Principle
WINDRYOur Screw Vacuum Pump is an epitome of engineering excellence, featuring dual paralleled screw rotors and a precision-crafted pump body. These elements create multiple sealed spaces, with rotors and pump body maintaining minute clearances to ensure no contact or friction. Powered by reverse gears, the gas is seamlessly transported from inlet to outlet, guaranteeing top-tier performance and reliability.
The frictionless design of dual rotors and pump body obviates the need for lubrication, ensuring the supply of clean gas. This seamless gas transfer, coupled with an optimized pathway, delivers exceptional efficiency. The strategically placed outlet, lower than the screw rotors, enhances drainage capabilities while simplifying cleaning processes. Our design, free from an intermediate bulkhead, surpasses traditional claw and rotor vacuum pumps in terms of drainage and exhaust efficiency, offering remarkable ease of maintenance.
