Cryogenic Liquid CO2 Cylinder Filling Pump for Cold Storage
Products Description
Our liquid co2 pump optimizes flow channel based on cryogenic fluid mechanics to reduce medium vaporization risk. Separated design between power end and cryogenic medium end prevents cold transfer damage to motor and transmission parts. Medium wetted parts adopt 304 /316L stainless steel with excellent low temperature and corrosion resistance. Single unit or multiple parallel installation is available to meet large flow continuous transfer requirement according to working conditions. Pump head can withstand -40℃ cryogenic working condition with wide output pressure range, serving as core fluid equipment for liquid carbon dioxide transfer and pressurization.

Common Troubles & Solutions about co2 pump
| Trouble | Reason | Solution |
|---|---|---|
| No liquid output | Insufficient inlet pressure, CO₂ vaporization gas blockage |
Increase the static pressure of the storage tank, check the cold insulation of the inlet pipeline, and check the inlet temperature |
| Low flow rate | The inlet and outlet valves are clogged and the seals are leaking. |
Check the valve core and replace the aging seals |
| High noise | Cavitation, loose fixed base |
Optimize entrance anti-cavitation and tighten base bolts |
| Pump frequent shutdown | Overload, pressure protection triggered |
Check the outlet pipeline for blockage and pressure setting value |
| Seal leakage | Seal aging, medium containing impurities |
Replace cryogenic seal, inlet filter |
