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.

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.
