RKCS VERSION C SINGLE CARTRIDGE SEAL - QUENCH SEAL SUPPORT SYSTEM INSTALLATION

The following steps briefly describe the methods in which a quench system should be set up to support the

RKCS Version C with an outboard lip-seal and fluid guide sleeve.

. For quench operation, connect a suitable liquid quench supply to the quench port.

• For typical applications, Flexaseal recommends throttling the liquid quench to 1/4 gallon per minute.

Consult Flexaseal for specific applications and details.

Use thread sealant instead of thread tape. Thread tape has been known to break apart and

enter the quench fluid stream, resulting in damage to and premature failure of the

mechanical seal.

Ensure that all tubing/piping is free of pipe strain, which can adversely affect the seal.
