Bung entering screw mount drive mixer for mixing liquids up to 2,000 centipoises in 55 gallon vessels. The collapsible 4″ propellers reduced to 2″ for entry into a drum and opens to 4″ when shaft is turning.
Screw pumps are rotary positive displacement pump in which the flow through the pumping elements is truly axial. Fluid is transferred through successive contact between the housing and the screw flights from one thread to the next. The liquid is carried between the screw threads on one or more rotors. Screw pump has an axial flow pattern and low internal velocities. These pumps transfer fluid by displacing the oil axially through a closely fitted chamber formed between the screw recess and housing wall. These pumps are classified as two different types: the single rotor and multiple rotors. A classic example of screw pumps is the Archimedes screw pump that is used in irrigation and agricultural applications. Screw pumps provide a specific volume with each cycle and can be dependable in metering applications.
A modification of the helical gear pump is the screw pump. Both gear and screw pumps are rotary, positive displacement pump, which comes with two or three screws. It has one or more screws to transfer high or low viscosity fluids along an axis. These pumps have two or more intermeshing screws rotating axially clockwise or counterclockwise. Each screw thread is matched to carry a specific volume of fluid. Like gear pumps, screw pumps may include a stationary screw with a rotating screw or screws. Fluid is transferred through successive contact between the housing and the screw flights from one thread to the next. It provides a specific volume with each cycle and can be dependable in metering applications.
