  • Roll on, Roll on, Roll on – with Chesterton® Advanced Bearing Reliability Programs

    Roll on, Roll on, Roll on – with Chesterton® Advanced Bearing Reliability Programs

    Modern paper machines are up to 150 meters long, 10 meters wide and run at speeds of up to 2000 meters per minute. Huge giants, 24/7 in operation, programmed for smooth production without downtime. Outside of the paper machine itself there is a complex process including the wood yard, stock preparation, pulping and paper conversion.


    The operational challenges of the pulp and paper industry are complex. The production process is demanding, and equipment is constantly exposed to a humid and chemical-laden atmosphere. Without suitable lubricants, damage occurs to rotating machinery, which in the worst case can bring the entire plant to a shutdown and result in extremely high maintenance costs. Maximizing the Mean Time Between Failures (MTBF) is essential to optimize the production process and profitability.

    Defying all challenges – Chesterton® Advanced bearing lubrication

    Lubricants are required to deliver top performance in the pulp and paper industry, as they have to perform reliably under harsh environmental conditions such as moisture, dust, contamination, chemicals, temperature, pressure or vibration. In these aggressive conditions, high performance lubricants and maintenance products help to keep machines running reliably and trouble-free, prevent premature equipment failure and thus increase plant productivity.

    For these demanding applications, Chesterton provides lubrication products for chains, bearings, wire ropes, cables, open gears, pneumatics and sliding lubrication.

    In this article, we focus on bearing lubrication, which plays a crucial role in the pulp and paper industry.

    Chesterton Industrial Lubricants prevent from corrosion

    As a lubricant manufacturer, what special factors do we consider when developing bearing lubricants? What special benefits do our products offer paper mills?

    • “Water and moisture” factor in paper mills – risk of bearing corrosion and wear
      Conventional elastomer lip seals for equipment bearings are designed to prevent the ingress of water and moisture. However, their service life is limited, and reliable sealing diminishes after approx. 3000 operating hours. If these simple lip seals fail, water from the environment ingresses into the bearing housing and the grease can be washed away. Grease being washed away is a concern, but even more concerning is, with what it is replaced with, water!!!
      Constant lubrication is now interrupted and bearing wear is accelerated by friction and corrosion. This reduces the service life of the bearing and leads to premature failure. Chesterton’s advanced sulfonate complex technology shows best in class water washout resistance and corrosion protection. This high performance can be seen in tests according to ASTM, ISO and DIN standards. You can find the test results on our product data sheets – feel free to compare them with those of our competitors.
    • “Load and vibration” factor – risk of bearing damage
      Bearings are among the most important components of rotating equipment and electric motors. High speeds, heavy loads, high operating temperatures, start/stop function, high vibrations in rotating equipment – all these factors push bearings to their limits. Many customers replace the bearings on their equipment due to damage caused by wear and vibration. Chesterton lubricant technology contains advanced lubricity and extreme pressure additives that enhance grease performance in these challenging conditions for both, equipment and electric motor bearings. As with the “water/moisture factor”, there are standard ASTM, ISO and DIN tests to measure the performance of greases to help customers select the best product for their application.
    • The “human” factor in paper mills
      Another factor that has not been addressed yet is the “human factor”. Timely manual lubrication often is not carried out consistently or regularly during the operational process. This can lead to over- or under-lubrication. Over-lubrication means excessive consumption of lubricants, is therefore uneconomical and can cause temperature build up, which reduces the lifetime of the grease and can lead to premature failure of the bearing. Under-lubrication can lead to system failure in the long term. Automatic programmable lubrication systems for grease and oil, such as the Chesterton Lubri-Cup™ dispenser, help ensure a regular and timely supply of lubricants.

    Continuous lubrication with Chesterton Lubri-Cup™ Lubricant Dispenser means optimum bearing performance and increased work safety

    Our Chesterton Grease Lubri-Cup automatic lubricator provides the right amount of lubricant when required. It helps extend bearing lifetime and reduces bearing maintenance. As the name suggests, lubrication runs automatically with the right grease, at a constant interval with the correct amount of lubricant. Our “Stories of Success” result in longer service life of the bearings and an immense extension of the MTBF.

