Custom-made ring sets for pumps, agitators, valves and reciprocating equipment.
Because of the friction along the shaft and bore of the stuffing box, the mechanical pressure exerted by the bland is not transmitted uniformly across all the rings. In conventional packing methods, the first two rings absorb most of the mechanical pressure; therefore they receive the most wear and in turn exert the most wear on the shaft. In fact, 70% of the wear takes place here. But, with Sepco’s Die-Formed rings, the mechanical pressure is exerted over a larger area, greatly increasing shaft sleeve life. Die-Formed rings are densified, “run-in” time is greatly reduced and sealability is much better resulting in longer packing and sleeve life.
