Chemvac Combination pumps Manufacturers

Chemvac Combination pump converts aggressive vapours into fine vacuum. Some chemical applications generate extremely aggressive vapours. This produces a strong condensate burden when operating a vacuum pump at pressures of 3 x 10-3 mbar. For this, chemvac combination pump is ideal. The combination pump consists of a rotary vane pump, which generates a fine vacuum, and a diaphragm backing pump, which handles the condensable vapours by generating a vacuum in the oil box of the rotary pump. In this way, condensation within the oil stages is prevented. This is essential to ensure the long service intervals and long life of the pump.
