7 Static Testing
The ISC2 dual rotating bellows seal may be static tested at pressures up to 300
psi [20.6 bar] prior to installation on the equipment. Flowserve manufacturing
typically tests the ISC2 at 25 psig [1.7 bar]. 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 setting devices due to
axial loads. The seal can be pressurized through the tangential flush port. If the
seal does not pass, according to QP-B.28, the static pressure test, disassemble
the seal and inspect for O-ring damage, as this is the most common cause of
static test failure.
