01
All models come standard with QT500 high-strength ductile iron rotors, with a tensile strength of 500MPa and an elongation of 15%.
paragraph
02
Components are precision-machined using imported machining centers, with strict control over the flow between rotors and between the rotor and pump body.
paragraph
03
Composite sealing structure technology completely solves the problems of emulsification and leakage of vacuum pump oil.
paragraph
04
Spiral jacket cooling method, whose excellent heat exchange efficiency fully guarantees the low-temperature lubricity of the lubricating oil.
paragraph
05
Precision gear transmission (grade 5 precision) and precision coupling connection ensure smooth pump operation.
paragraph
06
Selected high-strength, high-lateral-force-resistance precision bearings (SKF/NSK).
paragraph
07
Internal bypass valve allows the Roots vacuum pump and backing vacuum pump to start almost simultaneously under atmospheric conditions.
paragraph
08
