6. Gear pump
The smaller the pseudoplasticity index n, the more sensitive the screw flow Q is to pressure variations ΔP.

screw depth in the pumping zone.
For most polymers, n is of the order of 0.3, so that a 1.5% variation in pressure results in a 4.5% variation in flow.
A gear pump is capable of a more stable flow than a screw: this is why its...
