Mechanical seals are made using both flexible and rigid elements. The combination of materials maintains contact to create a seal at their interface, while allowing the rotating shaft to pass through. A spring or other device is both hydraulically and mechanically loaded to maintain the seal.

1400 series are glass filled PTFE piston seals with a rubber energizer. Designed for low friction and high strength in a double-acting seal. It can withstand a temperature range of -40 to +220 F, a presure range of 0 to 5,000 psi, with a speed of 12 ft/second.

Magnetic seals are used when axial space is limited to <.500" and operating conditions and customer requirements are beyond elastomeric or polymer seal capabilities. Our magnetic seals have two components: the seal head assembly and the magnetic mating ring. These two components create a magnetic attraction, which eliminates the need for a spring and other items needed in face seal designs. This allows for our seals to be used in a variety of applications that have limited space requirements.

For rotating shaft equipment and machinery that include large pumps, seal maintenance can be a time-consuming and expensive proposition. That was the case at one Midwestern power plant, where installing and maintaining the cartridge seals on its six large, recirculating service pumps were a regular ordeal.

Repairing or replacing one of its cartridge seals was a process that involved disassembling the pump, removing and replacing the seal and rebuilding the pump—which required 240 man-hours throughout multiple days. The plant usually performed seal maintenance at least once per year on these large pumps, so the labor hours and costs added up quickly.

Each time the plant performed its cartridge seal maintenance, it relied on a backup pump while the regular pump and its associated system were down. The plant provides essential electricity to the surrounding area, including fire stations, hospitals, retirement communities and the general economy as a whole. If the backup pump experienced any problems, the results could be catastrophic.

The power plant’s seal maintenance issues are familiar to maintenance personnel and operators in many other process industries. Long periods of downtime for maintenance can eat into production time and profits.

According to U.S. Department of Labor statistics from December 2011, the utility industry pays $57 per hour on average to its workers, including wages and benefits. Based on that figure, the power plant spent more than $13,000 in labor costs alone to maintain one seal. That figure also does not take into account the cost of the new seal and any related pump parts or materials that were needed.

While some industries shut down production to replace a seal on a pump, shutting down is not an option for power plants or other essential service providers. These providers often rely on backup equipment during maintenance, making quick up-time for their regular equipment particularly critical. A problem with a backup pump can result in the loss of key services, fines from governmental agencies and millions in lost revenue.

Anxious to reduce its maintenance time and costs, the power plant operators decided to replace the cartridge seal on one of its large pumps with a fully-split mechanical seal. Unlike conventional non-split, cartridge seals, split seals can be installed without dismantling the equipment that they are sealing. This makes them a good choice for hard-to-disassemble equipment, time-sensitive services or critical systems.

When selecting a split design seal, operators must follow the same selection criteria as for a non-split design, paying close attention to all operating conditions. As with non-split mechanical seals, a variety of designs are available to meet the needs of a number of particular applications. In this particular situation, the plant chose a split seal that was designed specifically for heavy-duty horizontal or vertical rotating shaft equipment and pumps that are challenging to maintain.

The seal could handle large shaft deflections, high vibration levels and even major misalignment. The selected design also featured a minimal number of components and no springs or O-rings, which streamlined the installation process further and helped prevent installation errors.

The plant’s maintenance personnel spent between eight and 10 man-hours on the initial installation of the split seal on the 10-foot-high pump, which was nearly 25 times fewer man-hours than the previous cartridge seal’s maintenance turnaround. The split seal installation involved the one-time removal of the original, non-split cartridge seal; installing a special hardware adapter to which the split seal mounts; and mounting the seal outside the pump’s sealing chamber. This installation location allowed for the easy access and visibility of all the split seal parts. Upon completion, any future seal maintenance required just one to two man-hours each time to inspect or replace any necessary components.

While split seals require less installation and maintenance time than non-split cartridge seals, the two types are virtually identical in performance. Split seals can withstand similar pressures, temperatures and shaft speeds as non-split seals and operate just as well.

The power plant installed its split seal on a pump recirculating limestone slurry, but split seals also perform well in other challenging sealing services. Based on their needs, operators in a wide variety of process industries can choose from split seals designed to handle wet-running services, such as:

After a few weeks of problem-free operation, the power plant was sold on the split seal’s performance. The plant is now researching the conversion to cartridge seals on its other pumps to split seals.

In many cases, Cartridge Seals may contain the exact same major items that are sold separately as Component Seals. These pieces include the Rotary Seal and Stationary Face as well as other minor parts like O-rings or Gaskets all required at assembly. The advantage of using a Cartridge Seal is that the time required for installation, and even more importantly, the possibility of error during installation is dramatically reduced. When installing a Cartridge Seal, the necessity of having to measure internal components positioning on the shaft to achieve proper face loading is eliminated. Cartridge Seals come pre-assembled from the factory with all internal components assembled with proper face loading and all pieces in place, exactly where they should be. Cartridge Seals eliminate the need to handle delicate, polished parts such as Seal Faces that can be compromised by the presence of dirt, smudges and oils that can result from handling during assembly. So, for the easiest and most reliable Seal installation, Cartridge Seals go a long way towards helping you achieve trouble free startup and extended service life from your equipment.

Structural Features: single end, unbalanced, dependent direction of rotation, rubber bellow, bellow transmission. This component has a compact structure with good compatibility and easy installation. The bellow can provide support against the pressure to eliminate indentation and corrugation. The bellow and the spring provide pressure compensation to the seal faces. The rubber bellow design prevents possible radial run-out so that the floatability of the rotary ring is increased.

This mechanical seal is also known as KSB Part No. 433 mechanical seal. Many other pump manufacturers such as WILO are also using the same type of mechanical seal as their standard sealing solutions.
