The MS120 Single Stage Rotary Vane Pumps are single-stage, rotary vane pumps oil sealed, driven by an electric motor controlled by an inverter. These high vacuum pumps are suitable for pumping air and small quantity of water vapour only. Pumping of other types of gas or vapours must be declared in advance to Agilent Technologies that will give the conformity to the specific use.
The flanged electric motor is coupled by means of an elastic coupling. The cooling is ensured by a powerful centrifugal fan.
At the pump inlet there is a mesh filter in order to protect it from solid parts having diameter larger than 4.7 mm. Furthermore, an integrated non-return valve prevents the oil coming back and the return of air in the chamber to be pumped down during the stop phase.
In the tank there is a system of oil smokes separation from the discharged air (maximum residual 2PPM/weight corresponding to 2.4 mg/m3).
The separated oil is recovered automatically by the pump. The gas ballast valves prevent condensation inside the pump when pumping down small quantity of vapour.
