Trained person are required to transport the pump
The complete set pump can be handled by forklift or crane
4.1 Safety instructions
• Be careful to drop or unfixed parts that can cause severe abrasions.
• Do not remove the inlet and outlet end caps of the pump until the piping is connected.
4.2 Forklift transportation instructions
• Pay attention to parts falling, which may cause serious injury and bruises on your hands and feet.
To prevent rollover during transportation, use a conveyor belt or bolt to fix the plate

4.3 Crane transportation instructions
• "Warning", pay attention to parts falling, which may cause serious injury, bruises and even death.
To prevent falling during transportation, use a suitable lifting tool.
• Please make sure that the crane and the rope are strong enough.
• Make sure nobody stay under pump
5 Store
5.1 Storage environment of the pump
• The pump shall be stored according to the following procedures:
1. Drain the pump medium and keep it dry. Store it in a dry environment.
2. Storage temperature should not be too high or too low,
suitable for storing temperature is 20 ℃to 25 ℃(rnormal temperature).
3. The storage environment shall be ventilated and dust-free.
4. All parts of the pump are required to rotate regularly (three months)
5.3 Restart to use
• After storage, please check the mechanical seal before restart to use.
6 Installation and use procedures
6.1 Installation safety instructions
• Make sure that each part is fixed during installation,
falling parts may cause damage to the pump, as well as injury to personnel.
• please wear labor protection shoes when installing.
• Fix bolt according to the specified torque, please check 11.1 《Bolt Fixed Torque Table》
• Use a torque wrench
6.2 Precautions for pump installation
• Confirm the installation environment of the pump,
explosion-proof pump should be used in the explosion-proof environment.
• The environment must be dust-free.
• Working environment temperature at-20 ℃to 40 ℃.
•The installation platform must be strong enough to support the whole pump.
• The installation platform must be horizontal.
•Sufficient maintenance space must be guaranteed.
• Ensure the air circulation of the installation environment and promote the heat dissipation of the motor.

6.3 Reduce noise and vibration
6.3.1 Main measures
• Operate in optimum working conditions to avoid cavitation.
• Avoid resonance of inlet and outlet pipeline.
• Fix inlet and outlet pipelines.
6.3.2 Auxiliary measures
• Isolation measures can be used to isolate noise, such as sound insulation coverage, space isolation, etc.
6.4 Installation method
• Use base mounting to install the pump ,and the pump is mounted on a fixed mounting platform.
• Use base mounting to install (with adjustable support foot), the height of the support foot can be adjusted
freely to ensure the stable installation of the pump.
6.5 Pipeline installation
• Reduce pipe resistance as much as possible and
avoid to use unnecessary elbows and valves.
• When designing piping connection, try to avoid
causing pressure loss and avoid cavitation caused by
inhalation end
• The inlet and outlet control valves should be as close
as possible to the inlet and outlet end.
• Inhalation end pipeline should be as short as
possible
• The inlet end pipeline should be installed horizontally
to reduce the possibility of residual air in the pipeline.
• Design pipeline reasonably according to pressure,
temperature and medium characteristics.
• Avoid stress from pipes to pumps (pipes must be
supported independently)

6.6 Electric Power Installation
• "Warning". Attention should be paid to using ground wire to connect pumps to eliminate static electricity
• Electrical connections need to be completed by qualified electrical engineers
1. Check motor nameplate to confirm rated power, rated voltage and wiring mode.
2. Follow the wiring diagram in the Motor junction box to connect the electricity.
3. Click start motor with less than 1 second and check motor rotation direction.
4.Rewiring is required if the rotation direction is wrong.
Attached image, correct rotation direction of motor
6.7 water flushing pipeline connection (double machine seal)
• pumps with double mechanical seals must be connected to water flushing lines and supplied with cooling
water.
