Finish Thompson GP22 Series Installation And Maintenance Instructions

ASSEMBLY
Unpack pump from carton and check for shipping damage.
PUMPS WITH MOTOR
No assembly required. Simply unpack the pump and motor and
examine for any shipping damage. If damage is detected, save the
packaging and notify the carrier immediately.
Remove the shipping plugs from the suction and discharge of the
pump and proceed to the "Installation Requirements" section of
these instructions.
PUMPS WITHOUT MOTORS
184JM MOTOR ADAPTER (STANDARD)
1. Unpack the pump and examine for any shipping damage. If
damage is detected, save the packaging and notify the carrier
immediately.
2. Prepare to install the pump onto the motor.
a. Remove the protective shroud (Item #22) from the
Motor Adapter (item #6).
b. Install key (provided) on keyway of motor and coat with anti-
seize.
3. Align pump impeller shaft with the motor shaft and key, then push
pump onto the motor.
4. Pull the socket head bolt, impeller cap and impeller cap o-ring
(Items #4, 13, 16) from the hardware bag.
a. Install the socket head bolt through the suction of the pump
with a 5/16" hex key. Coat threads of socket head bolt with
anti-seize and tighten in a clockwise rotation. It may be neces-
sary to hold the motor fan blade with a screwdriver to keep
motor shaft from turning.
b. Install the impeller cap and impeller cap o-ring using a large
flat head screwdriver in a clockwise rotation.
IMPORTANT: Do not cross thread impeller cap or leakage
could occur.
5. Now install motor adapter bolts and washers (Items #12,19) and
tighten securely.
6. Verify back of impeller is not touching the housing cover by look-
ing into the discharge of the pump.
7. Reinstall protective shroud back onto the motor adapter.
8. Install pump according to installation instructions.
90,100/112 Motor Adapters (Metric)
1. Unpack the pump and examine for shipping damage. If damage is
detected, save the packaging and notify the carrier immediately.
2. Prepare to install the pump onto the motor.
a. Remove the protective shroud (Item #22) from the motor
adapter (item #6).
b. Install key (provided) on keyway of motor and coat with anti-
seize.

Installation and Maintenance Instructions
3. Align pump impeller shaft with the motor shaft and key, then
push pump onto the motor until it bottoms out.
4. Tighten the two (2) set screws (Item #25) on the motor shaft
to 7.9 N•m (70 in•lbs).
5. Now install motor adapter bolts and washers (Items #12,19)
and tighten securely.
6. Verify back of impeller is not touching the housing cover by
looking into the discharge of the pump.
7. Reinstall protective shroud back onto the motor adapter.
8. Install pump according to installation instructions.
INSTALLATION
MOUNTING
Motor or base plate must be securely fastened.
PIPING
• Always support the piping near the pump to minimize stress
and strain on the pump's casing.
• Minimize frictional losses by increasing the piping size by one
diameter.
• Use a minimal number of bends, keeping any bends at least a
distance of ten pipe diameters away from the pump.
• Install valves on the suction and discharge lines. Place the valves
within a minimum distance of ten pipe diameters away from the
pump.
• Ensure that the piping is leak free.
• Position the pump as close to the liquid source as possible.
• Maintain a flooded suction at all times.
PUMPS WITH COOLING (PRESSURE) COLLARS
A cooling collar provides a water flush to the pump's seal. This is
necessary when pumping hot liquids or liquids that tend to build up or
crystallize around the seal faces. If your pump is supplied with a cool-
ing collar, proper water flow and pressure are critical to the operation
of the pump.
1. Plumb a water supply to the cooling collar. Use the 1/8" NPT
threaded holes for the water inlet and drain lines. Either hard pipe
or flexible tubing is suitable.
2. Adjust the water flow and pressure of the flush/cooling water BE-
FORE starting the pump.
• For pumps with bellows or multi-spring seals, supply
one to two gallons water flow per hour at 1 - 2 psi.
• For pumps with a double seal, supply one to two gallons wa
ter flow per hour at 5 - 10 psi ABOVE the discharge pressure of
the pump.
CAUTIONS:
1) Never run a pump equipped with a cooling collar without
a proper water supply. Doing so will result in damage to
the pump. Use of a flow switch is recommended.
2) Do not over pressurize the cooling collar's water supply.
Doing so can result in damage to pump components.
