FLUSHING

All hydraulic systems need to be flushed prior to operation to remove incidental fabrication debris. It is important to recognize the limitations that exist when using a lubricant to attempt to remove such debris. This will help avoid catastrophic failure associated with debris being left in the system.

There are two types of debris that will damage systems. The first is incidental fabrication debris. By designing the system so that all portions of the system achieve the desired flow rate, the fabrication debris will be rapidly flushed away.

The second type of debris is caused by corrosion. The use of black or pickled pipe and fittings in the construction of the system is the source of this contamination. As will be explained in the next section, if you build corrosion into your system, no amount of flushing will remove the debris. As the metal in your pipe and components continue to degrade, debris will be entering your system to foul filters and damage sensitive valves.

Recognizing the true limitations that ordinary flushing suffers provides insight into why many systems that use pickled pipe fail even after extensive flushing. Avoiding electro-chemically bonded corrosion in your system is a basic requirement. With our adherence to standards that are written by and for the hydraulic industry, a satisfactory flush and a properly operating system is yours as easily as specifying REDOX.
