5 Static Testing
5.1 The ISC single elastomer bellows seal may be static tested at pressures up
to 150 psi prior to installation on the equipment. Flowserve manufacturing
typically tests the ISC at 25 psig. 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 prevent deformation of the centering tabs
due to axial loads. The seal may be pressureized through either of the
tangential flush ports. 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.
