We understand the need for high-quality seal support systems to maximize rotating equipment uptime in petrochemical operations. When faced with seal flush challenges, you need a mechanical seal support plan or kit assembled, tested, and delivered ASAP.

Your mechanical seal support plan or kit should not only lubricate and flush seal faces while controlling pressure and temperature in seal chambers—they should also:

Promote safe operations by design
Be optimized for operator access and maintenance
Be configured for your specific application and process conditions
Incorporate high-quality components to prevent costly leaks
Be designed for ease of installation

When rotating equipment fails, it’s often due to a seal failure. In fact, about 40% of all unscheduled critical pump shutdowns are caused by mechanical seal failures (Grundfos). And shutdowns are often expensive.

"The diagrams... show that shaft seal failure is by far the most common cause of pump system failure. See figures 5.1 and 5.2," writes Grundfos.

Swagelok’s seal plans maximize the life of mechanical seals and the reliability of rotating equipment by maintaining lubrication and pressure with properly conditioned fluid flows.

Designed for reliability and maintenance

Proper start-up and commissioning are critical for reliable operation of mechanical seals and their associated support systems. For example, air in the system at startup can lead to issues with the seal support system. Flow can be disrupted or stopped in systems with chillers or seal pots. Air inclusions can also prevent the support system from providing the desired rate of cooling. Swagelok design options include high-point vents in the seal support system, so the system can be cleared.

Designed for system safety

API 682 recommends specific wall thicknesses for 1/2 inch (12 mm) to 1 inch (25 mm) OD tubing. While thinner-walled tubing, such as that used in general instrumentation installations, is often sufficient to handle the pressure and temperature of seal support systems, heavier-wall tubing provides extra rigidity in high-vibration service. Tubing with a heavier wall also creates systems that are more robust in areas where large pieces of equipment are being maintained and personnel may inadvertently come into contact with the tubing.

Designed for appropriate flow

A common flow issue is clogged orifices, which can cause a loss of flush fluid to the seal chamber, resulting in seal failure. Additionally, improper circulation of buffer and barrier fluids can also cause operational issues due to lack of appropriate system cooling. Swagelok systems are designed to prevent such this and other causes of inappropriate flow.

Designed for tailoring to individual needs

Swagelok's API 682 standard designs incorporate all the recommended components and adhere to best practices. For better operation and service of the seal and pump, we go beyond the standards to design systems specific to your application. This includes optional isolation valves, bypass loops, and instrumentation to assist the pump operator in both maintaining the system and monitoring the health of the seal.

About our kits

Seal plan kits (SPK) are a collection of components that are used to connect the seal support plan to the pump. Each kit contains everything needed for proper installation, including an engineered drawing. For projects or turnarounds, seal plan kits can be used to standardize how plans are connected to the pump. Kits also adhere to API best practices by showing technicians where to bend tubing to eliminate potential leak points through the reduction of elbow fittings and pipe threads.

About our assemblies

Seal plan assemblies (SPA) are panels, seal pots, or skid systems that comprise the majority of the API seal support plans. The seal plan assembly ordering numbering structure allows users to select a variety of configurations and additional system components to meet specific site or application requirements. Options and configurations not listed in the ordering numbering structure are also available. Seal plan assemblies can be ordered alone or with the associated field installation kit to provide a standard installation for site personnel.

This includes optional isolation valves, bypass loops, and instrumentation to assist the pump operator in both maintaining the system and monitoring the health of the seal.

Additional options

And with Swagelok Custom Solutions from Edmonton Valve we can also:

"Standardization was a key driver to improve ease-of-use, consistency, and safety when dealing with multiple sites. Offering custom L porting tandem bypass valves to eliminate operator error and bleed off valves so operators can simulate a seal leak to test high flow alarms were just some of the improvements Swagelok helped deliver." —Mechanical Design Engineer, Chem/Petro (Canada)

"Swagelok was instrumental in providing critical support during an unplanned outage. With Swagelok’s support, we were able to have a seamless and on-time startup of a critical unit. Swagelok worked diligently to design standards, improve lead times, and deliver panels by our very aggressive need-by date."—Reliability & Rotating Equipment Engineer, Chem/Refining (US)

"The new lube systems are compact, operator friendly, and equipped with modern filtration and coolers that are readily available. In addition, they are neat, clean, and leak-free. The cleanliness and temperature of the delivered oil is markedly improved. The installation will no doubt improve the reliability and maintainability of these gearboxes going forward." —Machine Shop Operator, Chem/Refining (US)

“Our refinery is now benefiting from improved seal flushes to the seals and can easily see if there is an issue. The shaft seal leaks no longer dictate our refinery’s maintenance interval and we consider the Swagelok Plan 32 panel a reliable system.” —Reliability Manager, Refinery (US)

"Swagelok’s customized extended male connector fitting has allowed the simplification of these installations. This arrangement not only looks cleaner, it eliminates several pipe joints that no longer need to be monitored for potential leaks." —Rotating Equipment Reliability Manager, Chem/Refining (US)
