What kind of pump is suitable for transporting coal tar?
Thread Content
Hello everyone, based on the parameters specified below, which pump would be the best choice for transportation? Are there any other things I need to pay special attention to regarding shaft seals? Installation location: Inside. Medium name: Coal tar transfer pump. Medium temperature: approx. 110 °C. Solid content: 3%. pH value: neutral. Dynamic viscosity: approx. 1230 kg/m3. Medium flow rate: 10 m3/h. Inlet pressure: free flow into the pump. Outlet pressure:
So, according to what you said, I just need to choose a centrifugal pump?
If a centrifugal pump is used, do the bearings not require special attention? Can a single-screw pump be used for transportation in such cases? Thank you!
Solid content: 3%. A regular centrifugal pump probably won’t work; the mechanical seal likely won’t be able to handle it! ! ! It might be more appropriate to consider a slurry pump!
A tar pump can be a centrifugal oil pump; ideally, a gear oil pump can also be used, as it has a longer service life.
Centrifugal pumps or piston pumps are both acceptable. . . . . . . . .
I’m very glad to have everyone’s support. I hope to gain more insights from real-world usage experiences. Thank you again!

Reply to 1# silence418: Gear pumps are quite good
We have used both plunger pumps and centrifugal pumps; personally, I think centrifugal pumps are quite good. Higher requirements are placed on the mechanical seals, so choosing a quality one should resolve any issues.
We use centrifugal pumps on site, and there’s no problem with that. The mechanical seals have been properly selected, so everything is fine. It’s also recommended that you put your tar through a super centrifuge to remove the residues and moisture from it; this will be very beneficial for your distillation process. Otherwise, the lifespan of your distillation trays won’t be long
