CAUTION
TO AVOID SERIOUS OR FATAL PERSONAL
INJURY OR MAJOR PROPERTY DAMAGE, READ
AND FOLLOW ALL SAFETY INSTRUCTIONS IN
MANUAL AND ON PUMP.
THIS MANUAL IS INTENDED TO ASSIST IN THE
INSTALLATION AND OPERATION OF THIS UNIT
AND MUST BE KEPT WITH THE PUMP.
This is a SAFETY ALERT SYMBOL.
When you see this symbol on the pump
or in the manual, look for one of the
following signal words and be alert
to the potential for personal injury or
property damage.
Warns of hazards that WILL cause
serious personal injury, death or major
property damage.
Warns of hazards that CAN cause
serious personal injury, death or major
property damage.
Warns of hazards that CAN cause personal injury or property damage.
NOTICE: INDICATES SPECIAL INSTRUCTIONS
WHICH ARE VERY IMPORTANT AND
MUST BE FOLLOWED.
THOROUGHLY REVIEW ALL INSTRUCTIONS
AND WARNINGS PRIOR TO PERFORMING ANY
WORK ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.
UNIT NOT DESIGNED FOR USE
WITH HAZARDOUS LIQUIDS OR
FLAMMABLE GASES. THESE
FLUIDS MAY BE PRESENT IN
CONTAINMENT AREAS.
1.3 Motors must be wired for proper voltage. Motor wir-
ing diagram is on motor nameplate. Wire size must
limit maximum voltage drop to 10% of nameplate
voltage at motor terminals, or motor life and pump
performance will be lowered.
1.4 Always use horsepower-rated switches, contactor and
starters.
1.5 Motor protection:
1.5.1 Single-phase: Thermal protection for single-
phase units is sometimes built in (check nameplate). If no built-in protection is provided, use
a contactor with a proper overload. Fusing is
permissible.
1.5.2 Three-phase: Provide three-leg protection with
properly sized magnetic starter and thermal
overloads.
1.6 Maximum Operating Limits:
Liquid Temperature: 220°F (110°C)
Working Pressure: 125 PSI
Starts per Hour: 20, evenly distributed.
1.7 Regular inspection and maintenance will increase
service life. Base schedule on operating time. Refer to
Section 8.
2. INSTALLATION
2.1 Locate pump as near liquid source as possible (below)
level of liquid for automatic operation.
2.2 Protect from freezing or flooding.
2.3 Allow adequate space for servicing and ventilation.
2.4 All piping must be supported independently of the
pump, and must “line-up” naturally.
NEVER DRAW PIPING INTO PLACE BY
FORCING THE PUMP SUCTION AND
DISCHARGE CONNECTIONS.
DESCRIPTION and SPECIFICATIONS:
The Model LC is a close-coupled, end suction, two stage
centrifugal for general liquid transfer service, booster
applications, etc. Liquid-end construction is all AISI Type
304 stainless steel, stamped and welded. Impellers are
fully enclosed, non-trimable to intermediate diameters.
Casings are fitted with diffusers for efficiency and for
negligible radial shaft loading.
All units have NEMA 48Y and 56Y motors with square
flange mounting and threaded shaft extension.
1. IMPORTANT
1.1 Inspect unit for damage. Report any damage to car-
rier/dealer immediately.
1.2 Electrical supply must be a separate branch circuit
with fuses or circuit breakers, wire sizes, etc., in
compliance with National and Local electrical codes.
Install an all-leg disconnect switch near pump.
ALWAYS DISCONNECT ELECTRICAL
POWER WHEN HANDLING PUMP OR
CONTROLS.
2.5 Avoid unnecessary fittings. Select sizes to keep
friction losses to a minimum.
2.6 Units may be installed horizontally, inclined or
vertically.
DO NOT INSTALL WITH MOTOR BELOW PUMP. ANY LEAKAGE OR CON-
DENSATION WILL AFFECT THE MOTOR.
2.7 Foundation must be flat and substantial to eliminate
strain when tightening bolts. Use rubber mounts to
minimize noise and vibration.
2.8 Tighten motor hold-down bolts before connecting
piping to pump.
3. SUCTION PIPING
3.1 Low static suction lift and short, direct, suction pip-
ing is desired. Consult pump performance curve for
Net Positive Suction Head Required.
3.2 Suction pipe must be at least as large as the suction
connection of the pump. Smaller size will degrade
performance.
3
CAUTION
CAUTION
CAUTION
3.3 If larger pipe is required, an eccentric pipe reducer
(with straight side up) must be installed at the pump.
3.4 Installation with pump below source of supply:
3.4.1 Install full flow isolation valve in piping for
inspection and maintenance.
DO NOT USE SUCTION ISOLATION
VALVE TO THROTTLE PUMP.
3.5 Installation with pump above source of supply:
3.5.1 Avoid air pockets. No part of piping should be
higher than pump suction connection. Slope
piping upward from liquid source.
