Problem Possible cause Solution
Chattering ocurs.
Adjust the supply air pressure
and discharge pressure.
Reduce inlet flow valve to
adjusting liquid pressure and
volume.
Icing on air-switching portion.
Eliminate ice from air-
switching valve and check
and clean the air filter. Use
external exhaust hose to
control exhaust air speed.
The fluid piping (including the
strainer) is clogged with
sludge.
Check and clean the fluid
piping and strainer.
The exhaust port (silencer) of
the pump is clogged with
sludge.
Check and clean the exhaust
port and silencer.
Flow (discharge volume) is
decreased (Continued).
The pump is clogged with
sludge. Disassemble the casing,
check and clean.
The diaphragm is damaged.
Disassemble and check the
pump and replace the
diaphragm.
Liquid leakage from exhaust
port (silencer).
The fastening nuts for the
center disk are loose. Disassemble and check the
pump. Tighten the nuts.
High air consumption during
operation. The seal ring and sleeve are
worn out.
Disassemble the air-switch
portion, check and clean.
Replace parts as necessary.
The supply air pressure is too
high. Adjust the supply air
pressure.
The spool oscillates, and ball
chattering occurs.
Adjust the supply air pressure
and discharge pressure.
Reduce inlet flow valve to
adjusting liquid pressure and
volume.
Irregular noise.
The pump is clogged with
sludge particles larger than
the permissible diameter.
Disassemble the casing,
check and clean.
The supply air pressure is too
high. Adjust the supply air
pressure.
The spool oscillates, and ball
chattering occurs. Adjust the supply air pressure
and exhaust pressure.
Irregular vibration.
Connection parts and pump
mounting are loose. Check each connection part
and tighten the bolts.
