VKC22 Series
Sealless, Non-metallic
Vertical Mag Drive Centrifugal Pumps
Installation and Maintenance Instructions
ASSEMBLY
WARNING: Magnetic field hazard. This pump contains
powerful rare earth magnets. When the pump is disassembled
(not connected to a motor) and the magnets are exposed, these
magnets produce powerful magnetic fields. Individuals with cardiac
pacemakers, implanted defibrillators, other electronic medical
devices, metallic prosthetic heart valves, internal wound clips (from
surgery), metallic prosthetic devices or sickle cell anemia must
not handle or be in the proximity of the magnets contained inside
the pump. Consult a health care provider for specific
recommendations before working with this pump.
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 immedi-
ately.
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 over-
head hoist of some sort may be needed to install the motor.
3. Install the coupling insert (item 11 onto the motor coupling
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 oriented
correctly (avoid locating electrical box by the discharge pip-
ing). 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 instructions.
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, situate 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.
