Mechanical Seal Support Systems
Seal Support Systems for Pumps, Agitators, and Mixers
Seal support systems are designed to support a specific mechanical seal and set of process conditions. These systems supply either gas or liquid to the mechanical seal to regulate the environment in which the seal operates.
Swagelok seal support systems are guided by API 682 and are offered as kits and assemblies
Swagelok seal support system designs avoid pipe threads and limit the number of connections wherever possible. Based on the fourth edition, the standard design for each plan includes the minimum arrangement of components as detailed in API 682: Pumps—Shaft Sealing Systems for Centrifugal and Rotary Pumps. Learn more about how our configurable, locally available, and reliable systems are better by design.
Local Support Maximizes Uptime
Swagelok Thailand is your local source for API 682 mechanical seal support plans configured for your application. To help with labor, installation, and inventory costs, seal plan kits that bundle plan components are also available.
Our certified technicians undergo a comprehensive training and recertification program every three years to ensure your system is assembled to strict guidelines, providing you with reliable, consistent mechanical seal support systems.

Our innovative use of components reduces threaded connections where costly leaks can occur. Swagelok seal support systems are available as assemblies or kits for easy assembly and reduced installation errors.
Seal Plan Kits
Seal plan kits (SPK) are a collection of components that are used to connect the seal support plan to the pump. Due to the simplicity of the arrangement, the following API plans are offered only as a kit of components that are ready for field installation. These kits include all the necessary components to complete the plan:
• Atmospheric side plans: 51, 62, 65A, and 65B
• Process side plans: 11, 12, 13, 14, 21, 22, 23, 31, and 41
Seal Support System - Atmospheric Side Plans
Swagelok-built atmospheric side plans for seal support are available as seal plan kits only. Each kit contains everything needed for proper installation, including an engineered drawing, making it simple to standardize how plans are connected to the pump during turnarounds or other projects.
Seal Support System - Process Side Plans
Most Swagelok-built process side plans for seal support are available as seal plan kits. Each kit contains everything needed for proper installation, including an engineered drawing, making it simple to standardize how plans are connected to the pump during turnarounds or other projects. These 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.
Seal Plan Assemblies
Seal plan assemblies (SPA) are panels, seal pots, or skid systems that comprise the majority of each API seal support plan. Seal plan assemblies can be ordered alone or with the associated field installation kit to provide a standard installation for site personnel. The following plans are offered fully assembled with a corresponding field installation kit also available for connecting the assembly to the pump:
• Process side plan 32
• Between seal plans 52, 53A, 53B, 53C, 54, 55, 72, 74, 75, 76, and 72/76
Seal Support System - Between Seal Plans
Swagelok-built between seal plans for seal support are available as seal plan assemblies only. Options and configurations not listed in the ordering numbering structure are also available, and seal plan assemblies can be ordered alone or with the associated field installation kit to provide a standard installation for site personnel.
