Product Description

The E2M series rotary vane pumps are oil - sealed vacuum pumps, renowned for their high - vacuum performance, high pumping speed, low - noise operation, and the ability to handle water vapor .

The detailed introduction is as follows:
- Structural Design: The direct - drive rotary vane pumps feature a compact and vibration - free design. They are equipped with a hand - proof fan and a coupling housing to ensure the safety of operators.
- Working Principle: Through the rotation of the eccentric rotor and rotary vanes in the pump cavity, a variable - volume space is formed, which sucks in gas from the inlet, compresses it, and then discharges it from the outlet.
- Operating Conditions: The working temperature range is generally 12ºC - 40ºC. It is suitable for non - flammable gases and vapors, and should not be used to extract flammable, explosive or corrosive gases. It needs to be equipped with the specified lubricating oil, such as Ultragrade series lubricating oil, and maintain the appropriate oil level.
- Functional Advantages : It has an advanced oil - pressure circuit, which can provide effective lubrication even under high gas loads. When the pump is turned off, the spring - type distribution valve can prevent the back - suction of oil and air, protecting the pump body. The gas ballast control can handle high water vapor loads. The industrial - grade roller bearings installed on the drive shaft improve the reliability and extend the service life. The full - height oil viewing window facilitates the inspection of the oil level. Larger models are equipped with an oil filter status indicator for easy replacement of the oil filter.

The E2M rotary vane pumps are widely used in various fields such as semiconductors, metallurgy, and pharmaceuticals. Here is a detailed introduction to their application areas:
- Semiconductor Manufacturing: In the process of semiconductor chip production, processes like lithography, etching, and thin-film deposition all require a high-vacuum environment. The E2M rotary vane pumps can provide stable vacuum support, ensuring the smooth progress of these processes and helping to improve the precision and quality of chip manufacturing.
- Vacuum Metallurgy: They are used in processes such as vacuum melting and vacuum annealing of metal materials. These pumps can effectively remove impurities and gases from metals, enhancing the quality and performance of metal materials. For example, during vacuum melting, metals can achieve higher purity and better performance.
- Pharmaceutical Industry: They play a role in links such as freeze-drying of pharmaceuticals, vacuum distillation, and vacuum packaging. In the freeze-drying process of pharmaceuticals, for instance, the vacuum pump can maintain a high degree of vacuum in the freeze-drying chamber, allowing ice crystals in the materials to sublimate directly into water vapor, which is then pumped out. This realizes the freeze-drying of materials and ensures the quality and stability of pharmaceuticals.
- Chemical Industry: They can be applied in processes such as vacuum drying, vacuum distillation, and vacuum filtration in chemical production. They help improve production efficiency and product quality. In vacuum drying, for example, they can accelerate the evaporation of volatile substances like moisture in materials, shortening the drying time.
- Vacuum Coating: In the deposition process of various thin films, a vacuum environment is needed to ensure the quality and adhesion of the films. The E2M rotary vane pumps can provide the required vacuum degree, making the coating process more stable and improving the uniformity and density of the coatings.
- Refrigeration and Air-Conditioning Systems: They are used in operations such as evacuation, drying, and backfilling of the systems. They can remove air and moisture from the systems, ensuring the purity of refrigerants and the normal operation of the systems, thus improving the efficiency and reliability of refrigeration and air-conditioning systems.
- Lamp Manufacturing: In the production process of lamps, such as the evacuation and packaging of bulbs, vacuum pumps are needed to extract gas from the bulbs and create a vacuum environment, which helps extend the service life of bulbs and improve their luminous efficiency.
- Scientific Research Experiments: In various scientific research laboratories in fields like physics, chemistry, and materials science, high or low vacuum environments are required for experiments. The E2M rotary vane pumps can serve as supporting equipment for experimental devices, providing stable vacuum conditions for experiments and facilitating the smooth progress of scientific research work.
