            • Packing

              Chesterton® advanced packing uses the latest in fibre, lubricant, and braiding technology to deliver superior leakage control. Our fibres are individually coated with lubricant before braiding, thus eliminating wicking and providing superior blocking for longer, leak-free performance and lower life-cycle costs for your valves and pumps.

              With a state-of-the-art valve testing facility, Chesterton® conducts both API and ISO test protocols and provides a wide range of services to many valve manufacturers. With the ability to simulate many critical applications, we can help you choose the right valve and packing for your needs.


              Many factors must be considered when choosing the proper gasket for an application, including safety, temperature, pressure, the media to be sealed, equipment conditions, the versatility of the product, and cost. Chesterton’s wide range of gasket products means we can address flange sealing needs from water to critical high-temperature, high-pressure process conditions.

            • Rotating Equipment Sealing Solutions

              Condensate return pumps can be difficult sealing applications due to high temperatures, flashing conditions, and the lack of a reliable cooling water supply.
              In a U.S. papermaking facility, compression packing was used to seal these pumps. Stuffing box temperatures were reaching 180o C (350o F) and flush water availability was intermittent, causing premature packing failure. The mill was replacing packing every 3 to 10 weeks on these pumps.
              Conventional mechanical seals were tested, but steam flashing through the seal faces caused face damage and eventual seal failure.

              Chesterton 180H Cartridge Seal is the sealing solution for applications where flashing can occur, external cooling is limited or unavailable, or where pressure has a tendency to distort the seal faces. Hydropad Geometry Enhances Face Lubricity This seal is designed with an advanced hydropad geometry seal face that improves film formation between the mechanical seal faces and significantly enhances face lubricity. This increased film formation reduces heat generation and increases seal life in many applications. Problems with Cooling Systems? This paper mill did not have external cooling capabilities and used a Chesterton 180H Cartridge Seal with a Plan 11 discharge recirculation piping plan.

              Increased Mean Time Between Failures
              This paper mill significantly improved their seal reliability from weeks to years with the Chesterton 180H Cartridge Seal.
              The plant converted all 5 of their condensate return pumps to Chesterton 180H Cartridge Seals with exceptional results!
            • Digester Bottom Scraper

              The Challenge
              A Pulp Mill experienced severe problems with many of the applications in the Digester Area. Particularly the bottom scraper on the main Digester Vessel exposed to be a tough application to seal.
              In particular the combination of high pressure and high temperature forms a tremendous challenge as far as sealing technology is concerned.
              The plant tried to solve the problem with various types of packing but most of them gave too much consolidation.

              The Chesterton Solution
              After various experiments the plant is now using a combined packing solution made up out of a Sandwich of 1830SSP and 477-1T.
              This customer is giving him so far the reliability that he needs to run his plant effectively.

              Why Use This Solution?
              • Repeatable, predictable, lasting sealing performance
              • Improved Safety
              • Minimize Costly, Unplanned Maintenance
              • Improved Asset Management
            • Rotating Equipment Sealing Solutions

              Due to severe conditions in the stuffing box, the packing set leaked often. The equipment’s water consumption was very high. Because of environmental regulations, all injected water had to be removed from the process and treated as industrial waste water. This was a costly and energy-intensive process.
              Help MDF manufacturer extend maintenance cycles on their Sunds defibrators and reduce water/energy costs.

              A 3-Ring Chesterton 1730 Packing Set combined with SpiralTrac.
              ■ In a traditional packing set consisting of 5 or more rings, the gland load gets mainly transferred onto the first few packing rings. The rings at the bottom of the stuffing box receive very little of the gland force
              ■ The SpiralTrac Environmental Enhancer fills up the rest of the stuffing box. Because of its unique and patented design, it directs solid particles away from the packing set, assuring a prolonged life of the set

              ■ The flush rate was reduced to a controlled 5.5 liters/minute
              ■ Leakage was reduced considerably — extending maintenance cycles and the life of the defibrators
              ■ When the packing set needs to be replaced, only the 3-ring packing set needs to be exchanged. The SpiralTrac can be re-used
              ■ Reduced maintenance and downtime

            • Challenge

              A customer was using a competitor’s packing on an agitator in a chemical application. The packing wore down the sleeve, requiring replacement wore down the sleeve, requiring replacement of both packing and sleeve every three months.
              Sleeve Cost: $500 every 3 months = $2,000/year
              Competitor Packing cost = $1,000/year
              Labor Cost = $1,600/year
              Total Cost = $4,600/year
              Increase time of continuous service to support plant cycle and reduce costs.

              • Chesterton DualPac® 2211, a braided packing that brings together the best of aramid and PTFE packing with distinct shaft-facing and outward-facing benefits as shown on Figure 1.
              • Five rings of Dua/Pac 2211 were installed as shown in Figure 2 for solids resistance. With the DuaiPac 2211 aramid side against the bottom of the stuffing box, you achieve resistance to extrusion and solids yet there is minimal contact between the aramid and shaft This untae ability reduces shaft wear and increase uptime.

              Client Reported
              • Improved packing has lasted over six months and the sleeve wear is not an issue
