Principle
WINDRYOur Screw Vacuum Pump is expertly engineered to perfection, featuring dual paralleled screw rotors and an artfully designed pump body. This innovative design creates a series of hermetically sealed spaces. The rotors and pump body are crafted to maintain precise, tiny clearances, ensuring no contact or friction arises. Driven by expertly synchronized reverse gears, the gas is transferred seamlessly and continuously from the inlet to the outlet, delivering performance that is nothing short of extraordinary.
The ingenious frictionless design of our dual rotors and pump body eliminates the need for lubrication, ensuring the delivery of pristine, clean gas. The continuous gas transfer, coupled with a streamlined pathway, delivers superior efficiency. The outlet is strategically positioned lower than the screw rotors, optimizing drainage capabilities and simplifying cleaning. The absence of an intermediate bulkhead allows our design to outshine claw and rotor vacuum pumps in both drainage and exhaust efficiency, while remaining remarkably easy to maintain.
