Information

Overview

E1M18 - 110/200-240V 1Ph 50Hz or 115-120/200-230V 1Ph 60Hz (IEC60320 power connector C19 - factory set to 230V - Ultragrade Performance 19)

#A34317984

The E1M18 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.
