UNIT NOT DESIGNED FOR USE
WARNING
WITH HAZARDOUS LIQUIDS OR
FLAMMABLE GASES. THESE
FLUIDS MAY BE PRESENT IN
CONTAINMENT AREAS.
Hazardous fluids
can cause fire,
burns or death.
DESCRIPTION & SPECIFICATIONS:
The Models NPE (close-coupled) and NPE-F (frame-
mounted) are end suction, single stage centrifugal pumps
for general liquid transfer service, booster applications,
etc. Liquid-end construction is all AISI Type 316 stainless
steel, stamped and welded. Impellers are fully enclosed,
non-trimable to intermediate diameters. Casings are fitted
with a diffuser for efficiency and for negligible radial shaft
loading.
Close-coupled units have NEMA 48J or 56J motors with
C-face mounting and threaded shaft extension. Frame-
mounted units can be coupled to motors through a spacer
coupling, or belt driven.

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., per
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: 1º F (100º C) with standard seal
50º F (10º C) with optional high
temp seal
Pressure: 75 PSI
Starts Per Hour: 0, 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. General
2.1.1. Locate pump as near liquid source as possible
(below level of liquid for automatic operation).
2.1.2. Protect from freezing or flooding.
2.1.3. Allow adequate space for servicing and ventila-
tion.
2.1.4. All piping must be supported independently of
the pump, and must "line-up" naturally.
Never draw piping into place by forcing the
CAUTION
pump suction and discharge connections.
2.1.5. Avoid unnecessary fittings. Select sizes to keep
friction losses to a minimum.
2.2. Close-Coupled Units:
2.2.1. Units may be installed horizontally, inclined or
vertically.
Do not install with motor below pump.
CAUTION
Any leakage or condensation will affect
the motor.
2.2.2. Foundation must be flat and substantial to
eliminate strain when tightening bolts. Use
rubber mounts to minimize noise and vibration.
2.2.3. Tighten motor hold-down bolts before
connecting piping to pump.
2.3. Frame-Mounted Units:
2.3.1. It is recommended that the bedplate be grouted
to a foundation with solid footing. Refer to
Figure1.
