For high viscosity asphalt media, should we choose a screw pump or a gear pump?

1. Screw pumps have the following characteristics:

1) High energy-saving efficiency.

2) It has the characteristics of small pressure pulsation and stable conveying flow.

3) Low noise (about 40 decibels).

4) It works smoothly and reliably, allowing high speed.

5) Long service life.

6) Strong self-priming ability and other characteristics

2. Gear pumps have the following characteristics:

1) The gear pump can run dryly, especially in the case of sudden material failure or operation error, which prevents the damage of the pump and ensures safe operation.

2) The gear pump is small in size, which is one-third of the installation area of the single screw pump, which reduces the scope and cost of civil engineering.

3) The gear pump can be repaired online without disassembling the pipeline, which is convenient and fast, and reduces the downtime.

4) The non-extrusion working principle of the gear pump, the adjustable design of the shell, prolongs the use time, reduces the number of maintenance, and saves the cost of spare parts.

5) allow high pressure conveying (the highest screw pump in china can only reach 6.3mpa)
