Mechanical Seal Support Assemblies

Swagelok has developed kits and assemblies that help customers protect mechanical seals in rotating equipment by maintaining lubrication and pressure with properly conditioned fluid flows. Collaborate with us to ensure the best match between current needs and Swagelok solution, ensure appropriate flow is maintained, and ensure the proper amount of tubing and tube support materials are on hand.

Improving mechanical seal reliability

Swagelok Seal Support Systems supply either a gas or a liquid to a mechanical seal to regulate the environment in which the seal operates, protecting rotating equipment from damage. These systems provide lubrication to seal faces, control pressure and temperature in the seal chamber and seal, flush the seal of contamination and/or residue build up, and prevent system process fluid from leaking to atmosphere.

Seal Plan Kits

Seal plan kits (SPK) are a collection of components that are used to connect the seal support plan to the pump. Some API plans are offered only as a kit ready for field installation. Kits include all components needed to complete the plan, eg process side plans 11, 12, 13, 14, 21, 22, 23, 31, 41; and atmospheric side plans 51, 62, 65A, and 65B.

Seal Plan Assemblies

Seal plan assemblies (SPA) are panels, seal pots, or skid systems that comprise the majority of each API seal support plan. Ordering numbering structure allows for users to select a variety of configurations and additional system components to meet requirements. Options and configurations not listed in the ordering numbering structure are also available.

Benefits of collaborating on seal support

Ensuring appropriate flow is critical. For example, it is important to have pressure drop and flow control happen at appropriately engineered locations, such as orifices and flow control valves. Maintaining proper flow and circulation through the support system and seal chamber is key to effective operation. The design of tubing is also key.

There are safety issues to consider as well. For example, when choosing the appropriate design for an API plan, it may be necessary to incorporate  block-and-bleed valves on all instruments, including gauges. Last but not least, not all options are listed in Swagelok literature. The addition of isolation valves, bypass loops, and instrumentation are available to assist the pump operator in maintaining the system and monitoring the health of the seal.

With the above issues in mind, let's compare having Swagelok help to handling it in-house:

What to expect

These are usually the main steps in producing a custom solution for mechanical seal support:

1. Design

Starting with a phone conversation, we gather information about your application, seal chamber conditions (flow, temperature, pressure, etc), location of mechanical seals, maintenance routines, tubing runs, and other data.

2. Fabrication

Certified technicians handle fabrication, working in our Class 100 clean room if necessary. Swagelok assembly certification involves producing dozens of samples, each of which is inspected by Swagelok manufacturing engineers and put through destructive testing. Passing requires a 100% score.

3. Quality Control

In addition to standard testing, we can do helium leak testing, hydrostatic testing, nitrogen pressure testing, and pressure decay testing. And every Swagelok product, assembly, and solution comes with Swagelok's warranty.

4. Delivery

We clean and either cap or bag the kit or assembly to ensure contaminants are not introduced into your fluid system from the assembly. A test certificate is packaged with each assembly. Orders ship daily or can be picked up in Concord, Sunnyvale, or Fremont.
