Used EDWARDS EXT 250H #9213617 for sale

EDWARDS EXT 250H is a twin head rotary vane pump designed for operation within the pressure range of 0-100 mbar to 0-100 mTorr. It features two pumping heads that are capable of being run independently of each other, allowing for a more versatile approach to applications where two different levels of vacuum are required. EXT 250H is constructed from high quality components and materials, making it well suited for a variety of pumping processes in industrial and commercial settings. The design of EDWARDS EXT 250H pump head incorporates a rotor and vanes that are optimally engineered to ensure high performance in demanding applications. The rotary vanes are machined from an abrasion resistant material that allows accurate and precise vacuum levels to be achieved quickly and efficiently. The eddy current protection equipment incorporated within the pump head helps protect it from overloads and thermal fluctuations. The housing of EXT 250H is designed to reduce the emission of noise and vibration, allowing it to operate near other systems or personnel without causing disruptions. The air intake of the unit is incorporated with a fluid dynamic designed inlet port which ensures a continuous supply of air to the vacuum system, further reducing noise while maintaining a consistent level of performance. Additionally, the pump's oil circulation unit ensures efficient heat transfer, while the built in cooling fan and oil level control machine help to prevent overheating and provide lubrication of the vanes. EDWARDS EXT 250H also comes with a variety of controls and automatic safeguards to ensure safe, efficient operation. These include a start/stop function, a zero-speed interrupt switch which automatically shuts off the pump once the desired vacuum level is reached, and a vacuum pressure control unit for setting the desired pressure range. This unit also features an alarm tool which sounds when an overpressure is detected, allowing for rapid intervention in the event of a malfunction or unexpected pressure rises. Overall, EXT 250H is an exceptionally robust and reliable pump asset designed for a wide range of industrial and commercial applications. Providing excellent performance and powerful features, it is the perfect choice for sustained, high performance vacuum processes.
