INSTALLATION
Suction Lines
The suction line must be as short and direct as possible. When
operating pump under a suction lift condition:

To avoid air pockets which could affect pump priming, the
line must always slope upward to the pump from the liquid
source. If the line slopes down at any point along the
suction run air pockets will be created.

Hose or pipe size must match pump suction size.

The maximum vertical lift cannot exceed 20 feet (6.1
meters).

If hose is used for the suction line it must be the rigid wall
reinforced type to prevent collapse under suction.

Fittings are not recommended in the suction line.
Review all safety information located in pump safety manual.
Follow the instructions on all tags, labels and decals attached to
the pump.
Since pump installations are seldom identical, this section offers only
general recommendations and practices required to inspect, position,
and arrange the pump and piping.
Most of the information pertains to a standard static lift application
where the pump is positioned above the free level of liquid to be
pumped.
If installing in a flooded suction application where the liquid is supplied
to the pump by gravity or under pressure, some of the information such
as mounting, line configuration, and priming must be tailored to the
specific application. Be sure to limit the incoming pressure if required so
the maximum casing pressure does not exceed 180 psi (1240 kPa).
Strainers
Use a suction strainer with ¼” maximum diameter holes on end of
suction line. A suction strainer will help remove large solids that could
clog the pump impeller and casing.
Pre-installation Inspection
The pump assembly was inspected before shipment from the factory.
Before installation, inspect the pump for damage which may have
occurred during shipment or in storage. Check as follows:

Inspect pump casing for cracks, dents, damaged threads, and
other obvious damage.

Check for and tighten any loose fasteners.

Carefully read all hang tags, labels, and markings on the unit,
and follow the instructions indicated.

Check oil level in engine, follow manufacturer’s
recommendations listed in engine manual.

If unit has been stored for more than 12 months, replace
engine oil, drain any fuel and replace with fresh fuel.

Check condition of suction strainer, clean if clogged with
debris.
Discharge Lines
Use hose or piping that is rated above the maximum system line
pressure.
To reduce friction head keep line as short and direct as possible.
Make minimum use of elbows and fittings, they substantially increase
friction loss in the discharge line.
Do not terminate the discharge line at a level lower than that of the
liquid being pumped unless a siphon breaker is used in the line.
Otherwise, a siphoning action causing damage to the pump could
result.
Valves
A check valve in the discharge is normally recommended but it is not
necessary in low discharge head applications.
Positioning Pump
This pump is light weight. Pump/engine is mounted in a roll frame that
has (4) four lifting handles built in. Handle has (2) two pins installed.
The pivot pin goes through handle end plates and directly through frame
tube. Second is the lock pin, it goes through handle end plates only.
To raise and lower handles:

Remove cotter from lock pin end.

Remove lock pin.

Swing handle tube up perpendicular to frame tube.

Install lock pin, fix with cotter.

To lower handle remove lock pin, swing handle down,
reinstall lock pin.
Lift and carry pump/engine/battery only with handles. Remove suction
and discharge lines and all accessories from pump before lifting.
If a throttling valve is desired in the discharge line, use a valve as
large as the largest pipe to minimize friction losses. Never install a
throttling valve in the suction.
With high discharge heads it is recommended that a throttling valve
and a system check valve be installed in the discharge line to protect
the pump from excessive shock pressure and reverse rotation when it
is stopped.
Connections to Pump
Since even a slight leak will affect priming, head, and capacity,
especially when operating with a high suction lift, all threaded
connections in the suction line must be sealed with pipe sealant to
ensure an air tight seal. Check all hose connection gaskets; replace
any that are cracked, worn, or no longer elastic.
Mounting
Locate the pump in an accessible area as close as practical to the liquid
being pumped.
Suction Lines in Sumps/Pits
If a single suction line is installed in a sump, it should be positioned
away from the wall of the sump at a distance equal to 1-1/2 times the
diameter of the suction line.
Pump should be leveled if possible by shimming under rubber feet. For
proper pump/engine operation unit should be within 15° of level.
Continuous operation outside this limit may cause engine/pump
damage.
If there is a liquid flow from an open pipe into the sump, the flow
should be kept away from the suction inlet because the inflow will
carry air down into the sump, and air entering the suction line will
reduce pump efficiency.
System piping/hose
Flow through the system is reduced by increased suction lift, increased
discharge elevation or discharge nozzle pressure, and increased friction
losses.

Keep suction and discharge lines as short and direct as
possible to reduce friction losses. If elbows are necessary in
discharge line use long-radius type when possible.

Do not operate with coiled-up suction or discharge hose.

Do not use valves in the suction line unless absolutely
necessary.
25FP-250-00
If it is necessary to position the inflow close to the suction inlet, install
a baffle between the inflow and the suction inlet at a distance 1-1/2
times the diameter of the suction line.
Suction Line Positioning
The depth of the suction line is critical to efficient pump operation.
Make certain end of suction line is far enough under the liquid surface.

