Edwards E2M2 Vacuum Pump, 1.5 CFM Rotary Vane, Dual Stage, Hydrocarbon Oil 115 / 220 VAC

Fully remanufactured Edwards E2M2 Rotary Vane Vacuum Pump, R with NW25 Inlet Flange and NW25 Outlet Flange

Edwards E2M2 Overview:

Fully refurbished Edwards E2M2 Dual Stage Rotary Vane Pump coupled with a NW25 Inlet Flange and NW25 Outlet Flange. This Edwards Rotary Vane Pump has a peak pumping velocity of 1.5 cfm and a final pressure of 1 x 10-3 Torr. It has been thoroughly examined and is ready for broad range of applications within the research and industrial industries. The Edwards E2M2 Pump comes with an entire 12-Month Warranty.

The Edwards E2M2 pumps are oil-sealed and designed for reliable, long-term operation in both laboratory and industrial environments. The pumps are free-standind units. The drive is provided through a flexible coupling by a single-phase or three-phase motor. 

The motors are totally enclosed and are cooled by the motor-cooling fan which directs air along the motor fins. 

The single-phase motors have either an automatic or manual reset thermal overload device. When the motor is too hot, the thermal overload device switches off the pump. If the thermal overload device has an automatic reset, when the pump cools down, the device resets and the pump will restart.

Edwards E2M2 Technology:

A rotary vane pump can be described as a positive-displacement pump that is comprised of vanes mounted to a rotor that rotates inside of an enclosure. In some instances these vanes can be of varying length and tensioned to maintain contact with the walls as the pump rotates.

The simplest rotary vane pump is a circular rotor revolving inside of a larger round enclosure. The centers of these two bands are offset, inducing eccentricity. Vanes are allowed to slide in and out of the rotor and seal on all edges, making vane chambers that do the pumping work. On the intake side of the pump, the vane chambers are increasing in volume. These increasing volume vane chambers are filled with fluid forced in by the inlet pressure. Inlet pressure level is actually the pressure level from the system being pumped, frequently just the atmosphere. On the exhaust side of the pump, the vane chambers are decreasing in volume, forcing fluid out of the pump. The activity of the vane drives out the same volume of fluid with each rotation. Multistage rotary vane vacuum pumps can reach pressures levels as low as 103 mbar (0.1 Pa).Visit the rotary vane pump wiki page for more information.
