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.

The Welch DOUSEAL two-stage pumps are designed to be most efficient when operated at or near their ultimate blankoff pressure. The pump is designed to remove air from a vacuum system at atmospheric pressure to a deep vacuum. When the pump is operated at elevated pressures up to about 10 Torr for long periods of time, the pump will run hotter. At elevated ambient temperatures under these conditions, the thermal protection switch on single phase motors may cute out. Use of an exhaust filter with coalescing element is required.

This pump has been fully refurbished and fully tested. It is ready for a wide range of applications.
