Principle
WINDRYOur Screw Vacuum Pump exemplifies precision engineering with its dual paralleled screw rotors and specially designed pump body. This design forms multiple sealed spaces, crafted to operate with precise clearances, ensuring no contact and no friction. The reverse gear-driven mechanism allows for uninterrupted gas transfer from inlet to outlet, delivering exceptional performance and reliability.
Thanks to its innovative frictionless design, the dual rotors and pump body obviate the need for lubrication, maintaining gas purity. The seamless gas transfer, complemented by an optimized pathway, enhances efficiency. Positioned below the screw rotors, the outlet ensures superior drainage and eases cleaning. Our design, free from intermediate bulkheads, outperforms claw and rotor vacuum pumps in both drainage and exhaust efficiency while being incredibly user-friendly for maintenance.(Click on inquiry)