    Here is one of our success stories:

    “Our Lubri-Cups were used in a plant with over 7000 electric motors. The customer had a vibration monitoring program in place but found that some critical motors were experiencing excessive vibration causing premature bearing failure. The customer decided to run a test using Chesterton 638 Electric Motor Grease. Immediately after applying 638 EMG into the bearing housing, a reduction in vibration was visible. As a result of the test, the customer decided to use Chesterton 638 EMG as the standard grease for all electric motors. Other benefits for the customer included reducedgrease consumption and an increase in bearing lifetime. One of the reasons for the success of the 638 EMG was due to its additive plating technology called QBT (Quiet Bearing Technology). This helps fill any surfaceirregularities or damage on the bearing surface and allows the bearing to run more smoothly and quietly.“

    Chesterton® High-Performance-Grease for bearing lubrication under extreme conditions

    From our extensive portfolio of industrial lubricants, we focus on our high-performance greases 615, 617(E) and 638 EMG for the pulp and paper industry. These greases are specifically designed for heavy loads and high temperature applications in wet, corrosive environments. They are used in various equipment in many industries and offer outstanding performance for the lubrication of machine bearings.

    Benefits include:

    • Less grease washout, therefore lower grease consumption and lower acquisition costs. Elimination of bearing failures due to corrosion.
    • High lubricity, extreme pressure performance – resulting in longer bearing lifetime and reduced downtime.
    • Thermal and shear stability – elimination of oil bleed from grease and hardening in the bearing.  

    Bearing protection at its best – our lubricants and polymer seals

    Chesterton also offers advanced bearing sealing solutions in the form of our Polymer Labyrinth Seal (PLS), which provides protection for the bearing and offers customers a significant advantage over conventional lip seals in terms of service life. In addition, this solution is available in a split design, which allows for easy installation.

    Conclusion

    The pulp and paper industry has very special requirements for machine bearings. The advanced lubricants from Chesterton help against “bearing killer” conditions such as corrosion, grease washout, load and vibration and make a considerable contribution to a long bearing life.

  • Production Efficiency and High Pump Reliability thanks to Innovative Packing Technology

    Production Efficiency and High Pump Reliability thanks to Innovative Packing Technology

    Paper and pulp production is an extremely demanding industry. It is a long way from the processing of raw wood to the production of fine writing paper. In many manufacturing steps, the abrasive raw material is processed with hot water and chemicals. This means that all machine components need to be highly resistant to wear, high and changing temperatures and chemical attack.

    A wide range of pumps and rotating machines are used in this industry. Digesters, mixers, agitators, pulp pumps, screw conveyors, steam boilers – all of this equipment requires high-performance pump packing or shaft seals for efficient operation. Failures of individual pumps and machines can affect the entire process chain and can be very expensive if not addressed in a timely manner. 

    The use of innovative sealing technologies can increase the service life of the equipment and significantly reduce maintenance costs. Flushing water consumption is also considerably reduced, which is also a major benefit for the environment.

    Chesterton offers High-Performance Packing for Demanding Applications

    Reduced leakage, reduced maintenance, longer machine life – you can achieve these benefits by choosing the right mechanical packing.

    Our extensive portfolio includes high quality packing solutions that can provide excellent sealing performance, reduce operating costs and increase the productivity of your equipment by reducing downtime. We would like to highlight some special products for the complex paper industry:

    Chesterton® 377 CarbMax™ packing is successfully used for very demanding rotating machines, such as digester applications in the PPI sector. Braided to a high density, the product offers high resistance to abrasive materials and chemicals. The Chesterton 377 CarbMax™ packing is characterized by good thermal conductivity; dissipating frictional heat from the dynamic sealing surface. This robust design ensures a long service life of the packing with low maintenance requirements.  This shaft seal can improve the overall efficiency of your system by significantly extending the Mean Time between Repairs (MTBR).

