Used LEYBOLD HERAEUS E250 #9409319 for sale

LEYBOLD HERAEUS E250 is a rotary vane vacuum pump with a pumping speed up to 250 m3/h. It is a two-stage, direct-drive pump with a mechanically sealed, oil-lubricated and oil-sealed design. Because it is oil sealed, the pump is suitable for use in high-pressure applications, making it a valuable consideration for laboratory and industrial applications. The pump utilizes two rotors rotating inside of a permanently sealed housing and a sealed-for-life, maintenance-free oil chamber. Both the inlet and outlet of the pump are outside and connected to a vacuum system. A wire mesh filter mounted at the inlet of the pump traps solid particles, and a replaceable filter cartridge surrounds the pump housing for protection. E250 is designed to provide high reliability and maximum performance, with a maximum continuous operating pressure of 10-6 torr (1 x 10-6 mbar). The pump features a low startup torque and a low noise level, with a sound power level of 67 dB(A) at nominal pumping speed for a 50 Hz frequency. It is fitted with a motor that operates at a maximum power intake of 160 W and has an integrated moisture filter. LEYBOLD HERAEUS E250 pump can function continuously in vertical and horizontal positions, making it suitable for a wide range of applications. The pump also has a rapid self-priming mechanism and a self-regulating oil supply system. To protect the pump components, the rotor and bearings are equipped with built-in temperature sensors to detect any excessive rise in temperature that could indicate an overload. E250 is an ideal choice for laboratories, process lines, and research applications that require a reliable, high performance vacuum pump. The range of operating temperature is between -15°C to 65°C. The vacuum pump also has a wide range of accessories and replacement parts to keep it in good operational condition. LEYBOLD HERAEUS E250 pump is a durable, economic and energy-efficient solution for a variety of industrial uses.
