Error messages
Take measures below when error messages appear during operation. Contact us or your
nearest distributor as necessary.
Error messages Possible causes Measures
Pressure overload protection is
active.
• Check a discharge line for clogging and remove
it as necessary. If this error happens during the
transfer of high viscosity liquid, make a dis-
charge line bore wider and its length shorter.
Diaphragm is broken.
• Replace the broken diaphragm with new one.
See page 59 for detail.
Sensor failure
• A sensor in the drive unit has failed. Contact us
or your nearest distributor.
Inspection
Perform daily and periodic inspection to keep pump performance and safety.
Daily inspection
Check the following points. Upon sensing abnormality, stop operation immediately and remove problems ac-
cording to "Troubleshooting".
When wear parts come to the life limit, replace them with new ones. Contact your distributor for detail.
No. States Points to be checked How to check
1 Pumping
• If liquid is pumped.
Flow meter, pressure
gauge or visual inspection
• If discharge pressure is normal. Pressure gauge
• If liquid has deteriorated, crystallized or precipi-
tated.
Visual or audio inspection
2 Noise and vibration
• If abnormal noise or vibration occurs. They are
signs of abnormal operation.
Visual or audio inspection
3
Air ingress from pump
head joints and a suc-
tion line • If leakage occurs.
• If pumped liquid includes air bubbles, check lines
for leakage and retighten as necessary.
Visual or audio inspection
Periodic inspection
Retighten the pump head mounting bolts evenly to the following torque in diagonal order.
* Mounting bolts may loosen in operation. How fast the bolts start to loosen is depending on operating conditions.
