2. Operating principle
The APN-30/-60 GD3-W is a gas-liquid transfer pump with
a small size diaphragm.
The rotary motion of the motor is converted via a con-
necting rod to the reciprocation of the diaphragm in the
pump chamber, where the mixture of gas and liquid is
transferred from the inlet to outlet.

Instruction for use
● Do not install the pump in a
place where the pump can
get wet.
● For gas transfer, do not use
the pump in a dusty place.
Be sure to provide the inlet
with a filter to prevent foreign
matters from getting into the
pump. Otherwise, the pump
performance may reduce
or the lives of the valve and
diaphragm may remarkably
shorten.
● Do not install the pump in a
corrosive or flammable gas
atmosphere. Keep good
ventilation in a working area.
The allowable ambient and
air temperature is between
5 and 40°C. Liquid tempera-
ture should be between 10
and 40°C.
1. Before Installation

CAUTION

- 9 -
● Observe the rated voltage
specified on the name plate.
Applying any voltage than
the rated one may result in
failure.
● Surface temperature may
rise high in operation but it
dose not mean failure.
Do not touch the pump body
directly or place the objects
which may be deformed by
heat close to the pump.
● Do not tube two or more
pumps in series. It may pre-
vent the motor from starting
and lead to a burn out.

2. Installation/ Tubing/ Electrical wiring
2.1 Installation
1. Installation location
• The ambient temperature
in an installation location
should be between 5 and
40°C. Relative humidity
should be 90% or below.
Select a convenient place
for maintenance and inspec-
tion.
• Install the pump in a clear
and level place.
• Keep good ventilation. The
pump should always be free
from liquid spillage.
2. Pump fixation
Secure the pump by fixing
the base.
CAUTION
Do not install the pump on a
wobbly pedestal.
3. Tube preparation
Cut the tube ends and have
them flat before insertion.
2.2 Tubing
1. The short tubing with the
minimum bends is optimal to
reduce resistance.
2. Vinyl tubes should be resist-
ant to the pumping pressure.
CAUTION
Do not have tubing bent or
pressed. Otherwise, the tube
end may break.
Installation
Stop working upon sensing danger or abnormality.
WARNING

- 11 -
3. For liquid transfer, a suction line bore should be ø4mm or
less. Otherwise, the motor is locked by overfeeding.
A discharge line bore should also be ø4mm or less.
4. Tube size
Select proper tube size with pressure resistance, otherwise
air/liquid leaks and failure may result. Use of the braided
tube is recommended.
5. Valve mounting
Install a valve in the suction line between the pump and a
supply tank for adjusting an air/liquid flow and the degree of
vacuum.
6. Tube connection
Push the tubes into the inlet and outlet as far as it will go.
7. Tube should be thick enough. The use of a thin and light
tube may reduce suction force and an air flow.
8. Use tube bands to ensure firm connections.
NOTE: If suction line connection is imperfect, the pump sucks
air and it prevents the pump from bringing out full per-
formance.
2.3 Electrical wiring
Electrical wiring must be done by a qualified person who has
a full knowledge of safety. We are not responsible for personal
injury or property damage due to nonobservance of this warn-
ing. Contact us or your nearest distributor for wiring as neces-
sary.
■Before wiring
1. Confirm that power is disconnected before work.
2. Wiring work should be done in accordance with relevant
electric work requirements. Use the recommended wiring
accessories.
3. Observe the rated voltage specified on the name plate.
4. Install the leakage breaker as necessary. When it has func-
tioned, turn off power and check/solve problems to restore a
normal state.
●Wiring
1. DC type pumps are specifically for DC power voltage.
2. For wire colour, red is and black is . Ensure correct DC
power connections.
3. Provide a fuse for safety.
NOTE: The motor could be damaged in case the motor is over-
heated by any possibility. Be sure to equip a fuse.
Installation

- 12 -
● Dropping or subjecting the
pump to strong impact, fail-
ure may result.
Handle the pump with care.
● The pump can not start with
full discharge/suction pres-
sure or full liquid. Remove
pressure or liquid before
operation.
After a long period of stop-
page, pump performance at
the beginning of operation
becomes occasionally unsta-
ble. In this case, warm the
pump up by running pump
dry for about ten minutes.
● Always use a suction valve
to adjust an air/liquid flow.
● If the compressed air or
liquid (higher pressure
than atmospheric pres-
sure) is transferred to the
pump, sharp deterioration
to the lives of the valves,
diaphragm and bearing
may result. The suction line
pressure should be equal
to atmospheric pressure or
vacuum pressure.
● Do not use solvents such as
benzine, alcohol, thinner for
maintenance or cleaning,
otherwise a coat discolours
or comes off.

2. Pump operation
■Start-up
1. Before pump operation, check
that each tube and the outlet &
inlet are firmly connected.
2. Check that a suction line is
connected to the inlet and a dis-
charge line is connected to the
outlet.
CAUTION
If a suction line and a discharge
line are connected the other way
around, pumping process is
inverted.
3. Check that the pump is firmly
fixed on a mounting position.
4. When applying the larger volt-
age than rated one, or when the
motor is locked, the motor heats
up and the coil may break.
Do not apply an unspecified volt-
age or lock the motor.
Operation
■Operation
Operate the pump according to the following steps.
No. Procedure Contents
1Check tubing, wir-
ing and voltage.
● Check installation, tubing and wiring
are properly done and wiring system
is fused.
● Check the spec label to see if power
supply voltage is correct.
2 Open valves. ●
Fully open both discharge and suction lines.
3Supply power to the
pump.
● After checking the items 1 and 2. Turn
on power and start the pump.
● Smooth starting may not be obtained
when ambient temperature is 10ºC or
below. In this case, run the pump with
no discharge line pressure for a few
minutes to warm it up.
● Smooth starting may not be obtained
when the pump chamber is filled with
liquid. Get rid off liquid before operation.
4Adjust air flow.
● After the pump has reached a speci-
fied stroke rate, initiate full scale
operation.
● Always adjust an air flow by a suction
valve.
5
Points to be
checked during
operation
● After starting, check a pressure gauge
to see if suction and discharge line pres-
sure are correct and an air flow meter to
see if the specified air flow is obtained.
● Keep a suction line pressure at or
below atmospheric pressure.
● In case electric power has failed while
the pump is running, switch off main
power. Otherwise, the motor may not re-
start or may burn out depending on a line
pressure at the time of power recovery.
