    Edwards Small Pumps and Pumping Systems

    To meet the diverse needs of applications ranging from analytical instrumentation, wet chemistry, R & D to light industrial, IVS offers a comprehensive range of different Edwards pumping technologies.

    Easy to Service

    All Edwards pumps are designed for easy routine maintenance. Key components are easily accessible and, with RV and XDS pumps, no special tools are required. Service kits of guaranteed parts are available for routine service by the user. Worldwide support from the Edwards service organization is also available.

    Quality Manufacture

    Edwards pumps are manufactured on state of the art machine tools for high consistency of components. For example, RV rotors are manufactured in a robotic cell to remove errors and inconsistencies from the manufacturing process.


    Edwards high performance pumps are used in many industrial and laboratory applications, including the following:

    • Electron microscopes, mass spectrometry, residual gas analyzers and surface analysis
    • Epoxy degassing, powder materials processing
    • Solvent concentration
    • Sterilization, distillation and centrifuges
    • Gel dryers and glove boxes
    • Atomic emission spectrometers, nuclear physics, fusion technology and space research
    • Vacuum ovens
    • TV tube evacuation
    • Automotive system filling
    • Freeze drying
    • Vacuum metallurgy

    The E2M28 pump is a two-stage, direct drive, sliding vane pump. The pump is oil sealed and designed for reliable, long-term operation in both laboratory and industrial environments. 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.

    Supplied with: Ultragrade 19 oil, NW25 O-ring and centering ring, lifting plate.
