Edwards E2M28 Vacuum Pump

Product Information

The Edwards E2M28 Vacuum Pump is renowned for its high ultimate vacuum, rapid pumping speed, and quiet operation, making it the industry standard for laboratory and light industrial applications. This freestanding pump is designed for reliable, long-term operation and has a drive provided through a flexible coupling with a single-phase or three-phase air-cooled motor. The pump's technology includes a totally enclosed motor cooled by a motor-cooling fan, a thermal overload device, and an oil pressure system that lubricates the pump shaft bearing surfaces and rotor sealing faces. With applications ranging from analytical instruments to gas bottle filling, the pump offers an efficient and reliable solution for various laboratory needs. The technical data highlights the pump's displacement, speed, ultimate vacuum, inlet connection, motor power, weight, noise level, and other important parameters. The pump is used, but functions as intended and is confidently backed by a 30-day warranty for 100% parts and labor.
