    DIFFUSION PUMP OPTIONS

     

    ISOLATION/VENT VALVE

    The Isolation/Vent Valve allows the diffusion pump and manifold to remain under vacuum and still be able to vent air into the mechanical vacuum pump when the system is turned off. Venting air into the mechanical pump when it is turned off prevents mechanical pump oil from backing out of the mechanical pump and into the diffusion pump.


    SPECIFICATIONS:

    STANDARD FLOW (Pictured)
    Isolation Valve 0-12 mm
    Vent Valve 0-4 mm
    Exhaust Connection - #18 connector *

    HIGH FLOW (Not pictured)
    Isolation Valve 0-20 mm
    Vent Valve 0-4 mm
    Exhaust Connection - #25 connector **

    * Precision Threaded Glass Compression O-ring fitting accepts 15 mm to 18 mm O.D. rigid tubing.

    ** Precision Threaded Glass Compression O-ring fitting accepts 22 mm to 25 mm O.D. rigid tubing.

    MANIFOLD ADAPTOR

    The Manifold Adaptor, which is also constructed of Pyrex glass, provides the connection between the diffusion pump intake and main stopcock on the manifold. The adaptor is an optically dense baffle to prevent stray vapor molecules from entering the main stopcock. This configuration also aids in installation by allowing more adjustability of the pump body position.


    SPECIFICATIONS:

    STANDARD FLOW (Pictured)
    Manifold end 17 mm O.D.
    Diffusion Pump end 25 mm O.D.

    HIGH FLOW (Not pictured)
    Manifold end 25 mm O.D.
    Diffusion Pump end 25 mm O.D.

    NOTE: A MANIFOLD ADAPTOR IS INCLUDED WITH THE PURCHASE OF A DIFFUSION PUMP. ADAPTORS TO RETROFIT A DIFFUSION PUMP TO ANY MANIFOLD SYSTEM MAY BE PURCHASED SEPARATELY.

    COOLING FAN

    The continuous duty Cooling Fan provides maximum cooling for the air-cooled diffusion pump. This increases pump efficiency and allows the pump to operate at a higher boiler temperature, thereby increasing vaporization and velocity. The cooling fan easily mounts to the support rod and includes chrome plated metal grill, power cord and mounting hardware.

    SPECIFICATIONS:

    For use on both Standard Flow & High Flow models.
    Size 4-5/8 sq.
    Power - 115/120 VAC*
    Air flow Min. 50 CFM
    Noise level - < 60 dB

    *Power cord must be hard wired to power source.
