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 cooling 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
BEFORE 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 water flow per hour at 5 - 10 psi ABOVE the dis-
charge 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.

SPECIAL PIPING SITUATIONS
Suction Lift
1. Install a priming chamber on the feed side of the pump or appropriate piping on the discharge for priming the pump.
2. Install a foot valve on the bottom of the suction piping to maintain
a prime to the pump.
CAUTION: Suction prime must be maintained at all times. Running
the pump dry will cause damage to pump components. To protect
the pump if prime is lost, use a pressure switch on the discharge,
a vacuum switch on the suction, or a motor minder to monitor
motor current draw.
PUMPING LIQUIDS WHICH MAY SOLIDIFY OR CRYSTALLIZE
Add a flush system to the pump’s piping to prevent accumulation of
material inside the pump. Install water inlet and outlet valves as shown
in Figure 1. Refer to the “Operation” section of these instructions for
the flush procedure.

codes. Motor should have an overload protection circuit.
2. Wire the motor for clockwise rotation when facing the fan end of
the motor.
3. To verify correct rotation of the motor:
a. Install the pump into the system.
b. Fully open the suction and discharge valves.
c. Allow fluid to flow into the pump. Do not allow the pump
to run dry.
d. Jog the motor (allow it to run for only one to two seconds)
and observe the rotation of the motor fan. Refer to the
directional arrow on the pump if needed.
NOTE: A pump running backward will run but at a greatly reduced
flow and pressure.
OPERATION
FLOODED SUCTION SYSTEMS
1. Fully open the suction and discharge valves.
2. If a cooling collar is used, turn on the cooling water.
3. Start the pump and verify liquid is flowing. If there is no liquid
flow, refer to the “Troubleshooting” section of these instructions.
4. Adjust the flow rate and pressure by regulating the discharge valve.
CAUTION: Never attempt to adjust the liquid flow with the suction
valve. Limiting the suction will result in damage to the pump's
components.
Water
Outlet Valve
SUCTION LIFT SYSTEMS
1. Fully open suction and discharge valves.
2. If a cooling collar is used, turn on the cooling water.
3. Prime the pump by filling the priming chamber. Allow time for any
trapped air in the suction piping to escape.
4. Start the pump. Adjust the flow rate and pressure by regulating
the discharge valve.
CAUTION: Never attempt to adjust the liquid flow with the suction
valve. Limiting the suction will result in damage to pump components.
FLUSH SYSTEMS
1. Fully close the suction and discharge valves.
2. Connect the water supply to the water inlet valve and connect a
drain hose to water outlet valve.
3. Turn on the water supply and open the inlet and outlet valves. Flush
the system until the pump has been cleared of any material buildup
(approximately 5 minutes).
4. Close the inlet and outlet valves and turn off water supply.
SEALS
SEAL REMOVAL AND INSPECTION
1. Disconnect the piping and electrical power from the pump.
2. Disassemble the pump from the motor adapter.
a. Remove the six hex-head cap screws from the impeller
housing. The impeller housing will loosen if gently tapped at
the discharge outlet.
b. Remove the protective shroud from the motor adapter.
c. While preventing the motor shaft from moving (insert a screw-
driver into the motor’s fan), unscrew the impeller cap with o-ring
and socket head bolt (Items #4,16 and 13) in a counterclockwise
rotation. Use large flathead screw driver and 5/16" hex key.
Remove the impeller, seal, cooling collar (if applicable) and
housing cover as one assembly from the motor shaft.
Note: For pumps using 90, 100/112 motor adapters, leave the
shaft adapter secured to the motor shaft.
3. Remove the seal for inspection.
a. Lubricate the impeller’s shaft with a rubber lubricant emul-
sion or soapy water to allow the seal to slide easier.
Note: Never use a petroleum product for lubrication.
Doing so will effect the seal elastomer’s performance
after reassembly.
b. If no cooling collar is present, carefully remove the retaining
ring that holds the rear of the seal. If equipped with a
cooling collar, carefully slide the cooling collar off of the
impeller’s shaft.
• With single bellows or multi-spring seals, a retain-
ing ring holds the seal in place. Carefully remove
the retaining ring. Loosen the four (4) set screw on
the multi-spring seal.
• With double seals, the cooling collar holds the seal
in place.
CAUTION: The seal’s spring is compressed and under
pressure. Use care when removing.
c. Remove the seal’s spring. Grasp the rotating head of the
seal by hand and twist to remove from the impeller’s shaft.
d. Remove the housing cover from the impeller.
e. Press the ceramic stationary seat portion of the seal out of
the housing cover.
3
4. Visually inspect all parts for damage. Replace any parts that appear
worn or damaged.
• Look for scoring of the seal’s ceramic face.
• Inspect the rotating seal face for wear.
• Check for degradation or chemical attack of any
elastomers and other seal components.
• Look for signs of heat damage (melted plastic) to the
housing cover and impeller’s shaft.
SEAL INSTALLATION AND PUMP REASSEMBLY
Single Bellows Seal
1. Install the stationary seal face.
a. Lubricate the stationary face’s o-ring with a rubber lubricant
emulsion or soapy water. Keep the polished surfaces of the
seal face clean.
