Screw pump - Wikipedia
A screw pump, also known as a water screw, is a positive-displacement (PD) pump that use one or several screws to move fluids or solids along the screw(s) axis. In its simplest form (the Archimedes screw pump), a single screw rotates in a cylindrical cavity, thereby moving the …
Screw Pump Basics - Empowering Pumps and Equipment
A screw pump is a type of positive displacement pump that uses two or more screws that intermesh to pressurize fluids and move them in a system. The screws take in fluid then push it out from the other side while increasing its pressure. Types of the Screw Pumps
What is a Screw Pump? | Types of Screw Pumps | PowerZone
Screw Pumps - An Overview. A screw pump is a type of rotary pump which is equipped with screws that mesh together and rotate within a cylindrical cavity or liner. The fluid enters from the suction side of the pump and moves linearly along these intermeshing screws to the discharge side of the pump.

What is Screw Pump and How it Works | marinersgalaxy
Screw pump has a structure same like a screw. I mean the whole construction of the spindle is like a archimedes screw and this spindle is responsible for the pumping action of the pump. It has been observed over the years that this pump requires least maintenances and therefore, is a potential device for increasing the pressure.
