Mechanical Seal Support Systems
Seal Support Systems for Pumps, Agitators, and Mixers
Configurable. Local. Reliable.
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.
If the seal system fluid is dirty or contains particulate, seal life can be negatively affected. Similarly, delivering the fluid at the wrong pressure or temperature can cause premature or even catastrophic seal failure. That's why making sure your seal support system is properly designed and installed is critical to keep your rotating equipment available for production.
Swagelok seal support systems are guided by API 682 and are offered as kits and assemblies.
Guided by API 682
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.
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. 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.
Seal Plan 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.
When procuring seal plan assemblies for pump installations or retrofits, please contact your authorized Swagelok sales and service center to ensure the proper amount of tubing and tube support materials are provided for a safe and effective installation.
