Table notes
1. An external flush is required on low pressure systems that contain a high concentration
of abrasives.
2. Use packing on open or closed systems which require a large amount of makeup
water, as well as systems that are subjected to a wide variety of chemical conditions
and solids buildup.
3. For operating temperatures above 250°F, a cooled flush is required and is
recommended for temperatures above 225°F for optimum seal life. On closed
systems, cooling is accomplished by inserting a small heat exchanger in the flush line
to cool the seal flushing fluid.
4. Flush-line filters and sediment separators are available on request.
5. Use a standard seal on closed or open systems that are relatively free of dirt and/or
other abrasive particles.
