INSPECTION AND STORAGE
When unpacking the unit, inspect carefully for any
damage that may have occurred during shipment. If
the unit is received sometime before it can be used,
it should be inspected, recrated and stored in a dry
location.
LOCATION
IMPORTANT: In installations where property damage
might result from an inoperative or leaking pump due
to power outages, discharge line blockage or any other
reason, a back-up system (s) and/or warning system(s)
should be used. Install a gate valve and union in the
suction and discharge lines. For removal of the pump
for service, close the gate valve and disconnect the
union.
1. Locate pump as close to the fluid source as
possible.
2. Place unit where the motor electrical components
and piping are protected from the weather and
extremes of heat, humidity and below freezing
temperatures.
3. Mount unit in a dry location that is easily accessible
for inspection and maintenance. If a dry location is
not available, mount it on a foundation well above
the wet floor.
4. Allow ample clearance around unit for free air
circulation.
5. Pumps incorporate a discharge port on the pump
casing that can be adjusted in 90° increments.
If necessary, adjust the discharge port to
accommodate the specific application. Pump
performance will not be affected by the position of
the discharge port.
SUCTION LIMITATIONS
1. Units are not self-priming. Normally after being
primed the total suction lift of the pump is 25
feet. Suction lift varies depending upon elevation
(altitude) and water temperature. See Practical
Suction Lift chart.
2. Where liquids at or near their boiling points are
being handled, the supply must be located above
the suction, so that the available NPSH will be
greater than that required by the unit.
PIPING
1. Use galvanized piping, rigid plastic or other suitable
pipe that will not collapse under suction or rupture
due to pressure.
2. The diameter of the suction and discharge pipe
should be no smaller than the corresponding
tappings of the pump (see Figure 1). If long runs are
encountered larger pipe should be used. Smaller
pipe will reduce the capacity of the pump.
3. All joints and connections should have Teflon tape or
pipe sealing compound (male threads only) applied
and drawn up tightly.
The entire system must be air and water tight for
efficient operation.
PUMP INSTALLATION
Refer to Figures 2, 3 and 4 for typical installations.
Both the suction and discharge pipe should be
supported at a point near the pump to avoid strains
being placed on the pump.
(
) Shut-off. To convert to feet of head, multiply by 2.31.
(
) Do not exceed the maximum case pressure and maximum liquid temperature rating of the pump.
(* ) Operation of pump in this range may result in reduced pump life and/or motor damage.

This table gives the maximum permissible suction lift or the
minimum head permitted on the suction side of a pump at
various altitudes and liquid temperatures. A minus sign before
a number indicates suction lift. A plus sign before a number
indicates minimum head. These figures are to be used as a
guide.
