Vacuum Pump
Roots Vacuum Pump
Roots vacuum pump is equipped with two synchronously rotating rotors, either bi-lobe or multi-lobe, which maintain a specific clearance from each other and from the inner wall of the pump casing. It is classified as a rotary positive displacement vacuum pump, often used as a mechanical booster pump in various applications.
The multi-stage centrifugal blowers are extensively used in various applications that require air delivery. These include providing blast air for smelting furnaces and iron-making furnaces, supporting coal washing jig machines, aiding in mine flotation processes, aerating sewage in wastewater treatment, and gas-making in chemical processing. Roots vacuum pump is also suitable for conveying other special gases.
Features
- Oil-Free Intermediate Sealing: Employs multiple oil-free intermediate sealing methods to ensure a highly clean vacuum environment inside the rotor chamber.
- Guarantees excellent geometric symmetry of the rotors, enhancing performance and manufacturing process.
- Operates with low noise and has a high lifespan.
- The pump's rotors are made from aluminum alloy, which provides rapid heat dissipation, corrosion resistance, and energy efficiency.
- Ensures long-term stable operation without oil leaks utilizing a special shaft sealing method.
- Roots vacuum pump’s design is space-efficient, easy to install, and light, making it ideal for various industrial settings.
