DESCRIPTION and SPECIFICATIONS:

The Model MCC is a close coupled, end suction, cen-
trifugal pump for general liquid transfer service, booster
applications, etc. Liquid-end construction is cast iron and
AISI Type 316 stainless steel. Impellers are fully enclosed,
non-trimmable to intermediate diameters.
All units have NEMA 48Y or 56Y motors with square
flange mounting and threaded shaft extension.

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
CAUTION
handling pump or controls.
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 name-
plate). 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: 212ºF (100ºC) with standard
seal
250ºF (120ºC) with high
temperature seal.
Working Pressure: 75 PSI with standard seal
125 PSI with optional seals.
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.

2.1. 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
CAUTION
the pump suction and discharge connec-
tions.
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.
CAUTION
Any leakage or condensation 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.
