Seeking help in selecting a high-pressure feed pump! ! !
Thread Content
The slurry material (with a solid content of less than 5 wt%) needs to be pressurized to 20–30 MPa before feeding. Which type of pump is more suitable for use in small as well as large-scale installations? Also, are there any pumps that can be used for feeding liquid-solid mixtures at 200–300°C with a solid content of less than 5 wt.-%?
If solids are present, centrifugal pumps are generally not a viable option. Moreover, the required pressure is quite high; a screw pump would be an appropriate choice (I haven’t worked with them before, but they should work). For media at 200–300°C, it’s also possible to implement a suitable flushing scheme
I guess a piston pump might be the better choice; I don’t know much about positive displacement pumps
Reciprocating pumps should be able to do it, but the temperature needs to be a bit higher; you can consult the manufacturer for details
With such high pressure, it is difficult for screw pumps to achieve it if the viscosity of the material is low; consult the plunger pump manufacturers
I don’t know what the traffic volume is! You can refer to slurry pumps (plunger pumps), whose operating conditions are even more severe than yours.
I also want to know the answer to this question. Please, experts, answer it so that I can learn from it with an open mind*
What’s the traffic volume? If the flow rate is not high, it is recommended to use a reciprocating pump.
Do you have the contact information for this manufacturer?
The flow rate is not high, ranging from 10 mL to 200 mL/min – won’t the reciprocating pump get clogged? Have you used it before, or do you have any information on the manufacturers involved?
