Product Description

Basic Information

2H series double stage rotary pistonvacuum pumpis a vacuum pump that can exhaust normal gas and gas containing a small amount condensable vapor (gas ballast device should be used).


Features
1) Pump body and the pump cover, the oil tank and the oil tank cover with a sealing groove, take the O-ring seal, reliable sealing, convenient assembly and disassembly;
2) The Oil Separator made of aluminum alloy; attractive appearance; easy replacement.
3) Pump bearing is offshoring, which separated with the pump chamber,supply oil separately, thus it can avoid impurities or harmful gases get into the bearing, prolong the service life of bearing;
4) Equipped with an oil pump, which forced lubrication, especially suitable for the pump for a long time under high inlet pressure condition.
 
Applications:
It's suitable for vacuum smelting, vacuum drying, vacuum coating, electrician, electron, metallurgy, chemical industry, ceramic, aviation, laboratory and other occasions of vacuum coating, vacuum drying, vacuum degassing, vacuum impregnation, vacuum brazing, vacuum heat treatment, vacuum concentration, vacuum reaction, high altitude simulation experiments on the vacuum operation ,etc.
It can be used individually and also combined together with the fore-pump of other high-vacuum pumps such as Roots pump, oil diffusion pump and molecular pumps, etc. It's necessary to add additional devices please, (such as filter, gas-water separator and 1# vacuum oil) in case that gas contains high volume of oxygen, explosive, erosive to ferrous metals, chemically reactive to vacuum oil and more water or dust.
 
Coating Field 
- Optical Coating: Coating anti-reflection films, reflective films, etc. on optical lenses. The 2H series sliding vane pump can quickly evacuate the coating chamber to the required vacuum degree, ensuring uniform deposition of the coating materials and improving the optical performance and quality of the optical lenses.
- Decorative Coating: Coating metal or alloy films on the surfaces of hardware products, plastic products, etc. The sliding vane pump can maintain a stable vacuum environment, making the coating have strong adhesion and uniform color, enhancing the aesthetic appearance and corrosion resistance of the products.
 
Heat Treatment Field
- Vacuum Quenching: It enables metal materials to be heated and quenched in a vacuum environment, avoiding oxidation and decarburization, and improving the hardness, strength, toughness and other properties of the materials. The 2H series sliding vane pump can quickly evacuate the air to ensure the vacuum degree requirement during the quenching process.
- Vacuum Tempering: It is used to eliminate the internal stress of metal materials after quenching, and stabilize the structure and dimensions. The vacuum environment provided by the sliding vane pump can prevent the surface oxidation of the materials during the tempering process and ensure the tempering quality.
 
Drying Field
- Drug Drying: In the production of pharmaceuticals, vacuum drying is carried out for heat-sensitive drugs. The 2H series sliding vane pump can quickly remove moisture at a low temperature, retain the active ingredients and medicinal effects of the drugs, and improve the stability and shelf life of the pharmaceuticals.
- Food Drying: It is used for the vacuum freeze-drying of foods, such as vegetables, fruits, meats, etc. The sliding vane pump can create a low-pressure environment, enabling the moisture in the foods to sublimate and be removed, retaining the nutritional components, color and taste of the foods to the greatest extent.
 
Electronics Field
- Semiconductor Manufacturing: In the processes of photolithography, etching, coating, etc. during the chip manufacturing process, a high vacuum environment is required. The 2H series sliding vane pump can be used as a backing pump to provide a pre-vacuum for molecular pumps and other pumps, ensuring the semiconductor manufacturing.
