Used VARIAN V 250 #9231302 for sale

VARIAN V 250 is a high-performance turbomolecular pump designed to create high-vacuum environments with minimal leakage. It provides an ideal solution for research and analytical applications requiring pressure control in a wide range of operating conditions. The pump features a patented parallel-blade design to deliver superior performance and is capable of achieving pressures as low as 0.02 mbar. VARIAN V250 features a motor-driven blower to provide fast response and long-term stability even with heavy loads. The motor is powered by an inbuilt current-regulated power supply that allows the user to select any operating parameters from reliable low current to high voltage operation. V-250 also features a unique patented adjustable ball-bearing-supported throttle valve, which helps maintain a constant pressure in a wide range of operating conditions without vibration or mechanical wear. The adjustable valve further reduces noise while ensuring stability and low operating temperatures. To ensure reliability and safety, VARIAN V-250 includes a built-in over-temperature protection circuit which shuts off the motor if it reaches 250˚C. V250 has been designed and manufactured with a focus on energy efficiency. By using a dynamic radial-flow design, the pump minimizes power consumption, allowing it to operate with a minimum input power of only 120W. This makes V 250 highly efficient even at low levels of vacuum. VARIAN V 250 also includes an advanced sealing system which eliminates leaks and reduces the need for precise mechanical alignment. The design of the pump is both high-inertia and low-inertia, allowing for a smooth start without vibration or rattling, while the integrated drive cable allows the motor to be shipped and relocated with minimal effort. VARIAN V250 offers both superior performance and reliability, making it the perfect solution for high-performance vacuum applications. The pump's robust design and the advanced features mentioned above make it ideal for use in analytical and research vacuum laboratories.
