Bell & Gossett P2000452 Series 580 - Manual (Page 12)

1. An external flush is required on low pressure systems that contain a high concentration of abrasives.
2. 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.
3. Flush-line filters and sediment separators are available on request.
4. Use a standard seal on closed or open systems that are relatively free of dirt and/or other abrasive
particles.
