Principle
WINDRYOur Screw Vacuum Pump is a masterpiece of precision engineering, featuring dual paralleled screw rotors and a meticulously crafted pump body, creating multiple sealed spaces that ensure optimal performance. Designed with minute clearances between rotors and pump body, this advanced system ensures no contact or friction. Driven by reverse gears, it guarantees a seamless, continuous transfer of gas from inlet to outlet, setting new standards in vacuum technology.
Innovatively frictionless, the dual rotors and pump body negate the need for lubrication, delivering pristine gas quality. This efficient design, with a streamlined pathway, maximizes performance. Strategically positioned, the outlet enhances drainage and simplifies maintenance. Our design, free of intermediate bulkhead, outperforms traditional claw and rotor vacuum pumps, offering superior drainage and exhaust capabilities, all while being exceptionally easy to maintain.(Click to contact inquiry)
