Rubber asphalt pump selection
Thread Content
Our company recently installed a new rubber asphalt device. During production, it was found that due to the high viscosity (around 4000), the material discharge was very slow. The discharge pump is now a gear pump. I wonder if the experts have any good solutions.

The viscosity of 4000 is not the highest, sometimes it can reach 5000. The main reason is insufficient suction and the discharging is quite slow.
Can't it be changed to blanking form for feeding?
The discharge pipeline is parallel to the pump inlet, and the distance is about 14 meters.
Oh, there is no suction. What is the normal operating flow rate that our screw pump can guarantee?
Viscosity 5000 (cp cst mm2/s) No doubt it is one of these viscosity units, right?
It is more reasonable for a single screw pump to deliver this viscosity, ps: The original poster~~~can't you increase the temperature a little to reduce the viscosity?
