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. |

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.
