What are the differences between screw pumps and multistage pumps?
The efficiency depends on the pump stage (pressure)
Very high efficiency, 0.6-0.85, lower motor power, lower energy consumption 20% -30%
3. Screw pump maintenance cycle is relatively long.
2. The appearance of the volume of the case, the screw pump displacement is less than the centrifugal pump.
Screw pump is a positive displacement pump, centrifugal pump is centrifugal, the working principle is not the same.
