Oil sealed rotary vane vacuum pumps E1M18, E2M18 & E2M28
Description
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.
Specification
• 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.
Applications
• Analytical instruments.
• Leak detectors, helium.
• Research and development.
• Backing turbomolecular pumps.
• Automotive.
• Beam lines and high energy physics.
• Centrifuges, ultra‑high speed.
• Coating.
