Principle
WINDRYOur Screw Vacuum Pump is a marvel of modern engineering, featuring dual paralleled screw rotors within a carefully crafted pump body. These components create numerous sealed chambers, working in harmony with precision gaps that prevent friction and contact. Driven by specially designed reverse gears, this system expertly channels gas from the inlet to the outlet, delivering unwavering, high-performance vacuum capabilities.
Boasting a frictionless design, our dual rotors and pump body require no lubrication, ensuring the purity of the gas processed. The streamlined gas transfer pathway maximizes efficiency, while the strategically positioned outlet simplifies drainage and cleaning. Without an intermediate bulkhead, our pump outperforms traditional claw and rotor designs in both drainage and exhaust proficiency, all while being remarkably easy to maintain.(Click on inquiry)
