Features
  • Quiet operation ensures a more comfortable working environment, ideal for spaces where noise reduction is crucial.
  • Features a compact, freestanding design for flexible use across various settings without requiring additional support.
  • Proven reliable performance in a wide range of laboratory and industrial applications, showcasing its versatility and dependability.
  • Incorporates a gas ballast valve, essential for effectively pumping vapor without condensation inside the vacuum pump.
  • Built-in motor protection systems include cooling by an external fan and thermal overload protection that automatically resets.
  • Maintenance is simplified with an O-ring sealed sight glass for easy monitoring of oil levels and conditions at a glance.
  • Designed for effortless oil changes, featuring an oil drain port at the end of the oil box for convenient oil removal.
  • Facilitates easy oil top-ups through a large filling port and a recessed top, minimizing spills and maintenance time.

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.
