Working Principle
The screw vacuum pump is ingeniously designed with a pair of interlocking screws that rotate synchronously in reverse at high speeds within the pump casing. This precise mechanism creates a powerful suction and exhaust function. Each screw is meticulously balanced and supported by robust bearings, ensuring flawless alignment and efficient performance. Thanks to the precise clearances between the screws, the pump operates friction-free, resulting in remarkably smooth operation and minimal noise. It excels in applications that require the removal of large amounts of water vapor and small quantities of dust-laden gases. This advanced pump boasts exceptional vacuum levels, reduced power consumption, and energy-efficient operation, all while being maintenance-free. Its superior performance makes it an ideal choice for industries such as pharmaceuticals, chemicals, semiconductors, food packaging, and any sector demanding a pristine vacuum environment.
