Used EDWARDS STP-XA4503CV #293752810 for sale

EDWARDS STP-XA4503CV is a high-performance turbomolecular pump designed for industrial and scientific applications that require high vacuum levels and efficient pumping of gases. Utilizing advanced technology and precision engineering, this pump delivers reliable performance and long-term stability in demanding vacuum processes. At the heart of STP-XA4503CV is a multi-stage turbomolecular rotor assembly that consists of multiple sets of rotating blades arranged in series. These blades are made of high-quality materials such as stainless steel or titanium alloy to ensure durability and resistance to corrosion in aggressive vacuum environments. The rotor assembly is driven by a high-speed electric motor, typically operating at speeds of several tens of thousands of rotations per minute, enabling rapid gas evacuation and creation of high vacuum levels. The pump features an advanced magnetic bearing system that provides frictionless support for the rotor assembly, minimizing mechanical wear and ensuring smooth operation at high speeds. This design eliminates the need for lubrication, reducing maintenance requirements and extending the operational lifetime of the pump. The magnetic bearings also contribute to low vibration and noise levels, making EDWARDS STP-XA4503CV suitable for use in noise-sensitive environments. To enhance pumping efficiency and achieve high vacuum levels, STP-XA4503CV incorporates a built-in variable pitch stator that allows the user to adjust the blade angles dynamically. This feature enables optimization of the pump performance for different gas compositions and operating conditions, improving pumping speed and ultimate pressure. The pump is also equipped with a built-in molecular drag pump that enhances the pumping capacity for light gases and extends the working range of the pump. EDWARDS STP-XA4503CV is equipped with an integrated controller unit that enables precise control of the pump operation and monitoring of key parameters such as rotational speed, temperature, and vacuum level. The controller unit interfaces with external systems via digital communication protocols, allowing for seamless integration into automated vacuum systems. The pump can be operated in various modes, including constant speed, variable speed, and standby modes, to optimize energy consumption and performance based on the application requirements. In terms of specifications, STP-XA4503CV offers a pumping speed of up to 4500 liters per second for nitrogen gas and can achieve ultimate vacuum levels in the range of 10^-10 to 10^-11 mbar, depending on the system configuration and operating conditions. The pump is designed for continuous operation in a wide range of ambient temperatures and can withstand intermittent exposure to high foreline pressures without performance degradation. Overall, EDWARDS STP-XA4503CV turbomolecular pump sets a high standard for vacuum technology with its advanced design, efficient performance, and robust construction. Whether used in semiconductor manufacturing, research laboratories, or industrial processes, this pump delivers reliable vacuum solutions for demanding applications that require high levels of cleanliness, pumping speed, and vacuum integrity.
