DANGER
WARNING
CAUTION
WARNING
Hazardous fluids
can cause fire,
burns or death.
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.
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.
NOTICE: INDICATES SPECIAL INSTRUCTIONS
WHICH ARE VERY IMPORTANT AND
MUST BE FOLLOWED.
THOROUGHLY REVIEW ALL INSTRUCTIONS
AND WARNINGS PRIOR TO PERFORMING ANY
WORK ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.
UNIT NOT DESIGNED FOR USE
WITH HAZARDOUS LIQUIDS OR
FLAMMABLE GASES. THESE
FLUIDS MAY BE PRESENT IN
CONTAINMENT AREAS.
ENGINEERING DATA
Maximum Liquid Temperature: 250° F (120° C)
Maximum Working Pressure: NPV 125 psi (9 bars)
ORIENTATION ONLY. DO NOT INSTALL WITH
MOTOR BELOW PUMP.
Unit may be mounted directly to a tank top or the optional
Goulds Water Technology mounting plate may be utilized.
Minimum and maximum liquid levels must be maintained for proper pump operation. Refer to Dimensions
page for details.
Allow adequate space for servicing and ventilation.
Protect from freezing or flooding.
PIPING
Piping should be no smaller than the pump discharge and
suction connections and kept as short as possible, avoiding unnecessary fittings to minimize friction losses.
All piping MUST be independently supported and
MUST NOT place any piping loads on the pump.
NOTICE: DO NOT FORCE PIPING INTO PLACE
AT PUMP SUCTION AND DISCHARGE
CONNECTIONS.
All joints MUST be air tight. Use 3-4 wraps of Teflon™
tape to seal threaded connections on NPV Series.
SHV Series pumps use standard ANSI 150# raised face
flanges.
NOTICE: INSPECT UNIT FOR DAMAGE AND
DESCRIPTION and SPECIFICATIONS:
The NPV and SHV Series pumps are vertically immersed,
end-suction designed pumps for general liquid transfer
service, machine tool coolant, parts washer, filtration,
waste treatment and OEM applications. Liquid-end construction is all AISI 300 series stainless steel.
These pumps are not designed for applications requiring
ANSI, FDA or NSF ratings and are not recommended for
use in highly abrasive services such as grinding.
Impellers are available in enclosed and open configurations depending on the model. Enclosed impeller versions
of the NPV are fitted with a diffuser for high efficiency
and for negligible radial shaft loading.
NPV units have NEMA 56J motors with C-face mounting and threaded shaft extensions. SHV units have
NEMA standard JM frame motors.
REPORT ALL DAMAGE TO THE CARRIER OR
DEALER IMMEDIATELY.
PIPING - SUCTION
Suction piping is not required for typical installation of
unit.
Suction intake should be above the minimum distance
from tank bottom: NPV = 2", SHV = 4". Tank must be
kept free of debris.
Use a foot valve only when necessary to hold prime
during intermittent service where tank liquid level does
not return to minimum depth before pump is re-started.
Refer to dimensions page for details.
NOTICE: IN ALL CASES, THE BEARING MUST BE
SUBMERGED IN LIQUID AT START-UP.
To avoid air pockets, no part of suction piping should be
higher than pump suction connections.
PIPING - DISCHARGE
Install a check valve suitable to handle the flow, liquids
and to prevent backflow. After the check valve, install an
appropriately sized gate valve to be used to regulate the
pump capacity, pump inspection and for maintenance.

WARNING
Hazardous voltage
can shock, burn or
cause death.
WIRING and GROUNDING
Install, ground and wire according
to local and National Electrical Code
requirements.
Install an all leg disconnect switch near
the pump.
Disconnect and lockout electrical power before
installing or servicing pump.
Electrical supply MUST match pumps name plate
specifications. Incorrect voltage can cause fire,
damage to the motor and voids warranty.
Motors not protected MUST be provided with
contactors and thermal overloads for single phase
motors, or starters with heaters for three phase
motors. See motor nameplate.
Use only stranded copper wire to motor and ground.
The ground wire MUST be at a least as large as the wire
to the motor. Wires should be color coded for ease of
maintenance.
Follow motor manufacturer's wiring diagram on the
motor nameplate or terminal cover carefully.
WARNING
Hazardous

FAILURE TO PERMANENTLY GROUND
THE PUMP, MOTOR AND CONTROLS
BEFORE CONNECTING TO ELECTRICAL POWER CAN CAUSE SHOCK,
BURNS OR DEATH.
ROTATION
NOTICE: INCORRECT ROTATION MAY CAUSE
DAMAGE TO THE PUMP AND VOIDS THE
WARRANTY.
Correct rotation is right-hand, CLOCKWISE when
viewed from the motor end. On tank mounted units,
remove motor end plug or cover, turn power on and off
quickly to observe rotation.
To reverse three phase motor rotation, interchange any
two power supply leads.

NOTICE: PUMP MUST BE FULLY PRIMED BEFORE
OPERATION. DO NOT RUN PUMP DRY OR PUMP
BEARING DAMAGE WILL RESULT.
After stabilizing the system at normal operating
conditions, check the piping. If necessary, adjust the pipe
supports.
SPLASHING OR IMMERSING OPEN
DRIP PROOF MOTORS IN FLUIDS
CAN CAUSE FIRE,SHOCK, BURNS OR

FAILURE TO DISCONNECT AND
LOCKOUT ELECTRICAL POWER
BEFORE ATTEMPTING ANY
MAINTENANCE CAN CAUSE SHOCK,
Motors have permanently lubricated bearings. No lubrication is possible or necessary. Follow the motor manufacturer's recommendations for maintenance.
If pump performance degrades due to excessive leakage,
inspect pump bearing, bushing and shaft for excessive
wear. Replace as necessary.
SEASONAL SERVICE:

piping using Teflon™ tape or equivalent on male threads
for the NPV Series.
Refer to "OPERATION" section of manual.
