2. Precaution for installation
Caution
1) Mounting
- Only horizontal mounting is available. When the pump is not mounted horizontally with its bottom
faced down, it may cause sucking failure.
- Use two M5 bolts (four M6 bolts for foot bracket) to mount the pump. If the bolts are not tightened
firmly, the pump could be exposed to the vibration and eventually damage.
2) Piping
- Perform flushing enough for piping to avoid intrusion of cutting chips and sealant debris created
by screwing the piping and fitting. If the tape is used for sealing, leave two threads exposed.
3) Material of fitting
- The threaded part is made of resin. Thus, do not tighten the metal fitting to avoid collapse of the
thread.
4) Tightening torque
- Insufficient tightening torque could cause external leakage and excessive one could damage
threaded part and parts. Keep adequate value for tightening.

3. Description and function of individual port
Suction port(FLUID IN)
…
To suck transported fluid. Connect suction piping.
Discharge port(FLUID OUT)
…
To discharge fluid sucked inside the pump. Connect discharge
piping.
Air supply port (AIR SUP)
…
Supply compressed air set by regulator etc.
Air exhaust port (AIR EXH)
…
Exhaust pilot air.
4. How to use
Caution
1) Start and stop
(1) Press manual pin.(Only at first operation)
(2) Connect air piping to air supply port
”AIR SUP”, and fluid transfer piping to suction port “FLUID
IN”
・
discharge port
”FLUID OUT”.
(3) Set pilot air pressure within 0.2 to 0.5MPa by regulator. Pump operates when 3 port solenoid
valve on air supply port
“AIR SUP” is energized, exhausting noise generated from air exhaust
port
“AIR EXH”, and fluid flows from suction port “FLUID IN” to “FLUID OUT”.
At this time, ball valve on discharge side is open. It sucks by itself without priming. To restrict
exhausting noise, mount silencer (AN20-
02 option) on air exhaust port
“AIR EXH”.
(4) Exhaust air supplied from 3 port solenoid valve on supply port
“AIR SUP” to stop pump.
