Advantages

1. Insensitivity to fluid impurities
2. Insensitivity to fluid viscosity/concentration
3. The possibility of producing high pressures

4. The possibility of transferring a large volume of fluid through the two-way inlet

5. Uniformity of output fluid flow

Disadvantages

1. A large number of bearings

2. A large number of mechanical dams / watertight systems

3. Sensitivity to the alignment of different shells

4. The need to time the screws through timing gears
