Troubleshooting
The pump does not work.
Cause
Recommended measure
The discharge valve on the discharge side is not open.
Open the discharge valve on the discharge side.
No air supply.
Turn on the compressor and open the air valve and air regulator.
The air supply pressure is low.
Check the compressor and the configuration of the air line.
Air leaks in connecting elements.
Check the connection elements and the tightening of the screws.
The air pipes or ancillary equipment is clogged with contaminants.
Check and clean the air line.
The exhaust port (muffler) of the pump is clogged with contaminants.
Check and clean the exhaust port and muffler.
The fluid pipe is clogged with contaminants.
Check and clean the fluid line.
Pump is clogged with contaminants.
Remove, inspect and clean the pump body.
The pump runs but no fluid comes out.
Cause
Recommended measure
The valve on the suction side is not open.
Open the valve on the suction side.
Too much suction or discharge height.
Confirm the configuration of the pipe and reduce the height of the
same.
Fluid pipe discharge side (including the filter) is clogged with contaminants.
Check and clean the fluid line.
Pump is clogged with contaminants.
Dismantle the pump, check and clean.
The ball and ball seat is worn or damaged.
Inspect and replace parts.
The flow is decreasing.
Cause
Recommended measure
The air supply pressure is low.
Check the compressor and the configuration of the air line.
The air line or peripheral equipment clogged with contaminants.
Check and clean the air line.
Valve discharge side drive will not open normally.
Adjust the discharge valve discharge side.
The air mixes with the fluid.
Replenish fluid and check the configuration of the pipe on the suction
side.
Cavitation occurs.
Adjust air supply pressure and discharge pressure and reduce the
suction.
Vibrations.
Adjust air supply pressure and discharge pressure. Reduce the flow of
the inlet valve to adjust pressure and volume of fluid.
Ice formation in the air exhaust.
Remove ice from the air bypass valve and check and clean the air
filter. Use a pipe in the exhaust air that the ice does not form in the
muffler.
The fluid line (including the filter) plugged with contaminants.
Check and clean the fluid pipe and strainer.
The exhaust port (muffler) of the pump is clogged with contaminants.
Check and clean the exhaust port and muffler.
Pump is clogged with contaminants.
Remove, inspect and clean. The pump body.