    Chesterton Mechanical Packing 377 CarbMax
    Chesterton 2212 DualPac - mechanical packing

    The Chesterton DualPac® 2212 packing is a temperature-resistant, non-staining, high-pressure packing with superior sealing performance that requires minimal gland adjustment.

    Thanks to the patented braiding process, the DualPac 2212 packing combines burn- and glazing resistant materials on the shaft side with high-strength fibers on the outside.

    The high strength aramid fibers on the outside give the packing a strong, extrusion resistant and resilient base. The dynamic shaft side of the packing remains firmly pressed against the shaft and helps to ensure that the stuffing box requires only minimal adjustment, that leakage is reduced, and that the shaft is not damaged by burning and scoring.

    Many fluid media contain particles – such as the paper pulp in the pulp and paper industry. The problem with solids is that they cause excessive wear of the shaft sleeves and reduce the life of the packing. The solids usually settle at the interface between the rotating shaft sleeve and the pressure packing as they pass through the stuffing box. This reduces the Mean Time Between Repairs (MTBR) and increases maintenance costs.

    In addition to our high quality stuffing box packings, we recommend SpiralTracTM technology* to remove solids from the sealing environment to prevent wear of the shaft sleeve.

    Advantages of the additional use of the SpiralTracTM packing device

    • Reduction in pump and rotating machine downtime
    • Extension of the service life of pumps and rotating machines
    • Increased service life of the stuffing box packings used
    • Extension of the MTBR
    • Reduction in the amount of flush water required (often by 60% or more)
    Spiral Trac and Mechanical Packing from Chesterton

    When stuffing box gland bolts are difficult to access, manually adjusting the packing can be difficult and put the safety of personnel at risk.

    Chesterton AMPS (Automated Mechanical Packing System)

    This is where our Chesterton AMPS™ (Automated Mechanical Packing System) innovation is the solution. By automatically adjusting packing compression, this technology significantly reduces maintenance costs and eliminates any safety concerns. The AMPS unit maintains a constant force to the packing at all times. This process, called Active Loading, provides an even and consistent load that eliminates the need for manual packing adjustments and maximizes packing performance and life. This technology helps to minimize leakage, reduce maintenance and improve sealing performance. It also increases operator safety by allowing remote adjustment of the stuffing box pressure.

  • Chesterton® High-Performance Industrial Coating Solutions for Corrosion and Abrasion Challenges in the Pulp and Paper Industry

    Chesterton® High-Performance Industrial Coating Solutions for Corrosion and Abrasion Challenges in the Pulp and Paper Industry

    The pulp and paper sector is a demanding industry. From debarking and wood processing to the chemical processing of paper pulp and the manufacture of finished products – the work steps in this field are complex. The production of paper, cardboard and pulp requires many machines, a lot of water and certain chemicals. Plant operators have major challenges with corrosion and abrasion, which can affect the plants’ operation and performance. Increasing equipment performance, occupational and environmental safety and energy saving are extremely important for manufacturers to be able to reduce costs and increase profitability.

    How can Chesterton help to improve efficiency in pulp and paper production with high-performance industrial coatings?

    The processes used in the production of pulp and paper from wood chips, recycled paper and fibers are associated with high temperatures, high pressures, wear, abrasion, impacts or corrosion, all of which can affect the operation of mechanical equipment in various parts of the plant. High costs are incurred due to the wear of metal and concrete surfaces, erosion or cavitation of pumps, or corrosion caused by contact with chemicals. With Chesterton coatings, not only can new equipment be protected to increase the meantime between repair or failure, but also the repair and reconstruction of already damaged components is possible to increase operating lifetime, reduce spare part inventories and can therefore be extremely cost-efficient.

    wood storage for paper industry

    As in any other industry, the pulp and paper sector has several main targets:

