Vacuum Pump

  • Dry-type Screw Vacuum Pump

    Dry-type Screw Vacuum Pump

    Compact structure and small footprint.

    Since there is no oil lubrication in the vacuum chamber, the dust does not remain in the pump chamber, but is discharged from the exhaust port with the gas. It also solves the problems of oil emulsification and frequent replacement of working fluid, frequent maintenance and maintenance, and saves the cost of use.

    A gas that can remove a large amount of water vapor and a small amount of dust. After adding the accessories, it is also possible to remove gases such as flammable, explosive and radiation.

    There are no internal valves in the pump chamber, which eliminates the possibility of malfunction due to internal valves, so it is highly resistant to dust and tar.

    No waste water, waste oil emissions, no pollution to the environment.

    The pump chamber and the surface of the screw can be nickel-plated and coated with Hastelloy coating to remove a large amount of water vapor and various corrosive media.

    The ultimate vacuum is high, which can replace most of the Roots water ring and the Roots reciprocating vacuum unit.

  • Water Ring Vacuum Pump

    Water Ring Vacuum Pump

    The water ring vacuum pump is suitable for pumping out gas and water vapor, and the suction pressure can reach 33 mbar absolute pressure (97% vacuum). When using transformer oil as working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7 mbar absolute pressure (99.3% vacuum), in some cases can be used instead of reciprocating pump, when the liquid ring vacuum pump is in the ultimate vacuum (working fluid When working under long-term saturation steam pressure, the cavitation protection tube should be connected to protect the pump. The water ring vacuum pump is mainly used to remove explosive gas and work in various flammable and explosive environments. Its performance parameters are the same as those of 2BV2 and 2BV5 series.

    Vacuum Pump Manufacturers

    The specially designed gas ballast valve is prepared to prevent the pump oil from mixing and prolonging the use time of the pump oil. When the gas ballast valve is opened, the high ultimate vacuum is maintained.

    It adopts international similar product design, small size, light weight, low noise and convenient starting.

    It is equipped with an oil pump structure device, which is forced to automatically feed oil and can work under the atmosphere.

    Anti-return oil, no oil leakage, no pollution to the environment.

  • Scilent Oillesss Vacuum Pump

    Scilent Oillesss Vacuum Pump

    The Scilent Oillesss Vacuum Pump is a new generation of vacuum pumps and is the main equipment for obtaining rough vacuum. Complete isolation of the crankcase and cylinder is achieved thanks to the fully sealed unit; and the piston ring uses self-lubricating material for advanced oil-free lubrication. Because there is no sewage discharge, the Scilent Oillesss Vacuum Pump is especially suitable for vacuum distillation, vacuum evaporation, vacuum drying, vacuum concentration, vacuum impregnation and other processes in the chemical, pharmaceutical and food industries.

  • Minitype Roots Vacuum Pump

    Minitype Roots Vacuum Pump

    The Minitype Roots vacuum pump, a new generation of new products based on the original, uses a pair of 8-shaped rotors to make a constant speed reverse rotation in the pump chamber to generate suction and exhaust. Each rotor is supported by two bearings. The relative positions of the two rotors are always kept constant by a pair of synchronous gears. There is a gap between the rotor and the rotor, the rotor and the pump body, and the rotor and the side cover. No friction, no lubrication required.

  • Hanbell Dry-type Screw Vacuum Pump

    Hanbell Dry-type Screw Vacuum Pump

    The dry screw vacuum pump is a pumping device that uses a pair of intermeshing screws to make a synchronous high-speed reverse rotation in the pump casing, and the two screws are corrected by fine dynamic balance and supported by bearings. Installed in the pump casing, there is a certain gap between the screw and the screw. Therefore, when the pump is working, there is no friction between each other, the operation is stable, the noise is low, and the working chamber does not need lubricating oil. Therefore, the dry screw pump can be removed. A large number of water vapor and dust gas occasions. It is a new generation of oil-sealed vacuum pumps.
