KC22/32 SERIES Sealless
Non-Metallic Centrifugal Pumps
Installation and
Maintenance Instructions
ASSEMBLY
Unpack pump from carton and check for shipping damage.
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 device 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.
ATEX COMPLIANT PUMPS
All assembly, installation, and maintenance instructions are the same as
standard pumps with the exceptions noted on page 3 under "Safety Precautions
for ATEX pumps."
PUMPS WITH MOTORS
Remove shipping plugs and insert from suction and discharge and proceed to
installation instructions.
PUMPS WITHOUT MOTORS
1. Remove wet end assembly from box.
CAUTION: Strong magnets present. Keep metal objects and
metallic chips/particles away from pump components.
2. Remove hardware package from box.
3. Install motor adapter (item 6) onto motor with labels at top
using items 10 and 11.
4. Remove drive mag assembly (item 5) from box and slide
assembly onto motor shaft making sure shaft key (item 12)
is in place. Installation dimension is .060 +/‑.010 inches as
shown in Figure 1. Tighten 2 set screws (item 5A) to 228
in‑lbs. (25.8 N‑m).
5. Gripping the discharge and the side of the impeller hous‑
ing (note above warning), carefully install the wet end into
the motor adapter. Note that the two housing studs (item
15) should be located at 3 and 9 o'clock (for 12 o'clock
discharge location) and will go through the motor adapter.
6. Install the 5/16 x 3/4 SS hex bolts (item 7), the 5/16 flat
washers (item 9), and the 5/16 hex nuts (item 8) and
tighten to 70 in‑lbs. of torque using the pattern shown in
figure 2.
7. Remove the two‑piece shipping plug from the suction.
8. Reach into the suction and spin the impeller to check if it
spins freely. If it does not, disassemble and recheck the
drive hub installation instructions in step 4.
9. Install pump into the system according to the following
installation instructions.
IMPORTANT: Verify the tightness of the set screws in the
drive magnet assembly prior to operation.
WARNING: Components can slam together from strong
magnets. Keep fingers away from area between housing
and motor adapter.

INSTALLATION
MOUNTING
Motor or base plate should be securely fastened.
PIPlNG
1. Support piping near the pump to minimize strain on pump
casing.
2. To minimize head loss due to friction:
a. Increase pipe size 1 diameter
b. Use minimal number of bends
3. Keep pipe bends a minimum of 10 pipe diameters from
suction and discharge. For example, if using 2" pipe, first
bend should be at least 20" from suction discharge.
4. Position pump as close to liquid source as possible.
5. Maintain a flooded suction.
6. Ensure that piping is leak proof.
7. Install valves on suction and discharge lines (minimum of
10 pipe diameters from pump).
8. For units in suction lift system, install appropriate piping in
discharge to allow priming of pump.
