8. Retightening of Tie rods
- Since the dimensions of this pump may vary according to the
temperature or with the passage of time due to the
characteristics of its material: resin. Therefore, check to see if
any liquid material leaks at each sealed portion periodically,
and retighten the parts indicated with arrow marks. [Fig.8.1]
- The torque should be applied:
①
immediately before you use the pump,
②
during inspection to be performed every six months
③
during inspection to be performed every year if you use the
pump in the clean room, that is, if the pump is used within
± 5ºC of the temperature variation.
④
if any leak of liquid or material is detected with the daily
inspection.

9. Instructions for applying lubrication
9.1 Applying lubricant to the Packing
- Apply plenty of lubricant into the grove (V) of the packing.
[Fig.9.1]
＜
NOTE
＞
- Be careful that no aeration occurs when applying lubricants
.
9.2 Applying Lubricant to the Center Rod
- Apply lubricant to the whole surface of center rod. [Fig.9.2]
9.3 Assemble
- The V Packing must be installed into body with the V facing
out towards the air chambers. [Fig.9.3]
＜
NOTE
＞
- In cases where the packing is installed incorrectly air leakage
will occur.
