    Tips: What is Difference Between Gear Pump and Screw Pump?

    The main difference between gear pumps and screw pumps is the way they move fluid through the pump. In a gear pump, the fluid is moved by the rotation of two or more gears, which mesh together and create a pumping action. In a screw pump, the fluid is moved by the rotation of a screw-like rotor within a stator, which creates a series of sealed chambers that move the fluid through the pump.

    Another difference between the two types of pumps is their efficiency and pressure capabilities. Generally speaking, screw pumps are more efficient than gear pumps, especially at higher pressures. Screw pumps are also better at handling viscous fluids, while gear pumps are better suited for lower viscosity fluids.
