Principle
WINDRYExpertly engineered with precision, our Screw Vacuum Pump incorporates dual paralleled screw rotors alongside a meticulously crafted pump body, which together form multiple sealed spaces. The perfectly calibrated rotors and pump body ensure minimal clearances, allowing for a frictionless operation with no contact. Driven by innovative reverse gears, the gas is transported seamlessly and continuously from the inlet to the outlet, achieving unparalleled high performance.
Thanks to its frictionless design, the pump's dual rotors and body operate without lubrication, delivering incredibly clean gas. The continuous transfer of gas together with an optimized pathway results in exceptional efficiency. Strategically, the outlet is designed lower than the screw rotors to enhance drainage capabilities and simplify cleaning. Our design, which lacks an intermediate bulkhead, surpasses conventional claw and rotor vacuum pumps in both drainage and exhaust efficiency, making maintenance remarkably straightforward and efficient.
