The Agilent HS 602 (formerly Varian HS 602) is a dual-stage, oil-sealed rotary vane vacuum pump designed for efficient and reliable vacuum generation in various laboratory applications.

Key Features:

• Pumping Speed: Provides a pumping speed of approximately 17.6 CFM (500 L/min) at 60 Hz, ensuring effective evacuation of vacuum systems.
• Ultimate Pressure: Achieves an ultimate pressure of 1.5 × 10⁻³ Torr, suitable for applications requiring deep vacuum levels.
• Motor Specifications: Equipped with a single-phase electric motor operating at 100-240V, 50/60Hz, offering flexibility in various electrical environments.
• Lubrication System: Features force-feed lubrication provided by an auxiliary gear pump driven by the rotor, ensuring proper lubrication even near atmospheric pressures.
• Design and Construction: The pump’s functional components are immersed in oil within the casing, facilitating sealing of discharge valves, internal lubrication, heat dissipation, and noise reduction.
• Anti-Suckback Device: Incorporates a special antisuckback mechanism that isolates the vacuum system upon pump shutdown, preventing pressure rise and oil backflow.
