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.
NEVER DRAW PIPING INTO PLACE BY
FORCING THE PUMP SUCTION AND
DISCHARGE CONNECTIONS.
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.
CONTROLS.
ALWAYS DISCONNECT ELECTRICAL
POWER WHEN HANDLING PUMP OR
2.5. Avoid unnecessary fittings. Select sizes to keep fric-
tion losses to a minimum.
2.6. Units may be installed horizontally, inclined or verti-
cally.
DO NOT INSTALL WITH MOTOR BELOW PUMP. ANY LEAKAGE OR CON-
DENSATION WILL AFFECT THE MOTOR.

CAUTION
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.
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
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.
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.
5.1.1. 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.
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
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.
DO NOT INSERT SCREWDRIVER
BETWEEN IMPELLER VANES TO
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.
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
8.3.8. Repeat steps 8.3.4 through 8.3.7 for three
stage pumps.
8.3.9. Remove last impeller.
8.3.10. Remove last separator plate.
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.
