screw pumps can work against upto 280 bar pressure,which is no where near to centrifugal pump capacity.
you should note that, screw pumps are used to pump viscous liquids in high flow, high pressure conditions, whereas Centrifugal pumps are used for medium flow,medium pressure conditions.
each pumping application is unique and you should understand the difference between positive displacement pump(screw pump) and centrifugal pump working principles before selecting the pump.
