Chesterton’s SuperSet has been specifically designed to increase packing and equipment service life while dramatically reducing flush rates. It combines the sealing capabilities of the company’s Mechanical Packing products (including enhanced performance, sealibility, leak prevention, chemical compatibility, strength, toughness and thermal characteristics) with the patented design of the EnviroSeal SpiralTrac™ Version P Environmental Controller for Packed Stuffing Boxes.
The SpiralTrac Version P enhances the utilization of the flow and centrifugal effects around the shaft by performing like a centrifugal separator. The built-in tangential lantern ring and helical grooving system impart motion to the flush, and the resulting centrifugal force throws the particulates in the fluid to the outside of the bushing. The SpiralTrac grooving system then hydrodynamically pumps the solids to the bottom of the stuffing box and back into the pump casing.
