  Edwards E2M28 Two Stage Rotary Vane 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) motor.

  Each EM pump is supplied with 1 litre 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.

  Technology

  The motor is totally enclosed and is cooled by the motor-cooling fan which directs air along the motor fins. The motors are fitted with a thermal overload device. When the motor is too hot, the thermal overload device switches off the pump. The thermal overload device has an automatic reset; when the motor cools down, the device resets and the motor will restart.

  An oil pressure system 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 (suckback) after the pump stops. The pumping chambers are air-tight, so this arrangement prevents oil 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 two oil drain-plugs to allow either gravity oil drain or pressure oil drain.

  Agilent IDP-15

  The new Agilent Varian IDP-15 dry scroll vacuum pump is designed for extremely quiet < 50 dBA and low vibration operation, delivering a peak pumping speed of 9.4 cfm (15.4 m3/h) at 60 Hz, and produces an ultimate pressure of 10 mTorr. These new Agilent IDP-15 dry scroll pumps are hermetically-sealed being appropriate for rare gas and helium 3He recirculation applications. The hermetic design with the vacuum space completely isolated from the motor and bearings provides a clean gas path through the pump, which eliminates any risk of oil or grease contamination. These key design elements of the IDP-15 allow the motor and bearings to run at atmospheric pressure which isolates them from being exposed to any vacuum process gases or water vapor from the application. The Agilent IDP-15 supports a global single-phase motor for operating voltages ranges between 100-120V or 200-230 VAC at 50/60Hz and incorporates a easy accessible simple switch to change between high and low voltage use.
