Adaptor for Seals

The split device made of ESC material has been pressure tested to 100 PSI / 6.9 Bar. The typical applications for the Adaptor are well within this limit. Should you have a higher-pressure application and still require a split device, contact EnviroSeal.

The two halves are machined to a smooth finish to ensure total face contact when tightened together with the socket-head cap screws that are supplied with each device. Split metal Adaptors are supplied with a gasket sealant which should be applied for each half.  Refer to installation instruction for details.

No, these SpiralTracs are not designed to work with packing.

The turbulence in the seal cavity will not be changed with the standard Adaptor. What is important is to protect the environment around the seal itself, and that is achieved with this design. An option, should you wish to control the turbulence in the seal cavity, is to order the Adaptor with a nose piece that will fill the entire void of the seal cavity. It is important to note that this option can be used only when there is enough first obstruction space available.

Typically, hard face seal combinations are used when erosive solids are present in the seal cavity.  With SpiralTrac, however, solids are no longer present in the cavity.  Since the seal is now operating in a cleaner environment, soft face seal combinations can be used at substantially reduced costs.  Soft face seal combinations will also run cooler, further extending the mechanical seal’s life.  Contact your seal manufacturer for recommendation. 

No. We recommend to use flush with all SpiralTrac Adaptors.

SpiralTrac Adaptor can be your answer when:

• Box bore too big/small (for gasket of seal)
• Bolt pattern too big/small (for seal mounting)
• Shaft wear (moving seal closer to clean part of shaft, closer to bearings)

Split SpiralTrac Adaptors are available in ESC and metal.

Composite Adaptors have a built-in gasket. For metal Adaptors customer must supply their own gasketing material.
