Principle
WINDRYOur Screw Vacuum Pump is a pinnacle of innovation, featuring dual paralleled screw rotors encased in an intricately designed pump body. This sophisticated design forms multiple sealed spaces, where the rotors and pump body are crafted to maintain precision clearances (ensuring no contact, no friction). Powered by reverse gears, the seamless transfer of gas from the inlet to outlet results in outstanding performance.
Boasting a frictionless design, the dual rotors and pump body operate without lubrication, ensuring the delivery of uncontaminated gas. With a continuous gas transfer system and a streamlined pathway, efficiency is greatly enhanced. The strategic position of the outlet below the screw rotors optimizes drainage capabilities and simplifies cleaning. The absence of an intermediate bulkhead elevates our design above traditional claw and rotor vacuum pumps in terms of drainage and exhaust efficiency, while maintaining exceptional ease of maintenance.(Click to contact inquiry)
