INTRODUCTION
The horizontal multi-stage centrifugal pump is well suited
for the pumping of water in the housing, agricultural and
industrial markets. This multi-purpose pump is designed
for sprinkling/irrigation systems, washing stations,
draining/fi lling of ponds, pools, etc., and water treatment
systems. The all stainless steel wet end of this pump
features corrosion resistant material, increasing the
longevity of the pump. This pump's quiet operation makes
it very suitable for home use. The different models of the
multi-stage centrifugal pump offer a wide range of varying
fl ow rates and pressures. There is one model for highest
shutoff capability, one for highest fl ow capacity, and a
standard model for a good mix of both pressure and fl ow.
FEATURES
Pump Casing/Shell - 304 Stainless Steel
Hydraulics - 304 Stainless Steel: corrosion resistant,
multi-stage from 2 to 6 stages
Mechanical Seal - Carbon/Ceramic/VITON
Electric Motor - Square fl ange, thermally protected, dual
voltage, 115V-230V, single phase and HP's ranging
between 1/2 and 2 ensuring the proper motor is available
to meet a wide range of applications.
Shaft - 7/16 inch stainless steel hexagonal
Wire motor for correct
voltage. See "Electrical
Installation" section of this
manual and motor nameplate.

INSPECT YOUR SHIPMENT

All pumps are carefully tested, inspected, and packaged to
insure their arrival in perfect condition. When the pump is
received, examine it closely to make sure there is no
damage or broken parts that may have occurred in
shipping. If damage is evident, report this immediately to
your shipping carrier and dealer. This shipping carrier
assumes full responsibility for the shipment's safe arrival.
Any claim for damage to the shipment, either visible or
concealed, must be made through the shipping carrier fi rst.

INSTALLATION

LOCATION OF PUMP
Decide on an area for the pump installation that is
suitable based on the enclosure rating of the electric
pump motor
INDOOR PUMP INSTALLATION OPTION:
Choose a clean, well-ventilated, weatherproof location
that affords protection from freezing, fl ooding, and
excessive heat. In addition, it should provide access for
servicing and allow convenient draining of the pump,
tank, and service pipes. A prepared foundation is not
essential, provided the surface is hard and level. It can be
located in the basement or utility room of your house, at
the well or between the house and the well. When
installing outside of the house, the pump should be
protected by a pump house with auxiliary heat to
prevent possible freezing.
PIPING THE WELL
Suction tapping on the pump is 1-1/4"(1-1/2" for 45 gpm)
(FNPT) in size. Suction pipe diameter should never be
smaller than the suction tapping.
A pump performs best when installed close to the well
because suction lift and friction losses are kept to a
minimum. Although an installation near the water source
is preferred, it may be necessary or more convenient to
locate the pump away from the well, lake or stream. FOR
A SHALLOW WELL INSTALLATION, the offset is
limited only by the suction lift and the friction in the
plumbing system.
Plan your piping layout before starting the installation so
that the correct pipe and fi ttings are on hand to complete
the job. Keep the pipes clean, since pebbles and other
foreign material can block the pump impeller and hinder
operation. To avoid air pockets slope horizontal pipes
continuously upward from water source to pump by at
least 1 vertical inch for every 30" of horizontal run.
HORIZONTAL OFFSET SUCTION PIPING
When the pump is offset from the well, the horizontal
offset suction piping may have to be increased in
diameter to reduce friction loss. The friction loss in a
system increases:
