Principle
WINDRYOur Screw Vacuum Pump boasts a sophisticated design with dual paralleled screw rotors and an intricately crafted pump body, forming multiple sealed chambers. These components are precision-engineered to maintain minute clearances that prevent contact and friction. Driven by reverse gears, this ensures flawless, continuous gas transfer from the inlet to the outlet, significantly enhancing overall performance.
Thanks to its friction-free design, the dual rotors and pump body operate without the need for lubrication, ensuring an uncontaminated gas output. This seamless gas transfer, combined with a streamlined pathway, maximizes efficiency. The outlet's strategic position below the screw rotors boosts drainage capabilities and simplifies cleaning. Our innovative design, devoid of intermediate bulkheads, surpasses claw and rotor vacuum pumps in both drainage and exhaust efficiency, while offering remarkable ease of maintenance.
