Agilent Varian DS102 Dual Stage Rotary Vane Vacuum Pump, Part Number 9499315

The DS 102 is a dual-stage oil-sealed rotary vane pump that delivers a pumping speed of 5.0 m3/hr at 50 Hz,  3.5 CFM at 60 Hz, with a base pressure of < 2 x 10-3 mbar. The DS 102 has a universal-voltage single-phase electric motor with integral power switch.

DS 102 rotary vane pump, 114 L/min, free air displacement at 60 Hz, 1 phase motor (100-120/ 200-230 V) +-10%, 50/60 Hz

  •  Used for light gases, they produce low noise with minimal oil backstreaming, and have a long operating life
  • (PN): 9499315


Forced Oil Circulation

The dedicated oil circulation gear pump ensures efficient and reliable lubrication of the pump from atmospheric pressure throughout the entire vacuum operating range.

Dual Stage Pump

The two stage design allows low 10-3 mbar operation, low operating temperature, minimal back-streaming at low pressure, good pumping efficiency and gas ballast in the high 10-3 mbar region.

Inlet Isolation Valve

An inlet isolation valve is integrated into the pump to close off the inlet port whenever power to the pump is interrupted. This antibackstream valve retains vacuum in the roughing, or foreline, and prevents pump oil from contaminating the vacuum chamber. The DS 102 has a manual gas ballast valve, which when opened, allows the pump to achieve its rated water vapor handling specification.

Built-in Oil Shield

This feature minimizes the oil mist at the pump exhaust. Apart from drastically reducing the oil consumption over long periods of operation, this results in a reduction of air pollution limiting the impact on the environment.

Forced Air Ventilation

The cooling fan between the motor and the pump reduces the pump operating temperature, lowers the oil vapor partial pressure, minimizes oil backstreaming and vacuum system contamination.

Pumping Speed: 3.5 CFM

Base Pressure: < 2 x 10-3 mbar

Inlet Connection: NW25
