Consultation on the selection of high-viscosity pumps
Thread Content
As shown in the figure below, high-viscosity heavy oil (similar to asphalt) contains solid particles, and a transport pressure of 1 MPa is sufficient. What kind of pump do you all use for pumping?
Help, this is the condition at 10 degrees Celsius
A screw pump made of high-viscosity asphalt can be used.
Thank you. Can high-viscosity asphalt screw pumps pump fluids containing solid particles? I really don’t know anything about this. If you know any manufacturers in this field, please let me know. Thank you very much
For details about Botou Honghai Pump Industry, you can consult the manufacturer.
If high flow rates are required, centrifugal pumps can also be used; for example, centrifugal pumps are employed in the atmospheric and vacuum distillation units as well as in catalytic units in oil refineries to handle materials such as asphalt and slurry.
The level of fluidity shown by the original poster is something that centrifugal pumps definitely cannot handle. My suggestion: two options – 1. Twin-screw pump with synchronizing gear, 2. Single-screw pump
Regardless of whether it’s possible to transfer the material or not, since the material contains solid particles, using a centrifugal pump isn’t very suitable.
Some materials have very high viscosity at low temperatures and are in a paste-like state, but they exhibit better fluidity at high temperatures. Have you heard of the slurry pumps used in the catalytic units of refineries? For applications involving catalyst-containing solid particles with poor flow properties at low temperatures, centrifugal pumps are the most suitable choice, although higher requirements are placed on the material used. Screw pumps are a good choice; they are suitable for transporting both crude oil and feedstock oil. What I mean is that for the materials shown by the original poster, a centrifugal pump can be used if the temperature is relatively high.
Mm. If the solid particle content is too high, a screw pump is a better choice.
Suction and pumping are two different things. This material has very poor flowability; it cannot be drawn up using a suction method. It is best to use a filling-type feeding method; screw pumps/hose pumps are good choices.
