Oil Sealed Vacuum Pumps

Oil sealed rotary vane vacuum pumps are being used in all areas of vacuum engineering. They are equally suited for both industrial production and research applications. They may be used to generate a rough and medium vacuum or as backing pumps in pump combinations with Roots vacuum pumps or high vacuum pumps. Rotary vane pumps are built as one- or two-stage pumps. The ultimate pressure range, depending on the model, is between 0.5 mbar and 5•10-5 mbar. The comprehensive pumping speeds range from 1.5 m³/h up to 13,000 m³/h.

TRIVAC

Two Stage Oil Sealed Rotary Vane Pumps

The two stage, oil lubricated TRIVAC B is the logical step ahead within the well-proven TRIVAC concept. Here the performance and the characteristics of the pumps have been adapted without compromise to market requirements. The TRIVAC B pumps with their comprehensive range of accessories have proven themselves time and again as rugged pumps in many and varied applications. The ultimate pressure is about 10^-4 mbar. The pumping speed, depending on the pump size, TRIVAC D 4 B to TRIVAC D 65 B, is in the range from 4 to 65³ /h (2 to 38 cfm).

TRIVAC E