If a vortex is noticed at suction line end submerge end deeper.
the pump to rupture or explode. If overheating occurs, stop the pump
and allow it to completely cool before servicing it. Refill the pump
casing with cool liquid.
OPERATION
Review all SAFETY information in pump general safety manual.
Do not remove plates, covers, gauges, pipe plugs, or fittings from
an overheated pump. Vapor pressure within the pump can cause
parts being disengaged to be ejected with great force. Allow the
pump to completely cool before servicing.
Follow the instructions on all tags, labels and decals attached to
the pump.
Priming
Install the pump and piping as described in INSTALLATION section of
this manual. Make sure that all connections are air tight, and that the
pump is positioned level on a solid foundation.
Strainer Check
Check the suction strainer regularly, and clean it as necessary. The
strainer should also be checked if pump flow rate begins to drop. If a
suction vacuum gauge has been installed, monitor and record the
readings regularly to detect strainer blockage. Vacuum reading will
increase, at a given flow rate, if strainer becomes blocked.
Since this pump is not self-priming, it is equipped with either an
exhaust primer or a hand operated diaphragm priming pump.
Exhaust Primer
The exhaust primer utilizes engine exhaust gases directed through a
venturi to create a vacuum and draw air out of the suction line and
pump casing.
Never introduce air, steam, or high water pressure into the casing to
remove blockage in suction line or strainer. This could result in
personal injury or damage to the equipment.
Stopping
Never halt the flow of liquid suddenly. If the liquid being pumped is
stopped abruptly, damaging shock waves can be transmitted to the
pump and piping system. Close all valves slowly.
The exhaust primer is capable of priming a pump with a maximum
priming lift of 15 feet (4.6 meters). If the pump does not prime in a
reasonable length of time, check the suction line for leaks.
To prime the pump with the exhaust primer:

Close the exhaust primer handle (C27) and open ball valve
(B32) in pump suction vacuum line.

Start the engine according to engine manufacturer
instructions.

Operate the engine at maximum throttle speed and allow
primer to remove air from suction until liquid flows from
primer ejector (C7).

When the pump is fully primed, close the vacuum line valve
and release the exhaust primer handle.
If the application involves a high static discharge head, gradually close
the discharge throttling valve before stopping the pump. The pump
discharge check valve may be damaged if liquid in the discharge
piping suddenly reverses direction when the engine is stopped.
Cold Weather Preservation
In below freezing conditions completely drain the pump and piping
system to prevent damage from freezing. If the pump will sit idle for
more than a few hours remove the casing and make certain all liquid
has been drained. Clean any solids from casing.
Hand Primer
The hand primer is a positive displacement diaphragm pump. Hand
priming pump is mounted directly to roll frame on a bracket (A37) that
includes a pocket to hold the primer handle (C27). Priming relies on
the operator manually stroking the handle to remove the air from the
suction line and pump casing.
To prime the pump with the hand primer:

Remove priming pump handle from bracket and install in
priming pump.

Open ball valve (B32) in pump suction vacuum line.

Operate pump handle up and down until pump casing is full
of liquid and water starts to enter the priming pump.

When the pump is fully primed, close the vacuum line valve.

Start the engine according to engine manufacturer’s
instructions.
Once fully primed, reduce engine speed slightly and slowly open the
discharge throttling valve. The discharge line should be filled slowly to
prevent damage to the piping, hose, or gaskets. When the discharge
line is completely filled, adjust the discharge throttling valve and
engine speed until desired operating point is reached.
MAINTENANCE
Preventative Maintenance
Since pump applications are seldom identical, and pump wear is
directly affected by such things as the abrasive qualities, pressure and
temperature of the liquid being pumped, this section is intended only
to provide general recommendations and practices for preventive
maintenance. Regardless of the application however, following a
routine preventive maintenance schedule will help assure trouble-free
performance and long life from your pump.
Record keeping is an essential component of a good preventive
maintenance program. Changes in suction and discharge gauge
readings (if so equipped) between regularly scheduled inspections can
indicate problems that can be corrected before system damage or
catastrophic failure occurs. The appearance of wearing parts should
also be documented at each inspection for comparison as well. Also, if
records indicate that a certain part (such as the shaft seal) fails at
approximately the same duty cycle, the part can be checked and
replaced before failure occurs, reducing the unscheduled down time.
For new applications, a first inspection of wearing parts at 250 hours
will give insight into the wear rate for your particular application.
Subsequent inspections should be performed at regular intervals.
Critical applications should be inspected more frequently.

No leakage should be visible at pump mating surfaces, or at pump
connections or fittings. Keep all line connections and fittings tight to
maintain maximum pump efficiency.
Liquid Temperature and Overheating
The maximum liquid temperature for the pump is 180°F (82°C). Do not
apply it at a higher operating temperature than is recommended.
Overheating can occur if operated with a closed valve in the discharge
(valves should not be installed in suction line). Operating against a
closed valve could bring the liquid to a boil, build pressure, and cause