    • Increasing profitability and reliability
      Chesterton offers a comprehensive portfolio of ARC and Ceramic-Polymer Coatings specifically designed for areas where severe abrasion resistance, long-term corrosion protection even in wet chemical applications or high temperature corrosion resistance are required. Whether concrete or steel substrates, the use of Chesterton coatings – also for surface repairs – can help extendthe service life of mechanical equipment.
    • Worker safety and environmental protection
      The long-term performance of Chesterton industrial coatings significantly reduces the need for repair and maintenance work. This not only saves labor costs, but also increases the safety of personnel. The environment benefits, for example, from properly coated secondary containment basins that prevent chemical-containing production water from entering the surrounding area. Repair and protection of operating equipment with Chesterton coatings also contributes to improved environmental performance by reducing the number of new parts that must be kept in inventory.
    • Energy saving
      The application of smooth high performance ceramic coatings to fluid flow equipment such as agitator propellers, cyclones, pipes, and many types of pumps can increase the flow speed of the fluids being handled, reduce power consumption, increase machine efficiency, and thus contribute to energy savings.

    Benefit from our experience in the pulp and paper industry

    Debarking Drums, Log Conveyors and Chippers, Agitators, Cyclones, Fan and Vacuum Pumps, Screws, Pulp Tanks, Press Rolls as well as Wastewater Tanks and Barrier Tanks – all these types of equipment can benefit from increased abrasion and corrosion protection. Chesterton industrial coatings of the ARC and Ceramic-Polymer product lines contribute to a considerably increased service life of the machines and the profitability of the entire plant is significantly improved. Furthermore, unscheduled machine downtimes due to unexpected failure or damage can be effectively prevented.

    • Cold curing Technology
      No hot work or welding is required.

    From wood to paper – requirements for coatings to protect the mechanical equipment

    First, the bark is removed from the logs, and they are processed into wood chips. Debarking Drums and Screws Conveyors or Chutes require coatings that are highly resistant to impact and abrasion. 
    Our ARC I BX1(E), for example, is designed precisely for such demanding operating conditions. High impact resistance, hardness, and resistance to sliding wear characterize this product, hence it is also used in the mining sector.

    The ARC BX2(E) is equipped with finer particles and is applied for areas in pulp processing, such as screw presses and agitators, which require moderate abrasion resistance but increased temperature resistance and chemical resistance.

    The thick film coating ARC 858(E) is ideally suited for rebuilding heavily corroded or eroded metal surfaces in pumps or pulp tanks. ARC 855(E) and ARC SD4i(E) are often used as a topcoat for these repaired surfaces. With a thin layer, this system protects metal substrates against abrasion, erosion corrosion and chemical attack.

    Of course, the Chesterton portfolio also includes coatings for the protection of concrete structures, such as wastewater basins, stock, pulp and whitewater chests or secondary containment areas with chemical tanks.

  • Chesterton® Polymer Seals for Increasing the Efficiency of Paper Machines – the Performance Lies in the Detail

    Chesterton® Polymer Seals for Increasing the Efficiency of Paper Machines – the Performance Lies in the Detail

    The pulp and paper industry uses complex paper machines that run 24/7. As in every industry, efficiency is also the key word for this sector. The goal is to achieve a high level of reliability for machine components and significantly reduce downtime for equipment repairs. With the suitable polymer seals for the various machine components, Chesterton can help to effectively extend the operational reliability and MTBF (Mean Time Before Failure).

    Paper machines consist of a variety of equipment, ranging from rotating equipment of all kinds to hydraulic and pneumatic cylinders, hydraulic directional valves, control automation, but also various types of fittings such as valve flanges and dispensing systems. Chesterton offers specific polymer seals made from high-performance materials for these different devices.

    Chesterton EPS for pulp and paper machine
    Agitator for Pulp and Paper Mill

    Rotating equipment in the paper industry: What are the challenges and how can we counteract them?

    In rotating machinery such as pumps, agitators, hydropulpers, gearboxes, fans, bearing housings, electric motors, and roll pivots, bearing failure is the main challenge. In the tough world of the pulp and paper industry, bearings are exposed to a variety of contamination including water, dust, heavy loads, vibration, abrasive contaminants and corrosive vapors. This leads to unreliability and very often to a significantly shorter bearing life.

    Bearings usually have lip seals (usually made of some kind of elastomer such as rubber) as a first line of defense. However, these only protect the bearing for a short time, far below the actual bearing service life. The rubber lip seal is there for keeping lubricant such as oil or grease inside the bearing not as protection function and was not designed for it even in many cases.

