FTI Principle and precautions of barrel pump

A barrel pump is a barreled liquid transfer tool used to pump various clean, corrosive and non-corrosive

 liquids from a barrel into other containers.

Principle: The motor (electric or pneumatic) at the top of the barrel pump rotates the pump shaft, which 

in turn causes the impeller at the bottom of the pump shaft to spin at high speed. This generates centrifugal 

force, which transports the liquid around the impeller toward the pump outlet in the direction indicated by the arrow in the diagram.

Structure: A barrel pump primarily consists of the following components: motor, pump head, pump tubing, inner tube, shaft, and impeller.

Usage and Installation Precautions:

1. Avoid running the pump dry. Once the barrel has been completely pumped, stop the pump as soon as possible.

2. Ensure the motor and pump are properly connected, as failure to do so may damage the coupling. After installing 

the motor, tighten the two handle set screws. Minimize repeated installation and disassembly to extend the service life 

of the coupling, coupling spring, pump head, and bearings. Ideally, the pump outlet should be 180 degrees from the 

motor handle and away from power cords.

3. For the PT series, carefully check that the pump tubing is tightened to the pump head during operation. Loose tubing

 can cause the tubing to move downward, resulting in the impeller becoming stuck and the pump malfunctioning.

4. If the pump has no flow or unstable flow, stop the pump immediately and check that the pump shaft can rotate 

freely. Continuing to operate the electric motor when the pump is stuck can cause overload and damage.

5. When using the variable-speed motors provided with the PT and TB series, the higher the viscosity of the medium,

 the lower the speed should be. For high-viscosity media, excessive motor speeds can easily cause overheating and

 damage. Please refer to the viscosity range and read the accompanying operating manual. If the motor stops midway 

during operation and the switch fails, do not worry. This is not a sign of motor damage. Rather, it is caused by excessive

 operation and excessive temperature, which has caused the internal protection switch to cut off the power supply. 

Allow 5-10 minutes for the motor to cool before resuming operation. It is recommended to rest for 5 minutes after 

every 20 minutes of operation before resuming operation.

6. If the liquid frequently contains large particles or fibers, install a filter at the pump's bottom inlet.

7. Before pumping corrosive liquids, ensure that the liquid will not corrode the pump tubing. Plastic pump tubing 

(PP and PTFE) and standard electric motors are strictly prohibited from use in explosion-proof environments.

8. When using a barrel pump in an explosion-proof environment, always use stainless steel tubing and equip it with 

an imported US pneumatic motor or explosion-proof motor. It is best to ground the pump tubing to prevent static 

electricity and sparks.

9. Always keep the motor upright. Do not invert the pump tubing and motor to prevent liquid from flowing back into 

the motor, corroding and damaging it.
