What pump should be used for coal tar as fuel?
Thread Content
Our company has newly installed a chemical processing unit that uses coal tar as fuel; we would appreciate everyone’s expert opinions on which type of pump would be suitable. Parameters of the coal tar pump used in the feeding device:Serial number | Item | Unit | Value | Remarks
1 | Medium | Coal tar | — | —
2 | Flow rate | m3/h | 2–3 | —
3 | Pressure | Mpa | 1.2–1.5 | —
4 | Density | kg/m3 | 1100–1220 | —
5 | Temperature | °C | 50–70 | —
6 | Viscosity | cp | 50–100 | —
Parameters of the coal tar unloading pump:
Serial number | Item | Unit | Value | Remarks
1 | Medium | Coal tar | — | —
2 | Flow rate | m3/h | 30 | —
3 | Pressure | Mpa | 0.4–0.5 | —
4 | Density | kg/m3 | 1100–1220 | —
5 | Temperature | °C | 50–70 | —
6 | Viscosity | cp | 50–100 | —
I personally recommend using gear pumps (arc gear pumps). The specific models are as follows: 1: YCB2.5/1.6-1 – flow rate: 2.5; pressure: 1.6; motor power: 4KW, grade 4. 2: YCB30/0.6-1 – flow rate: 30; pressure: 0.6; motor power: 11KW, grade 6. A packing seal will suffice. Feel free to contact me if you have any specific questions
Gear pumps will work, as mentioned above; however, might the flow rate be too low? It should at least be higher than the flow rate required by the process. Screw pumps are also an option: 1, 2.1-18; 2, 4.2-56
For the first coal tar pump, where high pressure is required, a twin-screw pump is more suitable; a gear pump can also be used. A gear pump is more suitable for the second unloading pump. American Viking Wicken gear pumps have achieved many successes in the coal tar sector. Please contact for assistance.