3.5.2 All joints must be airtight.
3.5.3 Foot valve to be used only if necessary for
priming, or to hold prime on intermittent
service.
3.5.4 Suction strainer open area must be at least
triple the pipe area.
3.6 Size of inlet from liquid source, and minimum sub-
mergence over inlet, must be sufficient to prevent air
entering pump through vortexing. See Figures 1-4.
3.7 Use 3-4 wraps of Teflon™ tape to seal threaded
connections.

4. DISCHARGE PIPING
4.1 Allowance should be made for disconnecting dis-
charge piping near casing to allow for pump disassembly.
4.2 Arrangement must include a check valve located
between a gate valve and the pump. The gate valve
is for regulation of capacity, or for inspection of the
pump or check valve.
4.3 If an increaser is required, place between check valve
and pump.
4.4 Use 3-4 wraps of Teflon tape to seal threaded
connections.

5. ROTATION
5.1 Correct rotation is right-hand (clockwise when
viewed from the motor end). Switch power on and
off quickly. Observe shaft rotation. To change rotation:
5.1.1 Single-phase motor: Non-reversible
5.1.2 Three-phase motor: Interchange any two
power supply leads.
6. OPERATION
6.1 Before starting, pump must be primed (free of air
and suction pipe full of liquid) and discharge valve
partially open.
6.2 Make complete check after unit is run under operat-
ing conditions and temperature has stabilized. Check
for expansion of piping.
7. MAINTENANCE
7.1 Ball bearings are located in and are part of the mo-
tor. They are permanently lubricated. No greasing
required.
PUMPED LIQUID PROVIDES LUBRICA-
TION. IF PUMP IS RUN DRY, ROTATING PARTS WILL SEIZE AND MECHANICAL SEAL
WILL BE DAMAGED. DO NOT OPERATE AT OR
NEAR ZERO FLOW. ENERGY IMPARTED TO THE
LIQUID IS CONVERTED INTO HEAT. LIQUID MAY
FLASH TO VAPOR. ROTATING PARTS REQUIRE
LIQUID TO PREVENT SCORING OR SEIZING.
8. DISASSEMBLY
8.1 Complete disassembly of the unit will be described.
Proceed only as for as required to perform the maintenance work required.
8.1.1 Turn off power.
8.1.2 Drain system and flush if necessary.
8.1.3 Disconnect discharge pipe from pump.
8.1.4 Remove motor hold-down bolts.
8.2 Disassembly of Liquid End
8.2.1 Remove casing screws and nuts.
8.2.2 Remove back pull-out assembly from casing.
8.2.3 Remove the first stage diffuser cover and casing
o-ring.
8.2.4 Remove motor fan cover to expose wrench flats
or slot on shaft end.
8.2.5 Hold shaft at flats to resist rotation, and
remove impeller nut and washer.
DO NOT INSERT SCREWDRIVER
BETWEEN THE FAN BLADES TO PREVENT ROTATION.
NOTE: Notice the location of anti-rotation tabs and
holes on items 10, 11, 12 and 13 these must be
aligned and engaged for reassembly.
8.2.6 Remove the first stage impeller, impeller spacer,
intermediate diffuser and last stage diffuser
cover.
8.2.7 Remove the last stage impeller and last stage
diffuser.
NOTE: Further disassembly will require removal of the
mechanical seal. It is recommended that a new
mechanical seal be installed at reassembly.
8.2.8 Lubricate the shaft with a 50/50 solution of
glycerin and water. Remove the rotary portion
of the mechanical seal.
8.2.9 Remove the pump body and motor adapter as-
sembly from the motor.
8.2.10 Remove the stationary portion of the mechan-
ical seal from the pump body.
8.2.11 Remove the motor adapter from the pump
body.
8.2.12 To remove the pump shaft from the motor.
Heat must be applied to the pump shaft at the
largest diameter. This is required to break the
bond of the Loctite® #271 between the pump
and motor shafts.
9. REASSEMBLY
9.1 All parts should be cleaned before reassembly.
9.2 Refer to parts list to identify required replacement
items. Specify pump index or catalog number when
ordering parts.
9.3 Reassembly is the reverse of disassembly.
Observe the following when reassembling the pump:
9.4 Check the shaft runout. Maximum permissible is
.010” TIR at the end of the shaft.
9.5 Apply Loctite ‘PrimerN’ and Loctite® #271 to motor
shaft, thread pump shaft in place and torque to 30 lb.
of torque.
9.6 Lubricate pump shaft and pump body stationary seat
holder with a 50/50 glycerin and water solution prior
to installation of mechanical seal components.
9.7 Inspect casing o-ring and impeller o-rings for damage
or wear and replace if necessary.
9.8 O-rings may be lubricated with glycerin and water
solution or petroleum jelly to ease assembly.
9.9 Tighten casing screws to 10 lb.ft. of torque using a
star pattern to prevent o-ring binding.
