·MAIN STRUCTURE AND USE METHOD
Ⅰ
ⅠⅠ
ⅠSTRUCTURE
This type of pump consists of gasoline/diesel engine and water pump which drove by a same
driving axle. The pump is fixed on a frame through shock absorber device, so it compact in structure
and convenience for use of movement. For structure of self-priming pump.
The pump consists of pump body, pump cover, flow guidance, impeller and seal part etc. The
pump body and pump cover are made from high quality die-casting of aluminum alloy. The flow
guidance and impeller are made from high strength cast iron, shaft sealing is machinery type sealing.
The suction and discharge pipe connector are made from engineering plastic so it can be connected
with rubber pipe.
The outlet of pump is higher than the inlet of impeller so that it can start which only need fill
water into the body of the pump. The inlet of pump is fixed with a one-way valve to prevent liquid
from being drained into water pool from the pump body which action by siphon after stop the machine.
It must guarantee store enough liquid in the pump body for next start.
The rotary direction is anticlockwise as viewed from inlet direction of impeller.

ⅡMAIN POINT OF USE
The coupling of suction pipe to the pump must be tight, reliable and no leakage.
A filter net must be added into the inlet of suction pipe as a protection , so as to avoid impurity be
sucker into the pump and stick or damage the impeller.
Prime the pump until the water overflow.
Do not run it at high speed, unless you prime it.
Drain off the pump for storage.

ⅢPROCEDURE OF USE
1. Adding water
When start the pump for the first time, it only need to add a few water into the pump and self-priming
after start, so not necessary bottom valve.
2. Start the engine, Please see manual of diesel engine or gasoline engine.

ⅣUSE AND MAINTENANCE
1.According to normal stipulation, the vacuum of pump by suction be expressed with allowable NPSH
(Net Positive Suction Head). When the pump work at the area of lower than 250m altitude. It can
estimate suction head of pump which 10m minus allowable NPSH is it. Follow increasing with
altitude, the atmosphere should be decreased, so the suction head of pump also be decreased. The
value of decrease can be estimated which 10m minus local atmosphere value is it (m water column).
2.Pipeline is better with short pipe and straight pipe, so it can decrease unnecessary loss of pipeline.
The pipeline must be supported to avoid from vibrating and damaging the pump by oppressive.
Before operation it must check connection part between pump and pipeline whether there is loose
phenomenon and special pay attention to leakage of inlet pipeline.
3.The filter net must keep a certain distance between river surface, river bottom and river bank. The
net must dip into water no less than 0.3m to avoid suction air and to keep a distance, which is not
less than 0.2m from river bottom, river bank to avoid suction stone or weeds.
4.If the gap between impeller and the surface of flow guidance is over 1mm, so that it can be

4
continuous to be used after adding an adjustment shim on the shaft shoulder.

5.When change machinery seal, be sure to apply adhesive to the connection between steel part
“#7”and pump cover. When fixed it, do not hit by force to prevent wear slice fracture.

6.When the pump is used in winter, to screw off the drain cock under the pump and draw off water
thoroughly after stop the machine to prevent from being broken by ice of freeze.

ⅤINSTALLATION OF CONNECTIVE SOFT PIPE
Set the rubber soft pipe on the connector of inlet pipe. Pay attention to, it must be set over the thread,
and then tighten it with clipper joint.
ANALYSIS OF MALFUNCTION AND REMEDY
MAL-FUNC
TION CAUSE REMEDY
Fill water is not enough Refill water into the pump.
Inlet pipe leakage. Check inlet pipe and connector of pipe, change pipe or tighten the
screw of clipper joint.
Speed of pump is too low. Check speed and find cause for
remedy.
The filter net is obstructed. Check and clean up.
It is over the capacity of pump which will
be used lift or total lift. Check the position of installation and remedy according to the cause.
The pump can not do pumping
Seal wear and leakage. Change machinery seal part.
The filter net, pipeline or impeller is
obstructed. Clean up the obstruction.
Speed is now. Increase speed.
Impeller or seal is wore seriously and the
gap is too large. Adjust the gap or change impeller and machinery seal part.
Inlet pipe leakage. Check inlet pipe and connector of
pipe, change pipe or tighten the
screw of clipper joint.
The flow of water is not
enough.
Impeller damage and leakage seriously. Change impeller into a new one.
The total lift is too high. Check cause and adjust.
There is air in the pump or inlet pipe and
seal leakage.
Screw off air drain screw cock, and
eliminate the air.
Check the pipeline or change
machinery seal part.
The flow of water is not
well-distributed and sometimes
large, sometimes small.
Speed of engine is not stability. Adjust the speed of engine.

6
There is a rub between impeller and flow
guidance.
Listen to the sound carefully,
whether the impeller is clashed with
the case and then to adjust.
Power
consumption of
pump is too
large.
The impeller is obstructed by weeds or
foreign matters. Check and clean up.
The connector of inlet pipe is loosed or
leakage. Check inlet pipeline and remedy.
No flow
suddenly
Suction head is over stipulation. Check suction head and low the
position of pump.
MAL-FUNCT
ION CAUSE REMEDY
Suction head is too high and cause
cavitation. Check suction head and lower the position of pump.
Out put of water is too large. Decrease the output of water.
Inlet pipe is obstructed by foreign body so
the resistance is too large. Check inlet pipe and filter net to clean up.
Rotary part is loosed. Listen carefully and inspect the part which cause the noise and stop the
machine to adjust.
Installing for pump unit is not stability. Stop the machine for checking and
adjusting.
There is air lay up in the pump or pipeline.
Screw off air drain screw cock and
eliminate the air.
Cause vibration or noise
Impeller damage. Stop the machine for checking and
change the impeller with a new one.
