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 mud.
Check and clean the air line.
The exhaust port (muffler) of the pump is clogged with mud.
Check and clean the exhaust port and muffler.
The fluid pipe is clogged with mud.
Check and clean the fluid line.
Pump is clogged with mud.
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 mud.
Check and clean the fluid line.
Pump is clogged with mud.
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 mud.
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 mud.
Check and clean the fluid pipe and strainer.

LEAKAGE OF FLUID THROUGH THE HOLLOW EXHAUST (SILENCER)
Cause
Recommended measure
The diaphragm is damaged.
Remove and inspect the pump and replace the diaphragm.
IRREGULAR NOISE
Cause
Recommended measure
The air supply pressure is too high.
Adjust air supply pressure.
The pump is clogged with sludge particles larger than the diameter allowed.
Remove, check and clean the pump body.
IRREGULAR VIBRATION
Cause
Recommended measure
The elements of connection and the support of the pump are loose.
Review each element of connection and tighten the screws.
The air supply pressure is too high.
Adjust air supply pressure.
The range and ball valve vibrates.
Adjust air supply pressure and exhaust pressure.
POWERED AIR LEAK PRESSURE OF 3 TO 8 BAR
Cause
Recommended measure
Wear directional valve.
Replace directional valve components.
NO START-UP AND IS LEAKING AIR WITHOUT CYCLES
Cause
Recommended measure
Stiff air sensors.
Change air sensor.
Wear directional valve.
Replace.
