Liquid carbon dioxide loading pump
Thread Content
My storage tank has a storage pressure of 2.1 MPa. What type of pump should be used to fill carbon dioxide tankers? Centrifugal pump, reciprocating pump, or canned motor pump? Thank you for the guidance!
A shielded pump will suffice; provide the relevant parameters to the supplier.
I checked, and shielded pumps are suitable for toxic, corrosive, and leak-free high-temperature materials. Liquid carbon dioxide is a low-temperature, high-pressure fluid (2.0 MPa), and the information provided by the manufacturers indicates that such pumps can handle high pressures; that’s roughly it.
Use a shielded pump; it’s safe and convenient.
Liquid carbon dioxide has a low temperature and high pressure. Reciprocating pumps and piston pumps are recommended.
Try to use shielded pumps, as they have good sealing properties and it’s easier to implement insulation measures. Reciprocating pumps and plunger pumps can generate high pressures, which is dangerous; it’s also difficult to insulate centrifugal pumps. Our company uses shielded pumps – in my opinion, this is a reasonable choice
Two types of leak-free pumps are available: canned pumps and magnetic drive pumps
Gel-coated twin-screw pump, with no internal leakage, stable flow rate, capable of transporting gas-liquid mixtures
