Edwards E2M18 and E2M28 Rotary Vane Pumps
Starting at: $7,608.00 Starting at: $7,379.76
Edwards E2M18 and E2M28 Rotary Vane Pumps
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) air cooled motor.
Each EM pump is supplied with 2 x 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.
This is a two stage oil sealed rotary vane pump which has a pressurized oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior after the pump stops. The pumping chambers are air-tight, so this arrangement also prevents suckback unless the gas ballast valve is open.
You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has an oil drain-plug to allow either gravity oil drain or pressure oil drain.
Inquire for lead time.
