Pfeiffer Vacuum Standard pumps

The performance data of the standard pumps (A series) are shown in Table 2.12. These performance data also apply to all other series. The maximum differential pressures are a function of the overflow valves. In the ADEx series, these maximum differential pressures are smaller than for the other series in order to satisfy the temperature requirements specified by the ADEx guidelines and are shown in parentheses in the table. The housings for these pumps are manufactured of cast iron and are tested at 1 bar overpressure. The seal to the atmosphere consists of radial shaft seal rings. The standard pumps are characterized by their robust, compact design as well as by their high compression ratios, which result in high pumping speeds for the pump combination, even with small backing pumps, and thus afford short pump-down times. The vertical direction of flow renders this pump largely insensitive to dusts and liquids.
