Recommended measure
Open the valve on the discharge side.
Turn on the compressor and open valves and regulator.
Check the compressor and other components.
Check and clean the air line.
Check and clean the exhaust port and muffler.
Check and clean the fluid line.
Remove, inspect and clean the pump.
Open the valve on the suction side
Confirm the configuration of the pipe and reduce the height
differences.
Check and clean the fluid line.
Dismantle the pump, check and clean.
Inspect and replace parts.
Check the compressor and configuration of the air line.
Check and clean the air line.
Adjust the discharge valve
Check the suction side so no air can enter.
Adjust air supply pressure and discharge pressure and
reduce suction height.
Adjust air supply pressure and discharge pressure. Reduce
the flow through the inlet valve to adjust pressure and flow
of the fluid.
Remove ice from the air bypass valve and check and clean
air filter. Use a pipe in the exhaust air so the ice does not
form in the muffler.
Check and clean the fluid pipe and strainer.
Check and clean the exhaust port and muffler.
Remove , inspect and clean the pump body.
