Care of Component Materials Waukesha Cherry-Burrell® Brand C-Series Pump
Page 8 95-03008-IEC 01/2019
Care of Component Materials
NOTE: SPX FLOW recommends the use of an FDA-approved anti-seize compound on all threaded
connections.
WARNING
Failure to comply with the Care of Component Materials could lead to bodily injury.
Stainless Steel Corrosion Corrosion resistance is greatest when a layer of oxide film is
formed on the surface of stainless steel. If film is disturbed or
destroyed, stainless steel becomes much less resistant to corro-
sion and may rust, pit or crack.
Corrosion pitting, rusting and stress cracks may occur due to
chemical attack. Use only cleaning chemicals specified by a repu-
table chemical manufacturer for use with stainless steel. Do not
use excessive concentrations, temperatures or exposure times.
Avoid contact with highly corrosive acids such as hydrofluoric,
hydrochloric or sulfuric. Also avoid prolonged contact with chlo-
ride-containing chemicals, especially in presence of acid. If chlo-
rine-based sanitizers are used, such as sodium hypochlorite
(bleach), do not exceed concentrations of 150 ppm available
chlorine, do not exceed contact time of 20 minutes, and do not
exceed temperatures of 104°F (40°C).
Corrosion discoloration, deposits or pitting may occur under prod-
uct deposits or under gaskets. Keep surfaces clean, including
those under gaskets or in grooves or tight corners. Clean immedi-
ately after use. Do not allow equipment to set idle, exposed to air
with accumulated foreign material on the surface.
Corrosion pitting may occur when stray electrical currents come
in contact with moist stainless steel. Ensure all electrical devices
connected to the equipment are correctly grounded.
Elastomer Seal
Replacement Following
Passivation
Passivation chemicals can damage product contact areas of this
equipment. Elastomers (rubber components) are most likely to be
affected. Always inspect all elastomer seals after passivation is
completed. Replace any seals showing signs of chemical attack.
Indications may include swelling, cracks, loss of elasticity or any
other noticeable changes when compared with new components.

DANGER
Installation
The pump contains internal moving
parts. DO NOT put hands or fingers into
the pump body ports or drive area at any
time during operation. To avoid serious
injury, DO NOT install, clean, service, or
repair the pump unless all power is off
and locked out and the pump is de-
pressurized.
Unpack all parts of your equipment and inspect for damages that
may have occurred during shipping. Report any damage to the
carrier. See “Shipping Damage or Loss” on page 6.
All ports are covered at the factory to keep out foreign objects
during transit. If the covers are missing or damaged, remove the
pump cover and thoroughly inspect the fluid head. Be sure the
pumping head is clean and free of foreign material before rotating
the shaft.
Pump Location 1. Locate the pump as near as practical to the liquid supply.
2. Keep the supply piping short and straight to keep the pump
supplied with liquid and prevent damaging cavitation.
3. Locate the pump so that it is accessible for service and
inspection during operation.
4. Protect the motor from flooding.
Pump Leveling Level the pump by loosening the setscrews (Figure 2, item A) to
adjust the length of the legs.

Supply and Discharge
Piping/Valves
CAUTION
Install the pump and piping system in accordance with local
codes and restrictions. Practices described in this manual are
recommended for optimum performance.
• Use a line size equal to or larger than the connection size on
the pump, especially the inlet supply line.
• Keep the supply line as short and as straight as possible by
minimizing the use of elbows and valves. Avoid up and down
rises that trap air.
• Be certain all joints in the suction line are well-sealed to
prevent air leaks.
• Maintain a straight length of pipe (Figure 3, item A) at least 8
pipe diameters long at the pump inlet.
• The pump casing on the C-114 through C-328 may be
rotated with the discharge connection pointing in any
direction; the best pump performance will be with the outlet
up, to the left, or 45 degrees in between. These positions
ensure a flooded casing and prevent problems caused by air
in the system. See Figure 4.
• Seal all joints in the suction line well to prevent air from being
sucked into the system.
• If an expansion joint is used, install a pipe anchor between it
and the pump.
• The slope of the line depends on the application
requirements; the best pump operation is with the supply line
sloped slightly upward toward the pump to prevent trapped
air. If the system must drain into the pump casing, keep the
downward slope to a minimum or priming problems may
occur. See Figure 5.
• Support the supply and discharge piping near the pump so
that no strain is put on the pump casing. See Figure 5, item
A.
• Install shutoff valves to isolate the pump from the supply and
discharge lines to allow the pump to be serviced without
draining the system.
WARNING
The pump and piping may contain sharp edges. Wear gloves to
help avoid injuries from these hazards.

