UNIT NOT DESIGNED FOR USE

WITH HAZARDOUS LIQUIDS OR

FLAMMABLE GASES. THESE

FLUIDS MAY BE PRESENT IN

CONTAINMENT AREAS.

NOTICE: INSPECT UNIT FOR DAMAGE AND

REPORT ALL DAMAGE TO THE CARRIER OR

DEALER IMMEDIATELY.

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 con-

struction 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 configura-

tions 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 mount-

ing and threaded shaft extensions. SHV units have

NEMA standard JM frame motors.

ENGINEERING DATA

Maximum Liquid Temperature: 250° F (120° C)
Maximum Working Pressure:

NPV 125 psi (9 bars)

SHV 230 psi (15 bars)

Starts per hour: 20 - Evenly distributed

INSTALLATION

NOTICE: UNIT CAN BE INSTALLED IN VERTICAL

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 main-

tained 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, avoid-

ing 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.

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.
