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.

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.

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 the fourth edition of the API 682: Pumps - Shaft Sealing Systems for Centrifugal and Rotary Pumps.

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.
