  • Vacuum Pumping System Comprising A Vacuum Pump And Its Motor
    Publication number: 20200408212
    Abstract: A vacuum pumping system includes a vacuum pump and a motor for driving the vacuum pump. A motor stator and a motor rotor are received in a pumping chamber of the vacuum pump. Thanks to such arrangement, the vacuum pumping can be made as a single, sealed unit and the need for dynamic seals can be avoided. Moreover, the vacuum pumping system can be more compact and lighter than prior vacuum pumping systems. A pump rotor of the vacuum pump may be at least partially made as a hollow body, and the motor may be received inside the pump rotor.

  • Oil rotary vacuum pump and manufacturing method thereof
    Patent number: 8118576
    Abstract: An oil rotary vacuum pump of mechanical type is filled with a requested amount of oil at the end of the manufacturing process, then it is stored and then shipped to the user, letting the user avoid an operation of introducing the proper amount of oil into the pump. The oil leakage is prevented by securing the suction and/or exhaust ports of the pump, which are sealed by means of a removable sealing member, for instance by means of a membrane.

  • Oil rotary vacuum pump and manufacturing method thereof
    Patent number: 7588426
    Abstract: An oil rotary vacuum pump of mechanical type (100) is filled with a requested amount of oil at the end of the manufacturing process, then it is stored and then shipped to the user, letting the user to avoid an operation of introducing the proper amount of oil into the pump. The oil leakage is prevented by securing the suction and/or exhaust ports (3, 17) of the pump, which are sealed by means of a removable sealing member, for instance by means of a membrane (21, 23).
