Inspection
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.
Inspection items
Points to be checked
1
Noise and vibration
•
If abnormal noise or vibration occurs. They are signs of abnor-
mal operation.
2
Air ingress from pump head joints
and a suction line
• If leakage occurs.
• If pump head bolts or nuts are loose. Tighten with a torque
wrench as necessary.
3
Pressure gauge/Flow meter/Ammeter • If the rated discharge pressure, flow rate and a motor load cur-
rent on the spec labels are observed. If not, remove problems.
4
Oil gauge on the driven unit
• If an oil level is proper and oil is not leaked or deteriorated.
5
Spare pump condition
•
If it is usable. Run it from time to time to keep it ready for opera-
tion at any time when needed
.
Periodic inspection
Check wear parts such as valve set (a check valve, valve guide, valve seat and valva gasket), diaphragm and
tubing for heavy damage or wear at least every 6 months.

Measures
Check valve, valve guide,
valve seat, valve gasket,
O ring
If they are damaged or worn.
Replace as soon as possible if pump perform-
ance has reduced. Note their lives change with
operating conditions such as liquid characteris-
tics.
Diaphragm
If it is damaged or worn.
Replace as soon as possible if pump perform-
ance has reduced. Note its life changes with op-
erating conditions such as liquid characteristics.
Tubing
If it is hardened or discoloured
by ultraviolet-ray or chemical
liquid.
If it is damaged by high pres-
sure.
Replace as soon as possible if pump perform-
ance has reduced. Note its life changes with op-
erating conditions such as liquid characteristics.
Maintenance of IPM motor
An IPM gear motor used in the TD series pump is the combination of a motor and a reduction gear unit, and
the NLGI #0 extreme pressure lithium base grease is used in the gear unit. This long life grease can be used
up to 10,000 hours of operating time or 3-5 years of useful life, but then needs replaced after either period has
passed. Note replacement of the grease must be conducted by a skilled engineer. Contact us or your distribu-
tor.