Figure 4 - Recommended Discharge
Positions
Figure 5 - Pipe Supports

Installation Waukesha Cherry-Burrell® Brand C-Series Pump
Page 14 95-03008-IEC 01/2019
• If a reducer is connected to the inlet, use an eccentric type to
prevent problems due to trapped air. See Figure 6.
• This pump is not self-priming. If the pump is installed above
the supply liquid level, install a foot valve or other system
check valve (Figure 7, item A) to keep the system flooded for
priming.
• A throttling valve may be required to control the pump flow
rate to prevent motor overload. Always install a throttling
valve (Figure 7, item B) in the discharge piping and at least
10 diameters from the pump outlet. NEVER install a throttling
valve in the supply piping (Figure 7, item C).
Installations that may
cause operation problems
• Any system throttling valves or similar devices to control flow
rate must be installed in the discharge line. DO NOT install
any system throttling valves or similar devices to control the
flow rate in the supply line. (See Figure 7.) Restriction in the
supply line may cause cavitation and pump damage.
• “Water hammer” in the system can damage the pump and
other system components. Water hammer often occurs when
valves in the system are suddenly closed, causing lines to
move violently with a loud noise. One way to eliminate water
hammer is to slow down the actuation speed of the valve.
• Do not expose the pump to freezing temperatures with liquid
in the casing. Frozen liquid in the casing will damage pump.
Drain the casing before exposing it to freezing temperatures.

Electrical Connections
DANGER
The pump contains internal moving parts. DO NOT put hands or
fingers into the pump body ports or drive area at any time during
operation. To avoid serious injury, DO NOT install, clean, service,
or repair the pump unless all power is off and locked out and the
pump is de-pressurized.
CAUTION
The motor must be installed by qualified personnel, e.g., a
licensed electrician.
• Read the motor manufacturer's instructions before making an
installation. Follow the manufacturer's lubrication schedules.
Check the motor nameplate to be sure that the motor is
compatible with the electrical supply and all wiring, switches,
and starters. Make sure all overload protections are correctly
sized.
• Check the pump rotation following an electrical installation.
The correct direction of rotation is counterclockwise when
facing the pump inlet connection. See Figure 4 on page 13
and label 33-34 in Figure 8.
Before First Startup Clean Pump and Piping
Disassemble the pump and clean all product contact parts and
seal parts prior to first operation. Follow instructions in the
“Cleaning Safety Procedures” on page 15 and “Pump Disassem-
bly - Pin Impeller Design” on page 20 or “Pump Disassembly -
Sealed Impeller Design” on page 32. Thoroughly clean the pump
of any materials that could have accumulated during installation.
Cleaning Safety
Procedures
Manual Cleaning
• Do not use toxic and/or flammable solvents.
• Lock out electrical power and shut off all air prior to cleaning
the equipment.
• Keep electrical panel covers closed and power off when
washing the equipment.
• Clean up spills as soon as possible.
• Never attempt to clean the equipment while it is operating.
• Wear proper protective clothing.
Cleaning-In-Place (CIP)
1. Make certain that all connections in the cleaning circuit are
properly applied and tightened to avoid contact with hot water
or cleaning solutions.
2. When the cleaning cycle is controlled from a remote or auto-
mated cleaning center, establish safe procedures to avoid
automatic start-up while servicing equipment in the circuit.

Installation Waukesha Cherry-Burrell® Brand C-Series Pump
Page 16 95-03008-IEC 01/2019
Preliminary Test Run
Test the system using a preliminary run with the materials that will
be pumped. DO NOT run the pump to produce final product at
this time. See “Starting the Pump” on page 17.
Check for Possible Motor Overload Condition
Certain combinations will overload the motor when operated with
open unrestricted discharge, resulting in an unacceptably high
flow rate. Additional discharge restriction may be required to
lower the flow rate and lower the horsepower requirement. DO
NOT add any restriction to the supply line. If the pump was incor-
rectly selected, a smaller impeller or a higher motor horsepower
may be required. If you are uncertain about pump selection and
application, temporarily install an ammeter in the electrical ser-
vice.
Ammeter Test
Operate the pump under process conditions and check the motor
amp draw versus the nameplate full load rating. If the amp draw
exceeds the motor rating, a system change or pump change is
required. If the process conditions and/or liquid changes (higher
viscosity, higher specific gravity), recheck the motor amp draw.
Contact your authorized SPX FLOW distributor for assistance.
CAUTION
The motor must be installed by qualified
personnel, e.g., a licensed electrician.

