D8B / 91256211 Overview:
Fully refurbished Leybold / Oerlikon D8B Dual Stage Rotary Vane Pump coupled with a KF16 Inlet Flange and KF16 Outlet Flange. This Leybold / Oerlikon Rotary Vane Pump has a peak pumping velocity of 6.9 cfm and a final pressure of 1.5 x 10-3 Torr. It has been thoroughly examined and is ready for broad range of applications within the research and industrial industries. The Leybold / Oerlikon D8B Pump comes with an entire 12-Month Warranty.
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.
