Principle
WINDRYOur Screw Vacuum Pump is an engineering marvel, meticulously crafted with dual paralleled screw rotors and a precisely designed pump body. This combination creates multiple sealed spaces, where the rotors and pump body maintain minute clearances, ensuring no contact and friction. Driven by reverse gears, gas is transferred seamlessly and continuously from inlet to outlet, guaranteeing outstanding performance and reliability.
The advanced 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, results in exceptional efficiency. Our outlet, strategically positioned lower than the screw rotors, enhances drainage capability and simplifies cleaning. With no intermediate bulkhead, this design surpasses claw and rotor vacuum pumps, offering superior drainage and exhaust efficiency while being remarkably easy to maintain.(Click to contact inquiry)
