Principle
WINDRYOur Screw Vacuum Pump is a masterpiece of engineering, featuring dual paralleled screw rotors nestled within a meticulously crafted pump body. This design creates a series of multiple sealed spaces. The rotors and pump body, crafted with precision to maintain minute clearances, operate efficiently without contact or friction. Propelled by reverse gears, the device ensures the continuous and seamless transfer of gas from the inlet to the outlet, delivering unmatched performance and reliability.
Boasting a frictionless architecture, the dual rotors and pump body negate the need for lubrication, ensuring the provision of pristine, clean gas. The continuous gas transfer, coupled with a streamlined pathway, yields superior efficiency. The outlet's strategic placement below the screw rotors enhances drainage capabilities while simplifying cleaning processes. Our innovative design, free from intermediate bulkheads, outshines claw and rotor vacuum pumps in terms of drainage and exhaust efficiency, while offering remarkable ease of maintenance.(Click to contact inquiry)
