Siemens 2BH1600-7AH16 Pump

Siemens 2BH1600-7AH16 is a three‑phase side‑channel vacuum pump in the 2BH family (often cataloged under Nash Elmo Gardner Denver baselines) designed to generate dry vacuum for process control and pneumatic systems. The 50 Hz version delivers 2.2 kW and runs at 2870 rpm, with supply voltages of 200–240 V in Delta or 345–415 V in Wye and currents of 9.7 A (Delta) or 5.6 A (Wye); the 60 Hz version increases to 2.55 kW and 3450 rpm, with 220–275 V Delta or 380–480 V Wye and currents of 11.2 A (Delta) or 6.5 A (Wye). The pump weighs about 27 kg and the sound level is typically around 69 dB(A). It is specified to tolerate a maximum intake pressure of 2 bar absolute and can achieve vacuum levels in the vicinity of 190 mbar at 50 Hz and up to about 210 mbar at 60 Hz, depending on configuration and supply; the model is compatible with accessory control valves such as Fisher Controls valve type 289H‑41 (07‑04) to tailor performance.
