Product Description
Overview
Roots pump is a vacuum pump without internal compression, which is a vacuum pump that relies on a pair of "8" -shaped rotor in the pump cavity to move the gas by synchronous and reverse rotation.Usually, the pumping rate is large and the configuration motor power is small, so the pre-pumping of the pre-stage pump is required. After the pre-stage pump is pumped to the specified vacuum degree, the roots vacuum pump is started to improve the pumping speed and vacuum degree. Its structure and working principle are similar to the Roots blower, and the suction port is connected with the main pump of the vacuum container or vacuum system when it works. There is no contact between the rotor and the rotor, and between the rotor and the pump housing
Features
● No friction between moving parts inside the pump, no need for lubrication, and no oil in the pump chamber, allowing for a clean vacuum.
● Two-lobe cycloid involute design, with high-precision machining ensuring smooth and quiet operation.
● The gas inside the pump chamber flows vertically, aiding in the discharge of dust and condensate from the extracted gas.
● High-strength rotors with perfect symmetry and precise dynamic balancing ensure stable and reliable operation.
● Equipped with high-precision gears and imported bearings, resulting in low vibration and noise.
● An innovative three-dimensional water cooling jacket design effectively cools the pump body, significantly extending the pump's lifespan.
● Can be combined with liquid ring vacuum pumps, rotary vane vacuum pumps, dry vacuum pumps, and others to form Roots vacuum pump systems.
Typical Applications
Roots pumps are widely used in vacuum casting, vacuum smelting, vacuum degassing, vacuum coating industry and vacuum distillation, vacuum drying and other application scenarios in the chemical and pharmaceutical industry that require high vacuum working conditions.
