■System application
The ACM-Ⅱcontinuous delivery motor driven gear pump delivers a
relatively small amount of oil for lubrication from the distributor to
the lubrication points.
Do not use this system for any other purposes.
■Marks used in manual
In this manual, safety precautions are provided using the marks
below in order to prevent accidents which might cause injuries to
human bodies. Be sure to carefully read these safety precautions to
understand the contents thoroughly before handling the pump.

Make sure to fix the pump firmly.
Insufficient mounting of the pump could

Mount and fix the pump firmly using four (4) M6
bolts.
LUBE recommends anti-vibration rubber
to be applied when the pump is exposed to
vibration.
Be sure to allow necessary space around the
pump for operation and maintenance.

  4. Lubricating oil and refilling
     
4-1 Lubricating oil to be used
Use industrial lubricating oil in the range from 32 to
1300 mm2/s of ISO viscosity.
Do not use any lubricating oil other than that
which has been recommended.
Use lubricating oil of the same grade made by the
same manufacturer.


4-2 Refilling lubrication oil
When the oil in the tank reaches the Ｌlevel on the oil
level gauge provided, refill the tank with more oil, up to
the Ｈlevel, from the refill port on the pump flange.
      Use new lubricating oil. If lubricating oil contains
any foreign substances, clogging may occur,
causing the pump to stop discharging oil.
Refill it through the refill port that you find above the
pump flange.
Keep checking the oil level gauge provided when refilling
the tank with oil.
If lubricating oil overflows or leaks, wipe off the
overflowing or leaking oil.

5-1 Suction filter
Replace or clean filter once a year.
Before conducting maintenance on the pump, turn
off the power and make sure that the pump is not
operating. Conducting maintenance with the power
turned on will increase the risk of the operator
getting an electric shock or the fingers being
pinched in moving parts of the pump drive unit.
Proper lubrication cannot be expected if the
suction filter is clogged or become dirty because
oil may not sucked well Clogged or dirty suction
filter may cause over load, too.
When oil is reused, remove sediments in the
tank. Otherwise, sediments will flow to the
pump suction opening and may clog the suction
filter.

■Causes

Causes for contamination can be divided into two categories.

○Before the completion of installation
  Foreign particles in the tubing or pump tank.
（Manufacturing defects of the assembly parts or
connecting parts and unconformity during construction.）

○During operation
  Foreign particles from outside or generated inside of
the system.
（Condensation of the moisture in the air due to change in
temperature or sludge by oxidation of lubrication oil
itself.）


■Measures

1. Clean the tank and remove the foreign particles.

2.Keep the oil for refilling in the proper place.
 If the system is installed and/or oil is stored outdoors,
