Introduction to Dry Screw Pumps
Dry screw pumps are a type of positive displacement pump that operate without the need for lubricating fluids in the compression chamber. This design offers several advantages, such as clean pumping, low maintenance, and high reliability. They are widely used in various industries, including semiconductor manufacturing, chemical processing, food and beverage, and vacuum coating. Dry screw pumps work by the meshing of two or more screw rotors, which create a series of sealed chambers that move the gas from the inlet to the outlet. As the rotors rotate, the volume of the chambers decreases, compressing the gas and discharging it at a higher pressure.