Note: Never use a petroleum product for lubrication.
Doing so will effect the seal elastomer’s performance
after reassembly.
b. Carefully press the stationary face into the housing cover (use
a piece of cardboard to protect the seal while pressing
against the stationary face). The smoothest side of the station ary face should be facing outward.
2. Install the rotating face.
a. Lubricate the impeller’s shaft with a rubber lubricant emulsion
or soapy water.
b. Carefully slide the housing cover over the impeller’s shaft.
The side of the housing cover with the pressed-in seal face
should be away from the impeller.
c. Separate the rotating head of the seal from the large spring.
Re-lubricate the impeller’s shaft, then carefully slide the rotating
head of the seal over the impeller’s shaft using a twisting
motion. The carbon side of the rotating face should be toward
and pressed against the stationary head of the housing cover.
CAUTION: The carbon portion of the seal is easily
damaged. Take care not to apply uneven force or crack
the carbon while installing.
3. Install the seal’s spring and spring retainer. Compress the spring and
snap the retaining ring (item #8) into the groove on the impeller’s
shaft.
4. Install the assembled seal, impeller and housing cover onto the
motor bracket.
a. If a cooling collar is being used, slide it onto the impeller’s
shaft at this time. Take care to align the water connections
so they are accessible.
b. Install the impeller socket head bolt and cap with o-ring in a
clockwise rotation.
c. Make certain that the housing cover’s o-ring is in place.
d. Place the impeller housing into position and install the hard-
ware. Tighten the six hex-head cap screws to 90 in•lbs.
Multi-Spring Seal
The basic installation procedure for a multi-spring seal is the same as
for the single bellows seal. The exception is that a multi-spring seal has
four (4) set screws which need to be tightened on the impeller shaft.
Double Seal
1. Remove the motor adapter from the motor’s face (it is assumed
that the pump has previously been removed).
2. Install the stationary seal faces.
a. Lubricate the stationary faces’ o-rings with a rubber lubri-
cant emulsion or soapy water. Keep the polished surfaces
of the seal face clean.
Note: Never use a petroleum product for lubrication. Do
ing so will affect the seal elastomer’s performance after
reassembly.
b. Carefully press the stationary faces into the housing cover and
the cooling collar (use a piece of cardboard to protect the seal
while pressing against the stationary face). The smoothest side
of the stationary faces should be facing outward.
Note: If using a special seal material, it is vital that the
special stationary seal face is pressed into the housing cover.
3. Install the rotating faces and cooling collar to the motor adapter.
a. Carefully slide the housing cover over the impeller’s shaft.
The side of the housing cover with the pressed-in seal face
should be away from the impeller.
b. Separate the rotating head of the seal from the spring.
Note: If using a special seal material, it is vital that the
special seal face mates against the housing cover’s sta tionary face.
c. Lubricate the impeller’s shaft, and then carefully slide the
rotating face of the seal over the impeller’s shaft using a
twisting motion. The carbon or special side of the rotating
face should be toward and pressed against the stationary face
of the housing cover.
CAUTION: The carbon or special portion of the seal is
easily damaged. Take care not to apply uneven force or crack
the carbon or special material while installing.
d. Place the seal’s spring into position on top of the installed
rotating face.
e. Re-lubricate the impeller’s shaft and then carefully slide the
second rotating face of the seal over the impeller’s shaft
using a twisting motion (the carbon side of the second
rotating face should be facing away from the other rotating
face). This will require some compression of the seal’s
spring.
f. Place the cooling collar’s o-ring into position. Slide the
cooling collar onto the impeller’s shaft, with the stationary face
in the cooling collar pressed against the second rotating face.
Continue to slide the cooling collar until it mates against the
housing cover. Hold the cooling collar in this position. Take
care to align the water connections so they are accessible.
Notes:
1) The seal’s spring must be compressed further in order to
mate the cooling collar and housing cover.
2) Take care not to pinch the cooling collar’s o-ring. If
the o-ring is not properly seated, the cooling collar will leak.
4. Place the pump components onto the motor adapter. While holding
the cooling collar against the housing cover, install the assembly
into the motor adapter. The motor adapter will hold the cooling
collar in place. It will now be necessary to hold the impeller to
keep the seal’s spring compressed.
5. Carefully place the assembly in position to the motor’s face.
a. In a clockwise rotation, install the impeller socket head bolt and
cap with o-ring. It may be necessary to hold motor’s fan with a
screwdriver to keep the motor shaft from turning.
b. Align the motor adapter so that the access hole is straight up.
c. Install and tighten the impeller’s set screws through the access
hole in the motor adapter (it will be necessary to turn the impeller
to expose the holes in the impeller’s shaft).
4
d. Bolt the motor adapter to the motor using the hex-head cap
screws and lock-washers.
e. Double check the alignment of the water connection holes in the
cooling collar.
6. Install the impeller housing.
a. Install the housing cover’s o-ring.
b. Place the impeller housing into position and install the
hardware. Tighten the six hex-head cap screws to 90 in•lbs.
c. Look through the discharge of the pump to verify proper
spacing between the impeller and the housing cover.
