Used EDWARDS EXT 501E #9039583 for sale

EDWARDS EXT 501E is an advanced, robust, and reliable rotary vane pump designed for frequent oil-free operation. EXT 501E is engineered to suit the most demanding laboratory and process applications, due to its low starting flow down to 0.01 mbar, high ultimate vacuum down to 0.15 mbar, and excellent ultimate pressure capability up to 5,000 mbar. EDWARDS EXT 501E features a special oil and gas-tight lubrication system, ensuring extended pump life and minimal maintenance. EXT 501E utilizes a stack of engineered, thin, stainless steel vanes for optimal sealing, meaning the pump is able to reach impressive vacuum levels. The rotor blades are mounted inside a precision engineered cubic chamber to ensure a smooth, leak-free operation. The rotors are driven by an external AC motor with variable frequency drive, offering smooth rotor motion and operational control features. An optional soft-start feature prevents shocks during start up. EDWARDS EXT 501E pump body and drive-shaft are constructed with heavy-duty stainless steel to withstand continuous operation. EXT 501E incorporates a high performance silicon carbide dry-pocket seal, ensuring a long-lasting seal without the need of lubricant. The patented seal system consists of two machined silicon carbide contact faces, mounted vertically beneath the rotor. Its rectangular design offers open drainage channels for reduced risk of accumulation and contamination of the evacuated gas. EDWARDS EXT 501E is designed for a wide-range of laboratory and process applications, including distillation, freeze drying, rotary evaporation, and sublimation processes. EXT 501E's robust construction, reliable performance, low vibration, and low noise levels make it a superior choice for a variety of industrial processes. With its ability to handle even corrosive vapors, EDWARDS EXT 501E is the ideal pump for harsh operating environments. EXT 501E is compliant with European CE regulations and vibration standards making it a safe and reliable choice in today's laboratory and process applications.
