Roots Vacuum Pump
Leynow · Roots Booster Technology
Insufficient vacuum pump pumping speed leads to long waiting times in processes such as adsorption, feeding, and drying, slowing down the efficiency of the entire line.
Poor pump body sealing or wear leads to a decrease in ultimate vacuum degree, affecting the consistency of processes such as coating, distillation, and molding.
Traditional oil-sealed pumps carry the risk of oil backflow, contaminating workpieces, coating chambers, or pharmaceuticals and food, causing quality hazards.
Difficult procurement of filters, valves, and seals; lack of professional maintenance leads to long fault downtime.
Dual rotors rotate synchronously in opposite directions with high volumetric efficiency. The pumping speed in the medium vacuum range is extremely high, shortening pumping time and improving production efficiency.
Non-contact friction between rotors, oil-free operation in the pump chamber; connected in series with a backing pump, it meets clean requirements for coating, pharmaceuticals, electronics, and more.
Various pumping speeds and calibers available. Needs to be connected in series with a backing pump (such as rotary vane pumps, water ring pumps, screw pumps) to form a Roots vacuum unit, covering a wide range of medium-high vacuum requirements.
High protection level motor, Class F insulation, symmetrical structure with low vibration; suitable for 24-hour uninterrupted operation of production lines.
The complete machine has a compact structure and is easy to integrate in series with backing pumps. It can be embedded in various vacuum units or automation equipment, saving installation space.
Gear oil, seals, and valve calibers are matched from the original factory; unit matching and selection are based on backing pump pumping speed, target vacuum degree, and medium working conditions, with maintenance support provided.

The Leynow Roots vacuum pump utilizes two figure-8 shaped rotors rotating synchronously in opposite directions within the pump chamber to draw gas in from the intake port, push it through the space between the rotors and the pump wall, and discharge it from the exhaust port.
A tiny gap is maintained between the rotors and between the rotors and the pump wall, with no contact and no wear, requiring no lubricating oil, and outputting clean vacuum.
Roots pumps are usually used as booster pumps in series with backing pumps (rotary vane pumps, water ring pumps, etc.), which can significantly increase the pumping speed and ultimate vacuum degree; they can also be used for direct atmospheric discharge in rough vacuum working conditions.

Embedded inside the complete machine to provide a stable negative pressure air source.
Usage Limitations: Not suitable for extracting large amounts of dust, highly corrosive, or high-temperature gases; an intake filter must be installed at the front end for dusty working conditions; Roots pumps cannot be operated for a long time with direct atmospheric discharge under high pressure differences (a backing pump is required), and the inlet and outlet must not be completely closed during operation, as this will cause overheating and damage.
Selection Recommendations: For vacuum adsorption and vacuum feeding, prioritize Roots pumps with direct atmospheric discharge; for high-vacuum working conditions such as coating, distillation, and drying, choose Roots vacuum units; when selecting, please provide pumping speed, ultimate vacuum degree, and medium working conditions. It is recommended to reserve a 10-20% performance margin.
Roots pumps are usually used as booster pumps and need to be used with a backing pump (rotary vane pump, water ring pump, screw pump, etc.); if only rough vacuum or vacuum adsorption is required, a direct atmospheric discharge Roots pump can be selected. Selection needs to be calculated based on the target vacuum degree, pumping speed, and medium working conditions; it is recommended to reserve a 10-20% margin.
Standard Roots pumps are not suitable for directly extracting gases containing large amounts of dust, strong corrosiveness, or high temperatures; a filter must be installed at the front end for dusty working conditions; for corrosive gases, anti-corrosion or special material models need to be selected, please consult an engineer.
The Roots pump chamber operates oil-free, but the gearbox needs lubricating oil, please replace it regularly according to the manual; the oil-free pump chamber design provides a clean vacuum and avoids contamination of the process chamber.
Commonly used: intake filter (mandatory for dust prevention), vacuum valves, check valves, buffer tanks, vacuum gauges, etc.; Leynow can supply the complete set.
