Introduction to the Features of Roots Vacuum Pumps


Release date:

2021-04-12

The entire line of Roots vacuum pumps is standardly equipped with high-strength ductile iron rotors, featuring a tensile strength of 400 MPa and an elongation at break of 15%. The components of the Roots vacuum pump are precisely machined using machining centers, with strict control over the clearances between rotors and between rotors and the pump housing, ensuring stable operation even when these clearances are less than 0.05 millimeters.

  3. The composite sealing structure technology completely solves the issues of emulsification and leakage of pump oil in vacuum pumps, making them more stable and reliable.

  4. The spiral jacket cooling method, with its excellent heat exchange efficiency, fully ensures the low-temperature lubrication performance of the lubricating oil, thereby extending the service life of gears, bearings, and mechanical seals.

  5. Roots vacuum pump Equipped with precision gears (grade 5 accuracy) and connected via a precision coupling, this ensures smooth pump operation and accurate power transmission, resulting in extremely low operating noise.

  6. The Roots vacuum pump is equipped with high-strength, high-lateral-load-resistant precision bearings (imported SKF) and features splash lubrication, which can significantly extend the pump’s service life.

  7. An internal bypass valve is installed, allowing the Roots vacuum pump and the forepump to be started almost simultaneously under atmospheric conditions, thereby shortening the pumping time.

  8. Self-manufactured and directly sold by the manufacturer; recognized as a high-tech enterprise and a science-and-technology enterprise; has obtained ISO9001 quality management system certification.

  9. Our company’s after-sales service engineers travel across the country, always on standby to provide on-site guidance for installation and commissioning work. Roots vacuum pump Let users shop without worry.
