1. SAFETY
All safety instructions must be observed and followed.
2. Before Using
2.1. There is high speed rotating components. Failure to follow the
safety instructions may lead to serious injury. All safety instructions
must be observed and followed strictly.
2.2. Before installing and starting the barrel pump, the related
engineer must have the considerable qualification and is familiar
with this manuals.
2.3. The installation and maintenance must according to the current
machinery and electrical standard strictly.
2.4. The spare parts life time will be limited by wear and corrosion.
The failure is affected by operating environment. The user has the
responsibility to operate in accordance with the regulations. The
regular maintenance and spare parts change should be performed
regularly. Stop the pump when the pump under irregularity and
obviously dangerous status.
2.5. The pump should install the detection alarm system when it
was installed at the location where may cause the failure or
personal injury.
3. Using
3.1. Wear protective clothing, goggles and in accordance with the
safe production routine when operate the corrosive and hazardous
substance.
3.2. It is prohibited to use plastic or aluminum alloy pump pipe and
the non-explosion proof motor when transferring the flammable
liquids.
3.3. Carry flammable liquids, the earth wire must be installed,
electrostatic protection device and conductive hose must be used
when transferring the flammable liquids.
3.4. Make sure the pump head insert to the liquids completely
before using. Also all the connectors connect tightly. Without
leakage and fall out dangerous situation.
3.5. The suitable flexible pipe must be used during transferring high
temperature liquids.
3.6. Attention to the pumped liquids temperature, viscosity and
density do not exceed the stated upper limit.

4. MACHINE DESCRIPTION
MOTOR: AC series motor with the overheating protection components,
Quick coupling adapter, Automatic positioning coupling and
Adjustable speed switch.
ATTENTION!
• Never operate the motors without pump.
• Never leave the pump unattended.
• Never run dry of the pump.
• The pump should not be immersed deeper into the liquid than
the outlet connection.

3.7. Install the filters in the pump tube bottom when transport the
liquids with impurity or solids. To avoid the blocking, please check
and clean it regularly.
3.8. Make sure the motor under close status before power on.
Never leave the pump unattended and never operate the motors
without pump.
3.9. Do not touch the tube bottom after switching on the electric or
air source. The impeller under high speed rotating may lead to
equipment damage and personal injury.
Make sure the pump tube working under vertical position. Never
upend or lay flat after using. Pay attention to the residual liquids
may lead to injury or cause environmental damage.

8. INSTALLATION
Check if the packing was damaged before opening. Make
sure no missed spare parts.
Safety Check
Make sure that the supply voltage corresponds to the
voltage indicated on the rating plate.
8.1 Motor Installation
8.1.1. Pump tube check: Make sure every joint part no looseness.
The coupling and shaft could be rotated flexible.
8.1.2. Motor Check: Make sure the power cable complete, switch
in good condition. Dry running for several minutes to check if
the motor workable. Do not put hands to the motor output
shaft.
8.1.3. Put the motor coupling is directed at the pump tube. Make
sure the pump tube head insert to the motor head completely.
8.1.4. The motor and pump tube position could be adjusted by
360°. Put the pump tube adjusted to the suitable position and
lock the nut to finish the installation. It is recommended that
the pump exports away from the motor power cable.
7. MOVING AND TRANSPORT
The pump tube and motor adopt the carton box packing. There is
enough protection packing material inside. However, never knock on,
heavy load by the non-normal external force. Please transport and
stacking as per packing indication. Keep drying and anti-corrosion of
the stacking place.
6. OPERATING CONDITIONS
6.1. Environmental Conditions
Electro-Motor operating environment: -25~40캜
6.2. Power Supply
Make sure that the supply voltage corresponds to the voltage
indicated on the rating plate.
ATTENTION!
Power from lines with values outside the indicated limits can
damage the electrical components

9. DAILY USE
Long time continuous running may cause motor overheating, the
overheating protection system will cut the power automatically. The
motor can be restarted work again after cooling down by pressing the
on/off button.
ATTENTION!
The suggested duty cycle is 2 hours. Do not exceed one
hour when the environment temperature more than 30˚C
Please change the electric brush every 250-300hours
8.2 Start
Make sure all the joint parts without leakage. The tube outlet must
be fixed well so to avoid pressure leaking.
8.3. Electrical Connections
• Terminal strip box complete of:
- ON/OFF switch;
- Speed regulating knob switch
- Speed regulating circuit board
• 5M Power cable
ATTENTION!
IT IS THE INSTALLER’S RESPONSIBILITY TO PREFORM THE
ELECTRICAL CONNECTIONS WITH RESPECT FOR THE
APPLICABLE REGULATIONS.

10. NOISE LEVEL
Under normal working conditions the noise emission from all models
does not exceed the valve of 80 db at a distance of 1 meter from
the electric pump.
