Contact for Pricing

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.

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. For PFPE prepared FX pumps Fomblin® to be ordered separately.
