Finish Thompson VKC22 Series Installation And Maintenance Instructions Manual

ASSEMBLY
PUMPS WITH MOTORS
1. Unpack the pump, the motor, and the mounting hardware
and examine for any signs of shipping damage. If damage
is detected, save the packaging and notify the carrier im-
mediately.
2. The customer can chose to install the pump end into the
tank or lay it on its side prior to the motor installation. An
overhead hoist of some sort may be needed to install the
motor.
3. Install the coupling insert (item 11 onto the motor cou-
pling half on the motor shaft. Install the mounting plate
o-ring (item 14) into the o-ring groove on the mounting
plate and lubricate with a chemically compatible lubricant.
Insert the motor / motor adapter flange (items 1 and 3)
into the top of the pump. Note that the splines on the
pump shaft coupling half need to match up and seat into
the coupling insert. Once the coupling has seated, rotate
the motor until it is orientated correctly (avoid locating
electrical box by the discharge piping). Insert and tighten
the four bolts & washers (items 7, 8, & 9) down through
the motor adapter flange (item 3) into the mounting plate.
4. Proceed to the "installation " section of these instruc-
tions.
PUMPS WITHOUT MOTORS
1. Unpack the pump, the motor adapter flange, and the mount-
ing hardware and examine for shipping damage. If dam-
age is detected, save the packaging and contact the carrier
immediately.
2. The customer can chose to install the pump end into the
tank or lay it on its side prior to the motor installation. An
overhead hoist of some sort may be needed to install the
motor.
3. Install the motor coupling half (item 10 onto the motor
shaft so that the shaft is recessed below the face of the
coupling half. The correct recessed setting for 100/112
frame, 182/184 frame, and 215 frame motors is .170 plus
or minus .010. For 90 frame motors the recessed setting
is .100 plus or minus .010, and for 132 frame motors, it is
.125 plus or minus .010. Install the key into the key slot
and tighten the setscrews. Install the plastic coupling
insert (item 11 onto the coupling on the motor shaft.

4. Install the motor adapter flange o-ring (item 2) into the o-
ring groove in the motor adapter flange (item 3) and lubri-
cate it with a chemically compatible lubricant. Making sure
the o-ring stays in the groove place, locate the motor
adapter flange (item 3) onto the motor and bolt it down
with the correct hardware (items 4, 5, & 6).
5. Install the mounting plate o-ring (item 14) into the o-ring
groove in the mounting plate and lubricate it. Insert the
motor and motor adapter flange (items 1& 3) into the top
of the pump. Note, the splines on the pump shaft cou-
pling half need to match up and seat into the coupling
insert. Once the coupling has seated, rotate the motor until
it is oriented correctly (avoid locating the electrical box by
the discharge piping). Insert and tighten the four bolts
and washers (item 7, 8, & 9) through the motor adapter
flange (item 3) into the mounting plate.
6. Proceed to the "installation" section of these instructions.
INSTALLATION
MOUNTING
The base plate must be securely fastened so that there is no
vibration when the pump is running.
PIPING TO AND FROM THE PUMP
•
Always support the piping near the pump to minimize stress
and strain.
•
Minimize frictional losses by increasing the piping size by
one diameter.
•
Use a minimal number of bends, keeping any bends within
a distance of ten pipe diameters from the pump.
•
Install valve on the discharge lines to control flow. Place
the valve within a distance of ten pipe diameters from the
pump.
•
Ensure that the piping is leak free.
Maintain a flooded suction at all times. Use a float switch to
turn off the pump at low level
CAUTION: Do not run the pump dry. This pump should
never be started without liquid in the casing as this
could damage the pump. The fluid being transferred by
the pump lubricates the pump components. Even short
periods of running the pump dry could damage the
pump. It is recommended that run dry protection be
