E1M18 Rotary Vane Vacuum Pump

Overview

The EM range of oil‑sealed rotary pumps – renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapor – 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 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.

Features and Benefits

  • The pump is designed for reliable, long‑term operation.
  • Thermal overload device prevents overheating (single phase only).
  • The drive is provided through a flexible coupling by a single‑phase or three‑phase (four pole) motor.
  • The motors are totally enclosed and are cooled by the motor cooling fan.
  • Full height O ring sealed oil sight glass for easy checking of oil level and condition.
  • Large sight glass and operating oil range.
  • IE3 energy efficient 3 phase motor used with E2M28.
