LCO2 Liquid Carbon Dioxide Pump for Transfer and Filling CO2

The Liquid carbon dioxide is a liquid carbon dioxide booster and can effectively withstand low temperatures as low as -50℃. Therefore, it is suitable to transfer and fill cryogenic liquefied carbon dioxide that comes from Dewar vessels, ISO tanks or cryogenic storage tanks normally. To be specific, the carbon dioxide pump is capable of suctioning low-pressure liquified carbon dioxide and then output high pressure liquid carbon dioxide of 800bar maximum, so as to ensures that carbon dioxide remains in the liquid phase during the transfer and filling process. The liquid carbon dioxide pump takes compressed air as its driving power, and carbon dioxide discharge pressure is directly proportional to drive air pressure.So if your adjust the driving air pressure, the liquid Co2 pump discharge pressure will be changed accordingly.

Liquid Carbon Dioxide Pump Benefits

  • Ideally booster, transfer and fill liquid carbon dioxide
  • Oil-free compression optional for output food-grade carbon dioxide
  • Cryogenic seals and stainless-steel wetted parts for cold liquid CO2
  • Multiple models to meet your dual demands on pressure and flow
  • Output pressure up to 80MPa and pressure adjustable
  • Automatic stop at your set pressure prevents overpressure

Liquid CO2 Pump Applications

  1. Used as carbon dioxide extraction pump for CO2 supercritical extraction.
  2. Served as carbon dioxide transfer injection pump for CO2 foaming.
  3. Acts as a Co2 extinguisher refilling equipment.
  4. Charge carbon dioxide propellant gas into CO2 cartridges.
  5. Maintain and supplement pressure for liquid carbon dioxide centralized supply system or pipeline.

How to Choose Carbon Dioxide Pumps

If your CO2 sources from cryogenic storage tanks, please choose liquid CO2 pump. If your CO2 comes from steel cylinders that store gas-liquid mixture Co2. While liquid CO2 pump can only suction liquid CO2, which means the CO2 gas in steel cylinders will be wasted. Therefore, multiphase carbon dioxide pump is more suitable for you, because it can handle both liquid and gaseous carbon dioxide.

Carbon Dioxide Pump Station

A carbon dioxide pump station

In order to facilitate user operation, we have created the carbon dioxide pump station. It is a self-contained carbon dioxide compressor that intergrades carbon dioxide booster pump, air regulator, pressure gauges, manual valves, isolation valve, threaded fittings into a robust skid, thus easy to move and convenient to operate.
