The Ilmvac compact rotary vane pump PK 6 D is an oil sealed connecting two-stage vacuum pump, constructed for the special applications of chemical laboratories. The rotary vane pump has an high level of water vapour tolerance, an integrated suction socket valve, which anticipates the back soaring of oil in the recipient after the switch off of the pump. The handling of the pump is very easy because of the very compact construction. The pressure- and suction sockets in DIN-norm makes it possible to connect a lot of components. The control of the oil stand takes place about the integrated oil showing glass. The vacuum pump has a pumping speed of 6 m³/h and reaches a total ultimate pressure of 2 x 10-3 mbar. The water vapour tolerance is 40 mbar, the suction socket is designed in DN 16.
