Water is everywhere!

FPC water removal filters – available in both spin-on and cartridge style

  • Reduction of costly downtime and replacement of failed components.
  • Less component wear, less component-generated particulate contaminants.
  • Reduced chance of catastrophic failure.
  • Less frequent replacement and disposal of contaminated fluid.
  • Increased efficiency of the system, improving productivity.

Did you know? As little as 300 ppm of water can saturate a hydraulic fluid. Many mineral oils and synthetic fluids, unless specifically filtered or treated in some way, will contain some level of water above their saturation point.

Removing water. Using a water removal element is an effective way of removing free water contamination from your hydraulic system. The filter media is a highly absorbent copolymer laminate with an affinity for water. The water is bonded to the filter media and removed from the system.

 Storage and handling

Fluids are constantly exposed to water and water vapor while being handled and stored. Outdoor storage of tanks and drums is common. Water settles on top of tanks and drums and infiltrates the container, or is introduced when the container is opened to add or remove fluid. Another source of water in hydraulic fluid comes from water vapor in the air entering the tank as it breathes. The water vapor condenses inside the tank as temperatures drop and contaminates the fluid. This can be a major problem in areas of high humidity.

In-service. Water can get by worn cylinder and actuator seals, or through reservoir openings. Water can come in contact with these entry points through water based cutting fluids or when water and/or steam are used for cleaning.

Water generated damage and operating problems

  • Corrosion
  • Accelerated abrasive wear
  • Bearing fatigue
  • Additive breakdown
  • Increased acid level
  • Viscosity variance
  • Electrical conductivity

Bacterial growth as a contaminant. Once water enters a system, growth of micro- organisms begins. Once micro-organisms start growing, they keep growing. Evidence of bacteria growth can be seen as slime in the hydraulic system, the apparent increase in viscosity of the fluid, and odors and discoloration of the fluid.

Testing your fluid for water . A simple test will tell you if there is water in your fluid. Place a small amount of fluid into a metal dish or spoon. Apply a flame under the container with a match. If bubbles rise and `crackle’ from the point of applied heat, you have free water.
