Operation Manual -Process Pump PA5*13 Series-
Read this manual carefully and thoroughly before using.
For construction and specification etc. of this product, refer to drawing

1. Precautions
Warning Environment When using hazardous fluid, take measures to keep people away from the pump. The occurrence of external
leakage could result in serious injury.
External leakage of transported fluid Fluid might leak externally due to life of diaphragm, and this could result in human injury or equipment damage.
Take measures against leakage.
Caution Quality of supply air Place filter with filtration 5m. Use air having better quality than No.B mentioned in catalogues of Air
Cleaning Equipment.
If a large amount of foreign matter comes from air source (carbon powder, etc.), take measures such as using
special lubricant, which generates less carbon powder or using mist-separator together with this pump.
Smooth operation might be hindered by resistance increased due to foreign matter pilled up.
Quality of transported fluid When using the pump to transport liquid which contains solid matter, install strainer mount the filter with
filtration of 0.2mm at least on IN port.
Life Span and Replacement Diaphragm should be changed before the life indicated. If diaphragm should be damaged, transported fluid will
leak into the pump and damage inner components.

2. Installment
Caution Mounting Mount in horizontal posture. Otherwise, internal parts may not operate smoothly and liquid is not transported.
Tighten mounting bolts (4pcs.) securely to avoid breakage of mounting bracket due to vibration.
Piping For piping to the port FLUID IN or FLUID OUT, tighten it securely with tooling such as spanner. Use flexible tube,
not steel pipe to avoid load applied to the ports. Excessive load applied to the inner seal could cause liquid
leakage.
Flush the piping thoroughly. When installing piping or a fitting into a port, ensure that sealant material and
cutting chips of threads do not enter piping. When using sealant tape, leave the first 2 threads exposed at the
end of piping /fitting. Tightening torque Under-tightening causes liquid or air
leakage while over-tightening causes
breakage of threads and other parts. Refer
to the table below for appropriate
tightening torque.
< Description and purpose of each port >
Suction port (FLUID IN) Sucking transported fluid
Discharge port (FLUID OUT) Discharging fluids sucked into the pump. Connect to the discharge port.
Pilot air supply port (AIR SUP) Supplying pressure set by regulator. Use clean air.

PAB-OM-C007-B 3. How to use
Caution Start & Stop
Connect air piping to the port P1 P2, and transported fluid piping to the suction port FLUID IN and the
discharge port FLUID OUT respectively.
Set pilot air pressure in the range of 0.2MPa and 0.5MPa by using regulator. Keep ball valve open on the
discharge side. Whenever solenoid valve at air source is energized, air is supplied and pump starts to operate.
Set the solenoid valves operating cycle frequency in between 15Hz. Fluid flows from the suction port FLUID IN to the discharge port FLUID OUT.
To stop the pump. Exhaust pressure supplied to the pump. Pump also stops when ball valve is closed on the
discharge side. Avoid stopping the pump for long hours., as this may prevent restart of the pump. Closing
valve abruptly can generates surge, that considerably shortens the life of the pump.
Discharge Flow Adjustment
Discharge flow rate could be adjusted by changing the solenoid valves operating cycle frequency.

4. Maintenance
Caution During operation
Check liquid and air leakage, and operation conditions regularly during pump operation. If any abnormal
conditions or unclear matters are found, stop the pump immediately and contact SMC or the sales office you
purchased the pump.
Use protective tools such as anti-corrosive gloves to avoid a burn or other human injury when touching the
pump for check.
At stop
Exhaust the air on the SUP side if the pump will be stopped for a couple of hours.
Clean inside the pump to avoid clotting of transported liquid and sticking of internal parts if it will not be used
for a long period of time.
Check & Repair
Check liquid and air leakage, and operation conditions regularly during pump operation. If any abnormal
conditions or unclear matters are found, stop the pump immediately and contact SMC or the sales office you
purchased the pump.
Replace diaphragm before the indicated life cycles.
If diaphragm is broken due to the life, the operating fluid would flow out to the pilot air side. Leading to the
failure of pump.
