Maintenance (Continued)333AINPRO labyrinth oil seal descriptionDescriptionThe INPRO VBXX-D Labyrinth Oil Seal consists of the rotor (1), the stator (2), and the VBX Ring (3).The rotor (1) fits over the shaft and is held in place by an elastomeric drive ring (4). The drive ring causesthe rotor to turn with the shaft and provides a positive, static seal against the shaft. Since there is no metalto-metalcontact, there are no friction or wear concerns.NOTICE: The INPRO VBX is a one-piece design. Do not attempt to separate the rotor from the statorbefore or during installation. Doing so may result in equipment damage.BACA"VBX" O-ring actionBStaticCDynamic1 Rotor2 Stator3 "VBX" ring4 Rotor drive ring5 Stator gasket6 Expulsion port7 D groove8 Lube return9 Location shoulderAssemble the INPRO labyrinth oil seal1. Wrap electrical tape around the coupling end of the shaft to cover the keyway.100 Model 3796 i-FRAME Installation, Operation, and Maintenance Manual
Maintenance (Continued)NOTICE: The edges of the keyway can be sharp. Make sure to cover the keyway with tape. Failure todo 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-ringmaterial and the pump-system standards.3. Use an arbor press to install the outboard INPRO VBXX-D into the bearing cover with the expulsionport (6) at the 6 o'clock position.Press the outboard INPRO VBXX-D down to where the stator location ramp (9) starts to avoidangular 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 modelSTiActionPress 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 overthe shaft and into the adapter.Assemble the C-face adapter1. 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 fourbolts.3. Mount the motor to the C-face adapter using either four or eight motor bolts.Shaft sealingThis table contains the motor-bolt torque values for assembling the C-face adapter to a frame.Table 15: Motor-bolt torque values for C-face adapter to frameFrame Lubricated threads Dry threadsSTi 20 ft-lb (27 Nm) 30 ft-lb (41 Nm)MTi 20 ft-lb (27 Nm) 30 ft-lb (41 Nm)LTi 20 ft-lb (27 Nm) 30 ft-lb (41 Nm)This table contains the motor-bolt torque values for assembling the C-face adapter to a motor.Table 16: Motor-bolt torque values for C-face adapter to motorFrame Lubricated threads Dry threads143TC-145TC 8 ft-lb (11 Nm) 12 ft-lb (16 Nm)182TC-286TC 20 ft-lb (27 Nm) 30 ft-lb (41 Nm)324TC-365TC 39 ft-lb (53 Nm) 59 ft-lb (80 Nm)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.Methods for sealing the shaftThese sections discuss the methods that you can use to seal the shaft.• Seal the shaft with a dynamic seal.• Seal the shaft with a cartridge-mechanical seal.• Seal the shaft with a conventional inside-component mechanical seal.• Seal the shaft with a conventional outside-component mechanical seal.• Seal the shaft with a packed stuffing box.Model 3796 i-FRAME Installation, Operation, and Maintenance Manual 101
