DESCRIPTION and SPECIFICATIONS:

The Model HSC is a multi-stage, end-suction, centrifugal
pump for general liquid transfer service, booster applica-
tions, 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.
ALWAYS DISCONNECT ELECTRICAL
CAUTION
POWER WHEN HANDLING PUMP OR
CONTROLS.
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 name-
plate 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 name-
plate). 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:
Starts per Hour:
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
