2. NOTICES
Not in accordance with the manual may cause
malfunction of pump or even injury of operator !
⚫Read this manual thoroughly before installation and operation.
⚫Install this pump in a place of ventilation(environmental temp. between 5~40℃).
Keep away from high temperature / high humidity / corrosive gases.
⚫Outdoor installation must give a shelter, this can effectively increase the pump`s life.
⚫This product is not explosion-proof rating, do not install in a place of potentially
gas/dust explosion.
⚫The signal line (especially the analog 4-20mA or 0-10V) cannot be configured in
parallel with the power line. The pump position should be more than 1 meter away
from the transformer, inverter, and induction motor to avoid interference.
⚫For models with I/O cables, except for the contact cables that need to be used, other

unused wires must be cut off or covered the metal ends.
⚫Do not use a inverter as power supply. This cause damage of this product.
⚫Must drain the pipe before installation. Install pump to a pressured pipe is
extremely high dangerous. It may cause a serious injure of operator.
⚫Do not operate the pump in a pressure higher than specification , or fluid viscosity
>500 cP or temperature >60℃.
⚫This unit is not suitable for all kind of fluid. Some solvents, extreme acid, high
oxidization high temperature or high viscosity fluid may cause malfunction of pump.
⚫Wear a chemical protect mask and gloves before repair or maintenance.
⚫Please do not try to modify the pump or use non-original parts. This damage pump
and cause warranty become invalid.

⚫Notices of piping (Piping configuration consult scheme 1)：
1. If pump location is above chemical container, do not excess 2.0meters higher
than the chemical lowest level in the container and check valve must be installed
vertically. High suction head may lead fail inhalation. Permissible suction head
is affected by Liquid viscosity, specific gravity, pipeline conditions.(We do not
guarantee suction head of this product)
2. When input hose is empty, pump may not able to suck liquid into pump
head automatically. In this case you can try to full the hose with liquid
then raise it up higher than pump head and start pumping. This procedure
may solve suction problem. (If a pipe injector will be install, install it after
pump can pump out normally. )
3. The pressure loss cause by pump pulse should below 1.0 Kgf/cm2 ,otherwise the
pipe start to vibrate. In this case, a pulse reducer can be installed or reduce
piping length/elbow or increase pipe diameter.
4. Be aware that pressure discrepancy between input output hose should higher
than the inner pressure loss of this pump otherwise, overfeeding even siphon
phenomenon may occur. In this case an anti-siphon/backpressure valve(both are
optional) should be installed.
5. Fluid which is easy to gasify or vaporize (Ex. H2O2, most solvents). Gas in pump
head cause variation of flow rate. In this case purge the gas through drain
valve.
6. Output pipe may install following devices to solve some problems：
Pulse damper -To reduce pipe vibration especially pipe is long/thin/plenty of
elbows
Pressure gauge -To monitor output pipe pressure.
Release valve -To prevent pipe from rupture cause by exceptional high
pressure and secure operator against hazard.
Back-pressure -To keep constant pressure of output pipe and improve flow
valve rate stability.
Pipe injector -To connect hose/pipe to other pipe.
Anti-siphon - If pumping destination altitude is lower than source
Valve tank siphon phenomenon occur. In this case an anti-siphon
valve should be installed.

3. INSTALLATION
⚫This product is suitable for universal power source(100V~240V AC/φ1/ 25Watts
RMS), but installer still need to confirm that the power source is in the range.
⚫Make sure this pump is horizontally installed.
⚫Pump base dimensions illustrate below：
1. 4 long-shape holes for M5-25 fixing
screw
2. 2 oblique-shape holes for M4、
M5、M6 fixing screw
3. Standard accessories：SUS304
M5-25 Socket head cap screw
*2+M5 nut*2+M5 plate washer*4
⚫This pump equip with 2 meters length 5-cores cable (standard) and 13-cores
cable(multifunctional model only). Use a junction box(optional) connect them to
external power source/level sensor/signal/switches.
⚫Install this pump in a place of ventilation(environment temp, between 0~40℃). Keep
away from high temperature / high humidity / corrosive gases.
⚫If operate pump continuously at high pulse rate and long period of time, the
temperature of case may reach 60℃. If you touch with bare hand you feel very hot
but this is normal. Yet if operation condition cause over-temperature-protect-switch
(inside the pump) acts frequently. You should check power source/liquid
viscosity/environment temperature/ ventilation etc. to solve this problem.
⚫Fasten the pump on a horizontal and rigid base. This prevent pump from loosing or
falling and ensure safety of operator.
⚫After install the pump, connect to pump both inlet/outlet and check valve with
standard hoses. (1/4”PVC hose，I.D.φ6.0mm，O.D. φ11mm) Keep a distance of
about 25~30cm between check valve and tank bottom to prevent from suction of
precipitations.
⚫The inlet/outlet connectors are made of plastic, use bare hand to rotate and fasten
them. Do not try to fasten connectors with tools it may break the connectors.
⚫If pump into a pressured pipe/tank, a injector ( an optional accessory ) is needed .

Code
Mode
Name
Descriptions
1.
General
Mode
The simplest(general) mode. When source power is on the
pump start to pumping. When source power is off the
pump stop synchronously.
This mode is suitable for manually operation or the pump
is controlled by a external controller.(pH/O.R.P./ Cl2 etc.)
RUN/STOP*：Toggle this switch to run / stop the pump.
DISP. ：Press this switch to change the unit of LED
display. (Note1)
▲▼：Press to increase/decrease the pulse rate, run
in highest pulse rate immediately when
press both at the same time.
2.
External

In this mode pumping pulse rate vary proportionally to the
external 4~20mA current signal.
This mode is suitable for proportionally dosing procedure.
Generally pump is controlled by a P.I.D. controller.
RUN/STOP*：Toggle this switch to run / stop the pump.
DISP. ：Press this switch to change the unit of LED
display. (Note1)
▲▼：invalid.
3.
External
0~10V Mode
(Optional)
In this mode pumping pulse rate vary proportionally to the
external 0~10 voltage signal.
This mode is suitable for proportionally dosing procedure.
Generally pump is controlled by a P.I.D. controller.
RUN/STOP*：Toggle this switch to run /stop the pump.

Multiple
Mode
(Optional)
Pumping frequency is a integer multiples to the external
voltage/on-off pulse signal. (suitable for
PC/Encoder/Probe/PLC devices which generate pulse
signal to control the pump)
For example：The pump works 4 pulses when accept 1
signal.
external signal(1p)
pump action (4p)
RUN/STOP*：Toggle this switch to run / stop the pump.
DISP. ：Press this switch to change the unit of LED
