5 Static Testing

5.1 Flowserve manufacturing typically air tests the ISC at 25 psig. A pressure drop

of less than one pound at 25 psig is acceptable. To static test the seal, bolt

it to a single seal test barrel or to the equipment. Secure the cup point set

screws to the stub shaft or equipment shaft to help prevent deformation of

the centering tabs due to axial loads. The seal may be pressurized through

either of the tangential flush ports, identified with the letter "F" cast into the

gland. If the seal does not pass the static pressure test, disassemble the

seal and inspect for O-ring damage, as this is the most common cause of

static test failure.

6 Installation

6.1 Refer to the ISC Installation Instructions, FIS120, for proper seal installation.
