IMPORTANT
For best possible performance and continuous, satis-
factory operation, read these instructions before in-
stalling your new pump. Should service be required, this
manual can be a valuable guide, it should be kept near the
installation for ready reference.
INSTALLATION
LOCATION
Place unit as close to water source as possible to minimize
suction lift, obtain the best pumping performance, and aid in
priming. A typical portable installation is shown in Figure 1.
For permanent installation, mount unit on a foundation that
will support the weight of pump and engine and also provide
stability while the pump is running. For most permanent
installations, it is advisable to bolt unit directly to foundation.
NOTICE: Settling and/or shifting during operation can cause
piping to place excessive strain on the pump and may dam-
age pump case. Set pump on hard level surface.
SUCTION CONNECTION
Connect either rigid pipe or flexible suction hose to pump
suction as shown in Figure 1. If hose is selected, hose must
be rated to hold the suction pressure and prevent collapse
while the pump is running.
Make the suction line a continuous rise from the water
source to the pump. High spots can trap air and also make
priming difficult. Make sure all connections are tight and free
of air leaks.
NOTICE: Suction pipe or hose must be at least as large as the
pump suction inlet in order for the pump to operate properly.
Minimum depth for the suction inlet is determined by the
diameter of the suction line. See Figure 1.
NOTICE: This high pressure pump has a closed type im-
peller and will clog easily. Use a suction screen to keep
debris out of pump.
DISCHARGE CONNECTIONS
Your pump is equipped with a multiple port discharge to run
several lines at one time. Select the appropriate size for the
application. Pump output pressure will be reduced as addi-
tional lines are connected. For high pressure wash-downs or
firefighting, connect only one line. For irrigation applications
connect up to 3 small lines or one large line.
OPERATION
NOTICE: Do not start or run pump dry or damage to the
mechanical seal will result.
NOTICE: Add engine oil before startup. Refer to engine
owner/operator manual supplied with pump before startup.
PRIMING THE PUMP
A self priming pump only needs to be manually primed at the
first start-up. Once primed, under normal conditions the
pump will reprime automatically at each subsequent start-up.
If the pump is used in portable applications and the water has
been drained from the pump case, reprime before start-up
To prime, remove cap from top discharge outlet and fill pump
with water. Replace cap and start pump. The pump will

Use Concentric

friction losses.
Strainer / Foot Valve
To keep debris from entering
pump suction and to maintain
pump prime after shut-off.
Provide rigid platform
for pump.
Example:
4" Pipe x 4 = 16" minimum depth.
Eccentric Reducer
flat side up.
Depth of suction inlet not less than
four (4) times the diameter of suction
pipe to eliminate vortexing.
Use pipe, tubing, or reinforced hose to make
suction connection. Hose must have suffi-
cient strength to resist collapse under the
pressure differential that occurs while pipe
is running.
Suction pipe size should be at least one
commercial pipe size larger than opening of
pump inlet. Flow velocity should not exceed
8 ft./sec.
Suction screen area must be at least four
times suction pipe area.
All suction piping must have a continuous
rise to the pump suction inlet. A 1/4 inch per
foot minimum slope is recommended.
Piping run and connection fittings should be
properly aligned and independently supported
to reduce strain on pump case.

suction hose with
quick connect shown.
Support pipe and
fittings as required.
