INSTALL THE GLAND
Slide the gland o-ring and gland over the shaft and position it onto the studs on the
bracket. Install the washers and nuts and tighten.
FLUSH ARRANGEMENTS (see Figure 4)
Note:
The standard bracket for the GlobalGear pumps provides a vent to the seal
chamber from suction port of the housing (see Figure 4). Position the bracket so the
vent hole lines up with the hole in the housing by the suction port.
If the viscosity of the application is greater than 7500 SSU (1650 cst), the orifice plug
should be removed.
D. Pumps with cartridge seal
Consult the separate seal instructions provided with the new seal.
Rebuild Drive Module Assembly
See Table 4 for proper torque specifications.
Place the rotor into the bracket and place this assembly on a flat surface so the shaft points
upward.
Note:
The standard bracket for the GlobalGear pumps provides a vent to the seal chamber from
suction port of the housing (see Figure 4). Position the bracket so the vent hole lines up with the
hole in the housing by the suction port.
If the viscosity of the application is greater than 7500 SSU (1650 cst), the orifice plug should be
removed.
Install the bearing carrier onto the bracket.
Place the inner bearing cap over the shaft.
Install the new ball bearing onto the shaft. The bearing may have a slight press on the shaft so
the bearing may have to be tapped on. Ensure that it bottoms out on the shaft shoulder. The
bearing must be pressed on the inner race, not the outer race. Pressing on the outer race could
damage the bearing.
!
CAUTION
Do not use excessive force when pressing the bearing onto the pump shaft, as it could damage
the mechanical seal.
Install the bearing lock washer and locknut. After the locknut is tightened, bend one of the lock
washer tabs into the locknut slot, to ensure that the locknut cannot vibrate loose.
