Scroll Vacuum Pumps

The dry compressing SCROLLVAC SC-D pumps operate on the principle of a scroll compressor. Two or more Archimedes spirals engaging each other. The vacuum is generated by reducing the volume of the pockets and compressing gases from the outside towards the inside thereby pumping the gases. SCROLLVAC pumps operate absolutely oil-free with a high effective pumping speed in the whole range of operation. SCROLLVAC...

Three Stages Diaphragm Vacuum Pumps

The DIVAC 1.4 HV3C is a threee-stage diaphragm pump capable of resisting chemicals and offering an improved pumping performance. Its speed is infinitely variable from 700 to 1600 rpm so that he pumping speed of the pump can be easily adapted to differing requirements. The built-in textured diaphragm is made of EPDM and has been coated with PTFE. The valves are made of KALREZ thereby ensuring...
