Twin Screw Pumps
Twin Screw Pumps are self-priming, double ended positive displacement pumps with external timing gears and bearings. Their design provides complete axial balancing of the rotating elements and eliminates all metal-to-metal contact within the pump, making them suitable for dry running. In addition with extremely low NPSH requirement they are ideally suited for decanting applications.
Principle of operation
Twin Screw Pumps consist of one set of shafts-one driving and one driven with two screws mounted and keyed onto each shaft.The liquid entering the pump is divided into two parts each part going to outer end of screws.
As the screws rotate, cavities are formed between the individual screw. These hold a given volume of fluid, moving it axially as the screws rotate. The portion of the fluid that entered the pump and was diverted to the left is then moved by this movement from left to center. The portion of fluid diverted to the right is moved from right to center. At the center the two flow paths rejoin and leave the pump through the discharge flange.
The screws do not mesh with each other. The drive to driven screw is transmitted by means of timing gears. This feature makes them ideally suited for dry running application for short duration. With special profile of screws, pumps have extremely low NPSH requirement making them ideally suited for decanting applications.
