3. Installation
3-1Environmental requirement
Be sure to this pump in the following environment.
・Ambient temperature:0 ~ +40℃
・Humidity :35 ~ 85%RH
3-2Mounting unit
Make sure to fix the pump firmly.
Insufficient mounting of the pump could
fall itself and cause injury.
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.
CAUTION

3-3Wiring
Rotatory direction of a motor is only constant
direction. If the motor is reversely rotated, it
becomes an unexpected accident.
Please wiring refer to terminal connection.

Use a 8μF condenser for 100V AC motor.
If the wire to the outside touches the outside of the machine
or other objects or if it comes in contact with the hand of the
operator, use an insulated wire.
3-4Tubing connection
Connect tubing to the machine to the discharge port
(M8×1).
Use tubing good for the pressure 1.0 MPa or
higher.
Clamping torque please refer to “Tightening
level for connecting section”
After connection, make sure there is no oil leakage from the
joint.
Discharge pressure of a pump is adjusted 0.8
MPa at a relief valve.
Please do not change discharge pressure.
3-5Oil volume adjusting valve
The oil amount adjustment screw is set to the full discharge
position (maximum discharge amount) when delivered from
the factory.
Adjust the oil amount as follows.
1) Loosen the cap.
2) Loosen the needle valve by turning it counterclockwise
using a flathead screwdriver to determine the oil amount.
3) Fix the cap.

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. Maintenance
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.

5-2 Troubleshooting
When troubles occur, take the measures as defined in the chart below.
TroubleCauseMeasures to take
The motor is not runningCheck the wire
connection
Motor is rotating backward
Check the wire
connection
Low oil levelRefill the same oil in use
Refer to
“4. Lubricating oil
and refilling”
Clogged suction filterClean or replace filter, or
change oil to new oil
Refer to
“5-1 Suction filter”
Damage in the tubing
inside the pump (Twisted,
crashed, or disconnected)
Tighten or replace the
connecting parts
No oil discharged
from pump
Viscosity is too high, so
that oil can not be suckedRecheck oil in use and
replace it to proper oil
Refer to

Appendix. Oil contamination
Causes and measures
■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,
proper care must be taken since introduction of dust or
rain into the oil would lead to system malfunction.
