Installation 4
SERIES C/CC CENTRIFUGAL PUMPS
The “C” and “CC” Series pumps are close coupled pumps with optional
traps. “CC” Series have cast iron volutes and adapters. “C” Series have
bronze volutes and adapters. Impellers on both series are bronze.
INSTALLATION
Location of Unit
Install pump as close to liquid source as possible, using short, simple
suction piping.
Piping should be as direct as possible; elbows and other fittings greatly
increase friction losses.
Allow service and maintenance access.
Mount on solid, rigid, vibration-free foundation.
Protect pump against flooding and excess moisture.
Piping
Pump is not self-priming. Unless liquid source level is above pump suc-
tion at all times, install a foot valve on suction pipe.
Support both suction and discharge piping independently near the pump
to avoid placing strains on pump. Start all piping at pump to avoid strains
left by a gap at last connection.
If possible, increase size of both suction and discharge piping if more
than short runs are required.
NOTICE: Never use a suction pipe smaller than the suction connection of
the pump.
NOTICE: If a reducer is necessary in the suction piping, always use an
eccentric reducer with the straight side on top.
NOTICE: BE SURE suction does not leak. Suction pipe must slope grad-
ually upward to the pump. Avoid any fittings which might cause an air
trap.
Install gate valve and union in suction and discharge lines. If complete
pump removal is required for service, close gate valves and disconnect at
unions.
Grounding the Motor
Can shock, burn or cause death.
Ground motor before working
on pump or motor.
Install, ground, wire and maintain this pump in accordance with the
National Electrical Code, Article 250, or applicable local Codes and
Ordinances.
Ground the pump permanently using a wire of size and type specified
by National or Local Electrical Code.
Connect ground wire first. Connect to ground first, then to motor termi-
nal provide. Do not connect motor to electrical power supply until unit is
permanently grounded. Any other sequence may cause serious shock
hazard. Do not ground to a gas supply line.
The motor grounding wire need not be larger than the wires supplying the
motor, provided the supply wires conform to the wiring date included in
this manual (see Table I, Page 5).
Hazardous
voltage

Installation / Maintenance 5
Wiring
NOTICE: For 575 volt installations, see motor nameplate. Consult a
licensed electrician for wiring information. Installation must meet code.
For 200, 230, and 460 volt installations, check fusing/wiring data chart
(Table I, below) before connecting pump to power source.
Check that voltage/frequency on motor nameplate are identical with volt-
age/frequency of incoming power supply.
NOTICE: Wire dual voltage motors correctly according to wiring diagram
on motor.
Check rotation of motor. Look through opening in adapter. Rotation
should be clockwise when viewed from the motor end. If not:
•Turn pump OFF and disconnect from power source.
•For three-phase motors, reverse any two leads to motor starter.
•For single phase motors, re-connect according to wiring diagram on
motor.
Priming the Pump
NOTICE: NEVER run pump dry. To run pump dry may damage seals.
To Prime:
1. If pump is installed below liquid source level, open gate valve in suc-
tion line and flood suction.
2. If pump is not installed below liquid source level, fill pump through a
tee installed in pump discharge and fitted with a priming plug in the
upright position.
Tighten priming plug securely after priming!

*A Fusetron is recommended instead of a fuse in any motor circuit.
IMPORTANT: BE SURE lead wire opening on end of
motor is fully sealed when conduit or a pressure switch
is not used. Failure to seal it properly will allow dirt, rain,
bugs, etc. to enter back compartment of motor through
conduit opening and cause switch malfunction.

MAINTENANCE
Little or no maintenance to pump is required other than possible replace-
ment of shaft seal after a reasonable period of operation (see below).
Lubricate motor according to motor manufacturer’s instructions. Periodic
greasing is required for most motors.
PUMP STORAGE
Drain pump to prevent freezing.
Keep motor dry and loosely covered. Do not wrap with plastic sheeting;
trapped moisture could cause corrosion or insulation deterioration.
NOTICE: Agood rust inhibitor in the liquid end of cast iron pumps is rec-
ommended to prevent excessive corrosion.
PUMP START-UP AFTER STORAGE
Replace all drain plugs and close all drain valves in system.
Be sure all connections are tightly sealed.
After inital check is made, fill pump according to “Priming the Pump”
above.
SHAFT SEAL REPLACEMENT
NOTICE: The highly polished and lapped faces of the seal are easily
damaged. Follow instructions and handle the seal with care.
Be sure unit is grounded and power
disconnected before attempting any
work on pump or motor.
REMOVAL OF OLD SEAL
Refer to Figure 1 for Mechanical Seal parts identification.
1. Remove motor hold down bolts and bolts holding adapter/seal plate to
volute. Slide motor, adapter/seal plate and impeller backward to clear
volute.
2. Remove impeller screw and washer from end of shaft and slide
impeller off of shaft.
3. Unbolt adapter/seal plate from motor.
4. Use two screwdrivers (Figure 2) or bearing puller to carefully separate
motor from adapter/seal plate, bringing rotating half of seal off with
adapter/seal plate. Shaft sleeve may come off with seal.
5. Use hammer, if necessary, to drive shaft sleeve out of seal. Clean up
shaft sleeve with emery paper if necessary.
6. Place adapter/seal plate face down on bench and drive old stationary
half of seal out of adapter/seal plate by carefully tapping with screw-
driver and hammer (Figure 3).
7. Use a wire brush to thoroughly clean adapter/seal plate cavity. Be sure
all dust and grime are out of seal cavity before installing new seal.

Maintenance 7
INSTALLING NEW SEAL
1. NOTICE: Seal faces are highly polished and lapped. Handle with
care. Any mar, nick or scratch on seal face will cause it to leak.
BE SURE to install with polished faces toward each other.
2. Clean polished surface of ceramic seat with clean cloth.
3. Wet O-Ring around ceramic seat with liquid soap.
4. Press stationary (ceramic) half of seal cavity into cavity firmly and
squarely with thumb pressure. If it does not seat properly, remove and
place seal face up on bench. Re-clean adapter/seal plate cavity. Seal
should now seat correctly.
5. If seal does not seat after re-cleaning adapter/seal plate cavity, place
a cardboard washer over polished face of seal and carefully press
into place using a piece of 1” standard pipe as a press (Figure 4).
NOTICE: BE SURE you do not scratch seal face.
6. Dispose of cardboard washer and recheck seal face to be sure it is
free of dirt, foreign particles, scratches and grease.
7. Inspect shaft and shaft sleeve to be sure they are clean.
8. Re-install O-Ring, shaft sleeve and slinger on shaft.
NOTICE: Asmall amount of grease or Never-Seez under shaft sleeve
will help prevent shaft and sleeve from freezing together when pump
is in service.
9. Remount adapter/seal plate to motor, being careful not to scratch seal
face.
10. Apply liquid soap to inside diameter and outside face of rubber drive
ring on rotating half of seal.
11. Slide seal assembly onto shaft sleeve (sealing face first) far enough
so that seal spring is located on shaft sleeve.
NOTICE: Be careful not to nick carbon seal face when passing it
over end of shaft sleeve.
12. Slide impeller and gaskets onto shaft with key in position. Be sure to
maintain proper order as shown in Exploded View, Page 9.
13. Install washer and impeller screw on end of shaft and tighten screw
until it is snug. This should locate seal in place and bring seal faces
together.
14. Reinstall motor, adapter and impeller assembly on volute, using new
gasket.
15. Reinstall motor hold-down bolts.
16. Check all bolts for tightness.
