chemical processing of coal

 — Coal pitch, coal tar transportation.


Twin screw pump Application in chemical processing of coal

Twin-screw pump can be used for coal pitch and coal tar transportation. The twin-screw pump is also the most ideal pump for conveying coal-water slurry and has a longer service life than the single-screw pump. It can efficiently transport various high and low-viscosity media, especially the media that do not allow stirring and the media that are easy to vaporize. The twin-screw pump can also convey the medium smoothly and without pulsation under the condition of high temperature and high pressure.

Why choose our twin screw pump

Wide range of conveying viscosity

It can convey extremely high-viscosity chemical materials and is efficient and energy-saving, with low failure rate; and when conveying low-viscosity media, it has outstanding advantages such as smooth conveying, no stirring and no pulsation.

Frequency conversion control-Energy saving

It can realize flow regulation under constant pressure, suitable for frequency conversion control, and the effect of energy saving and consumption reduction is remarkable.

Low noise and long life

In the structure, a certain gap is maintained between the helix and the helix, and between the helix and the bushing, so there is no direct mechanical wear. If the external structure is selected, the transmission system is independently lubricated and does not contact the conveyed medium.

Suitable for high temperature, corrosion, abrasion

It can be designed as a heat preservation and sealed cooling system, suitable for medium transportation in high temperature, corrosion, abrasion and other occasions
