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.

WARNING
CAUTION
NOTICE: INDICATES SPECIAL INSTRUCTIONS
THOROUGHLY REVIEW ALL INSTRUCTIONS AND WARNINGS PRIOR TO PERFORMING ANY WORK ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.
WARNING
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.
WHICH ARE VERY IMPORTANT AND MUST BE FOLLOWED.
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
wiring 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.
1.6 Maximum Operating Limits:
Liquid Temperature: 180$F (82$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.
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.
CAUTION
DISCHARGE CONNECTIONS.
NEVER DRAW PIPING INTO PLACE BY FORCING THE PUMP SUCTION AND
Hazardous fluids can cause fire, burns or death.
DESCRIPTION and SPECIFICATIONS:
The Model HSC is a multi-stage, end-suction, centrifugal pump for general liquid transfer service, booster applica­tions, etc. Liquid-end construction is cast iron, stainless steel and engineered composites.
All units have NEMA 48 Frame single-phase, 115/230 V, 60 Hz motors with C-face mounting and NEMA 56J threaded shaft extensions.
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.

strain when tightening bolts. Use rubber mounts to minimize noise and vibration.
2.8. Tighten casing hold-down bolts before connecting
piping to pump.
2.9. No field alignment of pump to motor is necessary as
pumps are close-coupled.
3. SUCTION PIPING
3.1. Low static suction lift and short, direct suction piping
is desired. Consult pump performance curve for Net Positive Suction Head Required (NPSHR), espe-
cially for lifts above 15'.
3.2. Suction pipe must be at least as large as the suction
connection of the pump. Smaller size will degrade performance.
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.
CAUTION
3.5. Installation with pump above source of supply:
3.5.1. Avoid air pockets. No part of piping should be
3.5.2. All joints must be airtight.
3.5.3. Foot valve to be used only if necessary for
3.5.4. Suction strainer open area must be at least
3.6. Size of inlet from liquid source, and minimum
submergence over inlet, must be sufficient to prevent air entering pump through vortexing. See Figures 1 through 4.
3.7. Use 3 to 4 wraps of Teflon tape to seal threaded con-
nections.
DO NOT USE SUCTION ISOLATION VALVE TO THROTTLE PUMP.

priming, or to hold prime on intermittent service.
triple the pipe area.
4. DISCHARGE PIPING
4.1. 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.
4.2. If an increaser is required, place between check valve
and pump.
4.3. Use 3 to 4 wraps of Teflon tape to seal threaded con-
nections.
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.
4
5.1.1. Single-phase motor: Non-reversible
5.1.2. Three-phase motor: Not offered.
6. OPERATION
6.1. Before starting, pump must be primed (free of air
and suction pipe full of liquid) and discharge valve partially open. Plugs are provided in the casing and valve so pump/suction piping can be filled and/or vented/drained in any pump orientation.
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.
CAUTION
ING 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.
PUMPED LIQUID PROVIDES LUBRICA­TION. IF PUMP IS RUN DRY, ROTAT-
8. DISASSEMBLY
Complete disassembly of the unit will be described. Pro­ceed only as far as required to perform the maintenance work required.
8.1. Turn off power.
8.2. Drain system and flush if necessary.
8.3. Disassembly of Liquid-End:
8.3.1. Remove casing bolts.
8.3.2. Remove motor and remaining Liquid-End as-
sembly from casing (still connected to piping) and position vertically for easier disassembly.
8.3.3. Remove impeller bolt and washer.
CAUTION
PREVENT ROTATION OF CLOSE-COUPLED UNITS. REMOVE CAP AT OPPOSITE END OF MOTOR. A SCREWDRIVER SLOT OR A PAIR OF FLATS WILL BE EXPOSED. USING THEM WILL PREVENT IMPELLER DAMAGE.
8.3.4. Remove impeller by pulling axially.
8.3.5. Remove separator plate.
8.3.6. Remove shaft sleeve.
8.3.7. Remove intermediate stage.
8.3.8. Repeat steps 8.3.4 through 8.3.7 for three
8.3.9. Remove last impeller.
8.3.10. Remove last separator plate.
DO NOT INSERT SCREWDRIVER BETWEEN IMPELLER VANES TO
stage pumps.
8.3.11. Remove seal retainer.

8.3.12. Remove shaft extension using a screwdriver in
the slot or flats in the back of the motor to pre­vent rotation and a wrench to turn extension.
8.3.13. Pry off the rotating element of the mechani-
cal seal from the motor shaft by using two (2) regular screw drivers 180º apart and using the motor adapter inner boss as a fulcrum point and then prying seal up.
8.3.14. Remove the motor adapter bolts, washers and
o-rings.
8.3.15. Remove the motor adapter.
8.3.16. Remove the stationary element of the mechani-
cal seal by pushing it out from the motor side with a blunt instrument.
9. REASSEMBLY
9.1. All parts should be cleaned before assembly.
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.
9.4. Observe the following when reassembling the liquid-
end:
9.4.1. All mechanical seal components must be in
good condition or leakage may result. Replace­ment of complete seal assembly, whenever seal has been removed, is good standard practice. It is permissible to use a light lubricant, such as glycerin, to facilitate assembly. Do not contam­inate the mechanical seal faces with lubricant.
9.4.2. Inspect the o-rings and replace if damaged.
The o-rings may be lubricated with petroleum jelly to ease assembly.
9.4.3. Inspect impellers for wear, degradation or
blockage. Clean or replace as necessary.
9.4.4. Inspect iron parts for excessive corrosion or
degradation. Replace as necessary.
9.4.5. Inspect stainless steel components for excessive
wear or degradation and replace as necessary.
9.4.6. Wear rings contained in the interstage(s) and
casing would need to be pressed or pried out and pressed in should they need replacement.
9.5. Check reassembled unit for binding and correct as
necessary.
9.6. Be sure to tighten casing bolts in a criss-cross manner
to prevent o-ring binding and cracking of the casing ears. Secure to 35 ft-lbs.
