Used ULVAC DA-121D #9386921 for sale

ULVAC DA-121D is a high-performance, oil-sealed, rotary vane pump designed to provide vacuum capabilities up to 1 x 10-2 Torr. With an operating speed of 1400-1700 rpm, it is used in a variety of applications, such as semiconductor processing, metal deposition, thin film coating and etching. DA-121D is constructed out of two steel blocks - the top and bottom sections of the pump. Inside the pump is an eccentric-rotor mechanism that is driven by a motor which is attached to the outside of the pump. This motor is surrounded by two air-filled chambers which are separated by a partition wall. These chambers help to reduce noise and maintain efficient operation of the pump. The rotor has a number of slots in it, allowing for the sealant oil to enter and create a seal between the outside of the rotor and the chamber walls. This oil-seal eliminates air leakage and maintains a high level of pumping efficiency. The sealant oil helps to reduce thermal expansion in the equipment as well as protecting the pump from wear & tear. ULVAC DA-121D pump is designed to handle both continuous and intermittent operation. Its sophisticated operating system is integrated with an incorporated vacuum meter, accurate vacuum control unit and an oil-level control machine. The vacuum meter indicates the vacuum level and displays the differential pressure. As a sophisticated and high-performance vacuum pump, DA-121D offers a number of excellent features, such as a vibration dampening tool, easy maintenance and durability. Its lightweight design makes it ideal for portable applications. ULVAC DA-121D provides extensive installation and operation manuals to make sure the pump is set up correctly and operates smoothly. Furthermore, it is fitted with a safety cut-off switch to prevent accidental over-pressure. DA-121D is a powerful and reliable vacuum pump that provides excellent performance and comes with a range of features designed to ensure a safe and efficient experience. Its installation and operating procedures are simple and reliable, making it an ideal choice for any vacuum application.
