Principle
WINDRYOur Screw Vacuum Pump is a marvel of engineering, featuring dual paralleled screw rotors working in harmony with an intricately crafted pump body. This innovative design forms multiple sealed spaces, ensuring unparalleled performance. The precision-engineered rotors and pump body maintain tiny clearances for a friction-free experience. With the power of reverse gears, the gas is smoothly and continuously transferred from inlet to outlet, setting a new standard in efficiency.
Thanks to its frictionless design, our pump eliminates the necessity for lubrication, thereby ensuring the provision of pristine gas. The uninterrupted gas transfer coupled with an optimized pathway guarantees high efficiency. The strategically positioned outlet, lower than the screw rotors, augments drainage capabilities and simplifies maintenance. The absence of an intermediate bulkhead ensures that our design outperforms traditional claw and rotor vacuum pumps in both drainage and exhaust efficiency, all while being effortlessly maintainable.
