Figure 13 – Grease Lubricated Thrust Pot
INSTALLING THE OIL LUBRICATED THRUST POT
If the unit is supplied with a thrust pot (see Figure 14),
the thrust pot should be installed on top of the discharge
head or motor stand before installing the driver. The
driving mechanism of the thrust pot assembly is similar to
the hollow shaft motor. (See Figure 7)
1. Attach a sling to the thrust pot assembly through
the windows on the motor adapter and hoist the
assembly over the top of the discharge head.
2. Clean the mounting face with a flat file to remove
any burr of the discharge head and the thrust pot.
Lower the thrust pot assembly and orient it so that
the bolt hole on the base of the thrust pot and the
top flange of the discharge head are lined up. Install
all the bolts to secure the assembly to the discharge
head.
3. Lower the drive shaft through the quill of the thrust
pot assembly to meet the shaft coupling. Apply a
thin film of oil to the head shaft thread and screw
into the shaft coupling.
4. For unit with mechanical seal and flanged coupling,
install the spacer flange coupling as instructed on
page 16.
5. Install the gib key (#16) into the drive shaft and the
hollow shaft clutch.
6. Install the adjusting nut (#17) to hand tight.
7. With shafting all the way down and the impellers
resting on their seats, turn the adjusting nut (#17)
in counter-clockwise direction, thus lifting the shaft,
until the impellers just clear their seats and the
shaft/motor turns free by hand. This removes all
deflection from the shaft.
8. Line-up one of the holes in the adjusting nut with
the nearest hole in the driver coupling. Insert the
capscrew in the hole and tighten it.
NOTE: 1.00” and 1.18” diameter shafts are 12 tpi, 1.50"
through 2.44" are 10 tpi, all larger sizes are 8 tpi.
9. Install the bottom of the flexible coupling to the top
of the drive shaft.
10. Attach a sling to the lifting lugs of driver and hoist
the driver up. Inspect the mounting surface, register
and clean these surfaces thoroughly. If any burrs
are found, remove burrs with a smooth mill file,
cleaning thoroughly afterward. Temporarily attach
the top half of the flexible coupling to the motor
shaft.
11. Orient the motor conduit box in the required
position. Align the driver mounting holes with the
mating tapped holes on the discharge head. Lower
the driver until the registers engage and the driver
rests on the thrust pot assembly. Secure driver with
capscrews provided.
12. Secure the flexible coupling assembly.
13. Install the coupling guard.
14. Fill the oil reservoir with recommended oil.
