Edwards E1M18 Vacuum Pump Ultimate Vacuum< 3x10-2mbar Inlet Connection NW25 Displacement 25.0 m3h-1 / 14.7 ft3min-1 Features High ultimate vacuum and rapid pumping speed ensure efficient operation across a wide range of laboratory and industrial applications Quiet operation provides a comfortable working environment, reducing noise in sensitive areas Features a pressurized oil system that lubricates pump shaft bearings and rotor sealing faces for reliable performance Maintenance is simplified with an oil sight-glass for easy monitoring of oil levels and conditions at a glance Facilitates easy oil changes with an oil drain plug that allows either gravity or pressure oil drainage for convenience Compact, freestanding design allows flexible use without the need for additional support structures Ideal for use with analytical instruments, leak detectors, helium research, and for backing turbomolecular pumps, showcasing its versatility Edwards E1M18 Vacuum Pump The EM range of oil sealed rotary pumps – renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour – have become the industry standard for laboratory and light industrial applications. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single phase or three phase (four pole) air cooled motor. Each EM pump is supplied with 1 liter of Ultragrade 19 oil, O ring and centering ring, two Allen keys and spares seal for oil drain and filter plugs. For PFPE prepared FX pumps Fomblin® to be ordered separately. This is a single stage oil sealed rotary vane pump which has a pressurised oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior after the pump stops. The pumping chambers are air-tight, so this arrangement also prevents suckback unless the gas ballast valve is open. You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has an oil drain-plug to allow either gravity oil drain or pressure oil drain. If you require a different voltage or model, please inquire with our customer service team.
