using a medium to trap and hold contaminants by mechanical means.

Adsorbent Filter

A filter that cleans hydraulic fluid by using a medium to trap and hold contaminants by molecular means.

Contaminant

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.

Fluid Conditioning

Methods used to clean and maintain fluids at an acceptable operating temperature in a hydraulic or pneumatic system.

Full-Flow Filtration

Hydraulic fluid filtration system that filters all pump output before returning it to the system reservoir.

Off-Line Filtration

Hydraulic fluid filtration system that continually pumps fluid out of the reservoir and through a filter before pumping it back into the system reservoir.

Proportional Filtration

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.
