The Agilent DS 42 dual-stage rotary vacuum pump is typically used with series 5975 and 5977 gas chromatography / mass spectrometry systems, models 5975A, 5975B-MSD, and 5975C. The pump works with force-feed lubrication, provided by an auxiliary gear-pump driven by the rotor of the vacuum pump itself. This ensures proper lubrication even when pressures are close to atmospheric. The entire pump functional block is immersed in the oil contained in the casing. The oil guarantees perfect sealing of the discharge valves, enters the pump to ensure lubrication and sealing of the parts inside, facilitates heat dissipation and reduces pump noise.


  • Pumping speed: 1.2 cfm
  • Ultimate pressure: 4 x 10-3 mbar
  • Free air desplacement: 45.5 l/min
  • Inlet flange: DN 16

The DS-42 pump is equipped with a special anti-suckback device which automatically isolates the vacuum system when the pump stops. This avoids rises in pressure or oil flow in the vacuum system while air is allowed back into the stator chambers. There is one oil seal on the rotor shaft, preventing oil from seeping out of the pump. This seal acts on a bushing fitted onto the shaft. The vacuum pumps are connected directly to the electric motor through a flexible coupling, so that motion is transmitted even in case of poor alignment.