Operation
Important Safety
Information
DANGER
The pump contains internal moving parts. DO NOT put hands or
fingers into the pump body ports or drive area at any time during
operation. To avoid serious injury, DO NOT install, clean, service,
or repair the pump unless all power is off and locked out and the
pump is de-pressurized.
WARNING
The pump components and piping may contain sharp edges.
Handle the impeller carefully because edges may be sharp. Wear
gloves while installing and servicing the pump to help avoid
injuries from these hazards.
CAUTION
These pumps and will be severely damaged if operated with
closed valves in the discharge or inlet lines. The pump warranty
is not valid for damages caused by a hydraulic overload from
operation or start-up with a closed valve in the system.
CAUTION
The motor must be installed by qualified personnel, e.g., a
licensed electrician. Motor maintenance, repair and wiring are not
covered in this manual. For specific information, contact the
motor manufacturer.
Ensure that the pump is correctly installed as described in “Instal-
lation” on page 12.
Starting the Pump 1. If the pump has a flush seal option, start the flow of flush
water (recommended rate is approximately 5 US gallons per
hour (18,9 liters per hour) before operating the pump.
2. Before starting the pump, prime the pump by flooding the
pump casing with liquid to avoid damaging the pump parts.
Depending on the installation, refer to the priming instructions
on page 18.
3. Start the pump motor.
4. Check the pump to ensure that the liquid is flowing and that
all piping connections and seals are leak-free.
5. Make sure that the pump is not operating against a closed
discharge. Continued operation against a closed discharge
will heat the liquid in the casing to boiling and lead to pump
damage.
6. Slowly open the discharge valve until the desired flow is
obtained. Observe the pressure gauges. If pressure is not
attained quickly, stop the pump and prime it again.

2. Open the discharge valve to vent any air trapped in the sup-
ply line or casing (see Figure 9, item C).
3. Resume the “Starting the Pump” procedure on page 17, at
step 3.
Priming the Pump with the Feed Source Below
Pump Level
The pump will not self-prime if the liquid supply is below the pump
level. If the liquid supply is below the pump level, provide an out-
side source for priming.
1. Close the discharge valve (see Figure 10, item C) and open
the air vents.
2. Open the valve in the outside supply line (see Figure 10, item
A) until liquid flows from the vent valves.
3. Close the vent valves.
4. Close the outside supply line.
NOTE: Use a type of check valve system (see Figure 10, item B)
to keep the supply line and pump casing flooded with liquid;
otherwise the pump must be primed before each operation.
5. Resume the “Starting the Pump” procedure on page 17, at
step 3.
Stopping the Pump
T1. To stop the pump, shut off power to the pump motor.
NOTE: Liquid in the system can flow freely through the pump; the
pump does not act as a shutoff valve.
2. Shut off the supply and discharge lines.

DANGER
The pump contains internal moving parts. DO NOT put hands or
fingers into the pump body ports or drive area at any time during
operation. To avoid serious injury, DO NOT install, clean, service,
or repair the pump unless all power is off and locked out and the
pump is de-pressurized.
WARNING
The pump components and piping may contain sharp edges.
Handle the impeller carefully because edges may be sharp. Wear
gloves while installing and servicing the pump to help avoid
injuries from these hazards.
CAUTION
Make sure to keep the work area clear of machine parts, tools,
product lines, foreign materials, and power cables to avoid
potential hazards.
CAUTION
Make sure appropriate lighting is available: at least 1000 lux,
independent of daylight and weather conditions.
CAUTION
Before carrying out any maintenance and repair work on cold
components, ensure that the machine parts in question are
sufficiently heated. The contact temperature of accessible
machine parts must not be lower than those in the EN ISO
13732-1.
Before detaching port connections to the pump:
• Close the suction and discharge valves.
• Drain the pump and clean or rinse, if necessary.
• Disconnect or shut off the electrical supply and lock out all
power.
Scheduled Maintenance A routine maintenance program can extend the life of your pump.
Keep maintenance records. These will help pinpoint potential
problems and causes.
Routine Maintenance
• Check for unusual noise, vibration and bearing temperatures.
• Inspect the pump and piping for leaks.
• Check the mechanical seal area for leakage (no leakage is
desired).
• Check the backplate gasket for wear/damage.
• Lubricate the bearings (see motor manufacturer for correct
specifications).
• Monitor the seals.
• Perform vibration analysis.
• Check the discharge pressure.
• Monitor the temperature.