    If these conventional lip seals fail, liquid from the environment penetrates into the bearing housing. This washes away the second line of defense – the grease – and exposes the bearing metal to the extremely corrosive atmosphere. Heat, chemical load and the humid ambient conditions lead to bearing corrosion. Due to corrosion, bearings fail after a few thousand operating hours and, in the worst case, to the failure of the entire machinery. The solution to premature bearing failure is, of course, a high-quality grease for smooth bearing movement and a functioning lip seal. This can significantly extend the MTBF (Mean Time Before Failure) and the bearing service life.

    The first line of defense for equipment storage – Chesterton® Rotary Seals

    Chesterton has an extensive portfolio of excellent rotary seals, in particular the 30K Bearing and Gearbox Protection Seal, which is often chosen in the paper industry for its outstanding protective properties and durability.

    Furthermore, the split polymer seals are explicitly suitable for rotating equipment in the paper industry, offering high performance and quick and easy installation. For example, Chesterton’s patented  Matrix Rotary Seal is a split bearing protection seal developed to work on worn shafts and applications with high shaft runout.

    The non-contact Split Polymer Labyrinth Seal (SPLS) is specially developed for splash water lubricated bearing protection in large pumps, gearboxes and other rotating equipment. Here, the specific design helps to ensure effective protection: during operation, centrifugal forces and gravity ensure that the lubricant remains in the labyrinth and flows back into the bearing housing, while contamination from outside is excluded and directed back into the atmosphere.

    The R22KN5 Split Rotary Seal is used for slow-rotating applications. There are high-performance polymer materials, such as AWC860 Cherry Polymer, which are one of the best sealing solutions for pulp washer screens and filters in cellulose production.

    Product advantages and product benefits of Chesterton polymer seals for the protection of machine bearings

    • Low shaft friction
    • Sealing against external contamination of the bearing
    • Maintaining bearing lubrication
    • Long service life
    • High-performance construction and material
    • Simple installation (with split seals)
    • Extending the MTBF of rotating equipment

    Cylinder optimization with the 1-2-3 System from Chesterton – extending the service life of hydraulic cylinders

    In the pulp and paper industry, there are numerous hydraulic devices such as cylinders, presses, lifters, valve drives, pumps, control valves and directional valves. If cylinder seals do not perform adequately, leaks occur and hydraulic fluids spill out. These leakages cause contamination of the product, which leads to production losses, and have a negative impact on the environment and occupational safety.

    Chesterton EPS for pulp and paper machine

    Defective seals also provide no protection against external influences and contamination. Dirt particles enter the cylinder, causing corrosion and failure of the hydraulic system.

    Product-specific designs and complete sealing kits for cylinder applications optimize the performance of your systems. Complex packages for engineering advice, on-site support, failure analysis and retrofit components are also included in the comprehensive Chesterton service.

    The use of our high-performance cylinder seals in application-specific materials can

    • Minimize downtimes and maintenance costs
    • Improve reliability of the hydraulic system
    • Help extend the service life of hydraulic cylinders
    • Reduce the consumption of hydraulic fluid, avoid leakages

    Proactive maintenance for cost savings

    In paper and pulp production, we can help our customers in many ways. In numerous reference cases, the Chesterton ConnectTM System provides support by monitoring the stuffing box pressure, the process temperature, the vibrations and the surface temperature.

    Typical applications

    One critical application in the process is the monitoring of the flow of stock supplied to the paper machine by the fan pumps. In this application, this is critical as the suction pressure and flow to the pump must be uniform and uninterrupted. Anomalies in the fan pumps can be localized and proactively eliminated before the reliability of the system is compromised or there is a risk of serious damage to the pumps.

    Another application is to monitor equipment after it has been installed. It is very common for a poorly fitted mechanical seal, a shaft misalignment problem or a faulty valve to cause failure very quickly. In this case, continuous monitoring of the equipment allows the user to be informed quickly in the event of a malfunction. Without an IIoT monitoring system, it is usually very difficult and time-consuming to find the real error in the system.
