ITT 3196 i-FRAME - Assemble the C-Face Adapter; Shaft Sealing

NOTICE: The edges of the keyway can be sharp. Make sure to cover the keyway with tape. Failure to
do so may result in cutting the O-ring and damaging the seal.
2. Lightly lube the shaft and the drive ring (4) with lubricant.
Lubricant helps in the installation process. Be sure that the lubricant is compatible with the O-ring
material and the pump-system standards.
3. Use an arbor press to install the outboard INPRO VBXX-D into the bearing cover with the expulsion
port (6) at the 6 o'clock position.
Press the outboard INPRO VBXX-D down to where the stator location ramp (9) starts to avoid
angular misalignment. There is a nominal 0.002 in. (0.051 mm) interference fit.
4. Discard any residual material from the stator gasket (5).
5. Complete the applicable step in this table depending on the model of your pump.
Pump model Action
STi Press the inboard seal along the shaft into the bearing frame.
All other models After you install the frame adapter on the bearing frame, press the inboard seal over
the shaft and into the adapter.
Assemble the C-face adapter
1. Mount the pump and the motor-coupling hubs if they are not already mounted.
2. Slide the C-face adapter over the pump shaft and mount it against the bearing-frame flange using four
bolts.
3. Mount the motor to the C-face adapter using either four or eight motor bolts.
This table contains the motor-bolt torque values for assembling the C-face adapter to a frame.

Shaft sealing
WARNING:
The mechanical seal used in an Ex-classified environment must be properly certified. Prior to startup,
make sure that all areas that could leak pumped fluid to the work environment are closed.
NOTICE:
The mechanical seal must have an appropriate seal-flush system. Otherwise, excess heat generation and
seal failure can occur.
