Flushing is not a simple task. The flushing fluid must be the right product and used at the right temperature and flow rates to assure cleanliness and passivation.

Flushing Fluids - Great care must be taken in choosing the solutions used to flush a system. Specific products must be used to accomplish the preparation of the internal surfaces according to the use of the system.

Fluid Temperatures - The proper fluid temperature is necessary to assure contaminates are softened to the point they will detach from their hiding places and be carried to the filtration media.

Flow Rates - High flow rates are necessary to dislodge foreign particles and have them carried away by the flushing fluid.

Passivation - This is where the bare materials are treated so that they have an initial reaction to the metals of the walls of tubes and reservoir so that an oxide patina can form to shield the metal from unwanted chemical reactions later.

If flushed properly, a hydraulic system starts off with no contaminates to foul the system later.

At this point it would prudent for the client to examine the F.I.V.E. Program offered by FPI. This program is a comprehensive plan to build quality and reliability into the fluid power system for better performance with less downtime. This program offers a way to sustain the fluid power system throughout the life cycle with improved maintenance policies, sustained clean fluid, and systematic inspections. With the system being broke open for flushing, it would be an excellent time to add the value for future maintenance.
