This E2M28 pump is fitted with a worldwide single phase motor and is factory set to 115V/60Hz. It can be switched to 230V/50Hz on request (just add notes to your order).

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.

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 via a single‑phase motor.

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.
