Screw pumps have a wide range of applications, such as in the petrochemical, mining, and manufacturing industries, and can transport various fluids such as oils and polymer materials. Many lubrication and hydraulic equipment use screw pumps to supply oil to them. Screw pumps have a wide range of pressure and flow, as well as a wide range of types and viscosity of liquids to be transported. Due to the low inertia force of the rotating components inside the pump, high rotational speeds can be used. Good suction performance, self suction ability, uniform flow rate, low continuous vibration, low noise, and other advantages.
