a - LACK OF SUCTION AND PUMPING CAPACITY
PROBABLE CAUSES
1- PTO not turning.
2- Lack of water in tank.
3- Filter valve closed (quick shut-off).
4- Dirty filter.
5- Obstruction in the intake hoses.
6- Air in the system.
7- Insufficient pump suction.
b - PRESSURE DEFICIENCY
PROBABLE CAUSES
1- Low PTO rpm.
2- Valve closed (quick shut-off).
3- Filter partially obstructed.
4- Intake hose partially obstructed.
5- Air in the system.
6- Pressure regulator.
7- Worn nozzles.
8- Low pumping capacity.
MAINTENANCE
TROUBLE-SHOOTING
The sprayer should be run with 540 rpm at PTO. Check visually
whether the pump is being run.
To run the hydraulic system, it is necessary to contain a minimum
quantity of liquid, otherwise there will be no pressure.
When the pump runs, liquid will pass through the valve even in the
closed position, however it will be insufficient. Open it.
Impurities in the filter prevent a free liquid flow. Clean the filter
whenever filling the tank, or with more frequency depending on the
quality of the water and the type of product applied.
Check whether the hose connecting the filter to the pump
is twisted.
Check whether there is any obstruction in the hoses from tank
to filter. Fill up the tank with water, open the valve and verify if
it flows freely.
Check the filter packing ring. The filter should not leak.
Remove the cover of the suction valves.
Check the condition of the valves and replace them if necessary.
The proper PTO rotation is 540 rpm.
When the pumps runs, liquid will pass through the valve even in the
closed position, however flow will be insufficient.
The filter should be clean to allow free liquid flow.
A deficient pump will cause depressurization. Check whether the
hose connecting the filter to the pump is twisted.
Verify whether there is any obstruction in the hoses connecting the
tank to the filter. Fill the tank with water, open the valve and observe
if it flows freely.
Check the connections and the o'rings of the tank outlet and the pump
inlet.
Check the valve and valve seat.
Check whether the nozzle flow is within the recommended
guidelines.
Replace the nozzles when the flow rate exceeds 10% of the
specified.
Use only nozzles recommended by the sprayer manufacturer.
Disconnect the pressure hose from the control valve.
Run the sprayer at 540 rpm.
Collect water for one minute and measure. The volume collected
should approximate this shown below for each pump model:
JP - 402 = 38 L/min
JP - 75 = 75 L/min
JP - 100 = 100 L/min
