Chemical pumps
Thread Content
Our company’s projects require several circulation pumps for external circulation around the reaction vessels. The medium contains bubbles. Operating temperature: -60°C, flow rate: 2 m3/h, head: 15 m. The preferred material for the flow-through component is 316L; the pump head can withstand a pressure of 0.6 MPa. Has anyone used a pump similar to this for such applications? Are there any suitable manufacturers you can recommend? Thank you! !
It is recommended to look into \"reciprocating cryogenic liquid pumps\"; these pumps offer high pressure but an appropriate flow rate, and can operate at temperatures low enough to handle liquids such as oxygen, nitrogen, and argon as the working medium. Search for Duoduo online. For reference.
Acyl fluoride, and then there are oxygen bubbles inside
Yes, one issue is low temperature, and the other is the presence of bubbles; many manufacturers are unable to handle this
I asked a few companies, and they said they can’t produce media with bubbles. .
Saturated liquid is inevitable; it should be possible to handle this by raising the liquid level and pumping from the bottom. Most have return air ducts. Should a supercooler or similar device be considered before the pump to reduce the amount of vaporization? For reference.
Can it increase the pressure above the medium in the storage tank to prevent all oxygen from vaporizing?
Is it possible, through processing, to separate the bubbles from the liquid first, ensuring that the liquid fed into the pump contains no bubbles? If the fluid viscosity is too high, gas-liquid separation is not easy to achieve. As for pump types, centrifugal pumps need not be considered.
