Cartridges Sealed
Cartridge Mechanical Seals Performance Range Standard
Mechanical seal must live in literally every environment under the sun-from extreme hot to extreme cold, wet to dry, solid to gas, acidic to caustic and so on. Until relatively recently, a vast variety of mechanical seals were needed to accommodate these pump applications.
Cartridge Seals
The advent of standard cartridge designs allowed for easy, trouble-free installation on equipment, but they were limited as to the variety of applications each design could handle. With the introduction of universal or modular cartridge seals, one seal family utilizing various combinations of common cartridge seal hardware and seal faces can be applied virtually throughout a plant, increasing seal life. It reduces complexity while conserving valuable resources time and money.
The implications of this technology are far-reaching. Plant-wide seal standardization streamlines operations. The number of variables in installation and maintenance is reduced, and the process is simplified. This increased operational efficiency reduces maintenance costs. Streamlining the process also ensures that the seals are installed correctly, and correctly installed seals increase plant reliability. Using a standard seal family can also reduce a plant's spare parts inventory and material costs.
Modularity
Universal/modular cartridges are based on a modular concept that allows application-specific seal arrangements that incorporate interchangeable seal face material, elastomer bellows, O-ring or metal bellows seal heads fitted to standard adaptive hardware (typically the gland plate, sleeve, collar and setting tools). Universal or modular seals typically fit both standard ANSI B73.1M and DIN 24960 pumps, so users who are already comfortable with a particular seal type and have both ANSI and DIN pumps benefit from the technology. The flexibility from modularity also enables the universal cartridges to meet a wide range of service requirements.
Modularity allows the building of seals appropriate for a given application. By standardizing the adaptive hardware into which the appropriate seal is applied, the seal technology can change to fit the individual pump's environment. Handling temperatures to 400-deg F, pressures to 400-psig and speeds to 5,000-rpm, these seals accommodate fluids such as aqueous solutions, caustics, hydrocarbons, acids and even dry running.
Configurations
Basic configurations can cover an extensive range of applications. The unique design of universal/modular cartridge seals increases component interchangeability across a variety of configurations. Single and dual arrangements typically incorporate the same seal head for both the inboard and outboard seal, which applies to both O-ring and metal bellows designs. In fact, the O-ring seal heads can be directly interchangeable with the metal bellows seal heads.
This flexibility offers some important advantages. On site, a technician can easily upgrade or change the capabilities of the seal in minutes without discarding the existing seal. Within a common set of adaptive hardware, an O-ring seal can be transformed into a metal bellows seal, and a metal bellows can become an O-ring seal. With other combination of parts, either can change into an elastomer bellows design. Upgrading or changing the seal with interchangeable components conserves resources since no components are wasted.
The heads and mating rings are also interchangeable in some designs. This flexibility gives the user the option to select whether the seal head or seat should rotate according to specific needs or preference. Operating with the inboard seal head rotating helps remove any solids build-up that creates, in essence, a self-cleaning rotational action.
On the other hand, a rotating mating ring and stationary seal head accepts more gland or shaft misalignment, which allows higher shaft speeds and provides greater cooling efficiency. Single seal versions can typically accept a quench gland with a restriction bushing or lip seal, and dual seals can use pumping rings to assist barrier fluid circulation. This flexibility also makes universal/modular seals both ANSI and DIN pump compliant. The seal's gland is designed with slots to accommodate multiple bolts and bolt circle diameters. Pipe taps are freely accessible to allow universal fitting to either ANSI or DIN standard pumps rotating clockwise or counterclockwise.
Seal Design Advantages
Seal manufacturers continually enhance designs to provide maximum reliability, emission containment and cost-efficiency. Each of the basic versions-the O-ring pusher, metal bellows and elastomer bellows non-pusher-has inherent benefits.
The O-ring pusher seal, perhaps the most versatile of seal designs, accommodates a wide range of elastomer materials and handles the most difficult chemical service conditions.
The elastomer bellows seal is an excellent general purpose application seal, providing flexibility and hang up resistance as well as self-alignment, which is an important maintenance-saving feature. Automatic adjustment compensates for potential problems commonly found on older equipment such as abnormal shaft end play and runout.
Advantages of the metal bellows seal include self-cleaning and increased reverse pressure capability. The reverse pressure capability feature found on most modern modular seal designs allows the use of the same dual seal for pressurized barrier or unpressurized buffer fluid applications, and will handle system upsets
Efficiency and Flexibility
The advanced technologies incorporated in today's universal/modular seals increase efficient seal operation and reduce overall costs. This is even more evident in the advanced capabilities now available, such as wet and/or dry running seals. This advanced technology is perfect for applications that may run dry on occasion, such as tank car loading or unloading, or even full-time dry running for single seals and secondary containment on dual seals.
Narrow-faced seals with rugged drive mechanisms and interchangeable hard (tungsten or silicon carbide) seal face material allow seals to perform longer in higher viscosity fluids and/or applications with a high number of starts and stops.
Non-contacting spiral groove upstream pumping technology eliminates or significantly reduces the costs of complex, high pressure buffer fluid systems needed in dual mechanical seal systems. This technology reduces seal face heat, seal support systems cost and has proven to reduce operating and maintenance costs.
