1. Precautions for handling

！

Warning

1) Operating environment

・When dangerous fluid or fluid possibly harmful to human is used, take measure to isolate human from

the pump. Should the external leakage of transported fluid come out, the serious damage to human
could be caused.

・When flammable or highly corrosive fluid is transported, keep the fire source away from the pump.

Otherwise, the fire and explosion could be caused.

・Prevent splash of corrosive fluid or other solvents to the external face of the pump.

・If attachment of unknown liquid is found on the external face of the pump, do not touch it without care.

2) External leakage of transported fluid

・When flammable or dangerous fluid is transported, keep the fire source and corrosive material away

from the pump. For this purpose, prepare the vessel for possible leakage and take other measures to
prevent contact with the fire source and corrosive material. Otherwise, the fire and explosion could
be caused.

・During operation of pump, the transported fluid could leak due to life out of the diaphragm. In this

case, take prevention for the leakage to avoid adverse effect to human or facility.

・Do not touch the leakage of fluid without care. If the fluid has high temperature or is chemical, the

contact could result in burn and other injuries.

3) Disassembly

・Do not disassemble the pump.

！

Caution

1) Quality of supplied air

・Mount the filter with filtration of approx. 0.01μ. For the quality of air to be used, refer to Compressed

Air Cleaning Equipments Catalog No. 5＊

＊Typical circuit shown on No.5
Compressor→HAW(after cooler)→AT(air tank)→AFF(main line filter)→IDF(refrigerating air dryer)→

AM(mist separator)→AMD(micro mist separator)→PAF

・If the amount of foreign materials generated from air supply (carbon powder etc.) is large, mount

super mist separator etc. to reinforce prevention for attachment of dust. Deposit of foreign materials
could increase resistance and prevent smooth operation.

2) Quality of transported fluid

・If it is known solid materials enter the transported fluid, mount the filter with filtration of 0.2mm at least

on fluid in.

3) Life and replacement

・Suspend operation and replace the diaphragm before it reaches the end of life. If the diaphragm

breaks, the transported fluid leaks inside the pump and exhaust port, and the internal parts of the
pump are damaged and the air blows FLUID OUT port.

Calculation of life of diaphragm（depending on operating conditions）

50 million cycles（referential life cycle）

Referential life date＝

Frequency of solenoid valve(Hz) X 60(sec) X operating time per day(hour) X 60(min.)

・The discharge amount per one cycle is about 0.050 l when there is no piping resistance. The pump

internal capacity is about 100 m l.

4) Pilot air

・Confirm the supplied pilot air is within specified range from 0.2 to 0.5MPa. The air out of this range

could cause malfunction, stop of operation, damage of internal parts and external leakage.

5) Discharge amount and suction head

・Given discharge rate and suction head are for the condition with fresh water, room temperature,

atmospheric pressure and no piping. Thus, they are varied by physical characteristic of transported
fluid, and in some cases, enough suction head can’t be obtained.

6) Max. discharge amount

・Given max. discharge rate is for the condition with supplied pressure of 0.5MPa, piping I.D. of

10mm,piping length of 0.5m, solenoid valve VQZ3000 mounted, cycle of 4Hz and no load.

7) Operating temperature

・The pump is available from 0 to 90

O

C, but should be cared not to freeze.（Avoid exposure to heat

 cycle.）

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.
Pilot air port（P1, P2） …To supply and exhaust the air at set pressure. Connect air piping.

4. How to use

！

Caution

1) Start and stop

・Connect the supply and exhaust port ”P1”, “P2” with air piping and suction port “FLUID IN” and

discharge port “FLUID OUT” with transported fluid piping respectively. If it is concerned molecular of
transported fluid permeates PTFE diaphragm and gives adverse effect on the solenoid valve, mount
compatible quick exhaust valve before the solenoid valve to prevent exposure to exhausted fluid.

・Set pilot air pressure in a range from 0.2 to 0.5MPa.

Keep the valve at discharge side open. When the solenoid valve at air supply side is energized, the
air is supplied for “P1” and “P2” and the pump starts. The solenoid valve is adjusted to switch at 2 to
4Hz. Then, after a while, the fluid starts flowing from suction port “FLUID IN” to “FLUID OUT”.

・To stop the pump, cut off the supply of air and exhaust the air inside the pump.

2) Adjustment of discharged flow rate

・The discharged flow rate is adjusted by opening and shutting level of the valve connected at

discharge side or solenoid valve. Sudden close of these valves could cause surge and shorten the
life of pump remarkably, and so must be avoided.

5. Maintenance and check

1) During operation

・During operation of pump, it is necessary to check leakage of fluid and air and operating condition

periodically. If any abnormality or concern is seen, stop the pump immediately and contact local
supplier or SMC.

・When touching the pump for maintenance, put the protective tool such as glove which isn’t affected by

transported fluid to prevent burn.

2) During stop

・If the pump is stopped for a few hours, exhaust the air at supply side.
・If the pump is left unused for extended period, clean inside of the pump to prevent adherence and

sticking of transported fluid over the time which could cause abnormal operation.

3) Check and repair

・Replace the diaphragm before it reaches referential life cycles（specified cycles）. If the pump is

continued after the life of diaphragm, the check valves of wetted part as well as the diaphragm are
deteriorated and operating failure could be caused.
