Combination pump systems are particularly suitable for evacuation jobs in chemical applications with high condensate loads. For the fine vacuum range in special applications, e.g.: • for aggressive gases and vapors • for evacuation of solvent recovery vapor • for pumping of vapors which are soluable in oil The Chemvac Combination Pump Systems are used for producing fine vacuum. They are corrosion optimized combinations of a two stage rotary vane pump with a chemically resistant diaphragm pump. The rotary vane pump is connected on the intake side to a recipient and evacuates it. With a delay the integrated diaphragm pump evacuates the inside of the oil housing. This vacuum prevents the gases from the working valve of the rotary vane pump from condensing and conveys them through a separator system into the exhaust air. Advantages: • High end vacuum • Long periods between oil changes reduce running coasts and down time • Low corrosive loading of the components • Simple pressure condensation after the chemical resistant diaphragm pump • Cessation of a suction-side cooling trap in most cases • Excellent durability with aggressive applications Scope of delivery: Chemvac Combination Pump System with switch, mains cable and plug, KF small flange connections, clampng and centering rings, oil filling.
