Principle
WINDRYOur Screw Vacuum Pump is expertly engineered with dual paralleled screw rotors, complemented by a meticulously crafted pump body, forming multiple sealed spaces. The rotors and pump body are precisely designed to maintain minuscule clearances, ensuring no contact and zero friction. This innovative approach, driven by reverse gears, facilitates the seamless and continuous transfer of gas from the inlet to the outlet, delivering superior and consistent performance.
With its frictionless architecture, the dual rotors and pump body completely eliminate the need for lubrication, allowing for the delivery of pure, clean gas. The continuous gas transfer, coupled with an optimized pathway, ensures exceptional efficiency. The outlet, strategically positioned lower than the screw rotors, boosts drainage capability and simplifies cleaning. With no intermediate bulkhead in its design, our pump outperforms both claw and rotor vacuum pumps in drainage and exhaust efficiency, while being remarkably easy to maintain.
