The three screw pump, also known as the triple screw pumps, is typically used for small applications, such as lubrication systems. One of the screws is driven from the power source, which then rotates the other two screws around it, without the use of timing gears.In the case of a triple screw pump, shaft seals are only needed on the driving rotor. The other rotors, including their bearings, are encased inside the pumping chamber and do not protrude out.Triple screw pump can transfer lubricating oil, engine oil, crude oil, palm oil, fuel oil, heavy oil and some other liquids like oil.
