Q.3 What is the difference
between Jet Booster Pump Oil and Diffusion Pump Oil?
Ans. Vapor Jet Booster pumps are built for
creating vacuum very fast. Although the ultimate vacuum of Vapor Jet Booster
pump is not very high, Vapor jet booster pump oil has a lower boiling
temperature so that it boils quickly and creates vacuum.
Diffusion pump oil on the other hand
has a higher boiling temperature and therefore takes a longer time in vacuum
creation. Depending upon the grade of Diffusion Pump Oil being used, these can
give a higher ultimate vacuum when compared with Vapor Jet oil.
Q.4 Why is a Booster Pump
required in a vacuum system?
Ans. A diffusion pump and a rotary
pump form a complete pumping system capable of producing high vacuum. Booster
pump is added to increase the speed of pumping. This reduces the cycle time.
Q.5 Can I use Rotary Pump Oil
in my Roots Blower pump?
Ans. No, this should never be done. Roots
Blower pump requires oil of higher viscosity (90-100 cst at 40oC)
whereas rotary vacuum pumps require oils of lower viscosity. Also types of
additives added in both oils are different.
Q.6 What are the types of Booster
Pumps?
Ans. Booster pumps are of following 2
types:-
1.Roots Blower Booster
Pump- This creates vacuum by rotation of lobes.
2.Vapor Jet Booster
Pump- This pump achieves vacuum by diffusion action.
Q.7 Why is it that Vapor Jet
Booster pump doesn’t create vacuum above 10-5Torr,whereas Diffusion Pumps reach vacuum levels of up to 10-10
Torr?
Ans. A vapor jet booster pump is designed to
create vacuum fast by way of different jet design and lowered boiling temperature
of oil. These changes result in lowering of vacuum level.

1.Engineers do not know
which oil is equivalent to the oil supplied by their plant manufacturer.
2.Equipment
manufacturers rarely give detailed specifications of vacuum oil to be
used.
3.
Equipment manufacturers keep changing their recommendation from time to
time.
4.
The vacuum oils supplied by equipment manufacturers are prohibitively costly
which is a big drain on the very profitability of operations.
5. Availability of oil recommended by the plant manufacturer may not be
there in the country of user.
User
of equipment therefore is forced to pay through the nose and also keep huge
inventory of vacuum oil.
6.
Sometimes vacuum oil being used goes out of production leaving users in the
lurch, For example production of DC-704 was discontinued and equipment
manufacturers never bothered to inform users of a replacement. Users were left
wondering what to use in place of DC-704.
Users
of Vacuum equipment are most of the time wondering “What if a database existed
which clearly told me which vacuum oil can be substituted by what vacuum oil”.
Even better - if this database gave him transparent, easy to understand reasons
as to why one vacuum oil is alternative to the other vacuum oil. This would
surely save a lot of money and botheration for vacuum equipment users.
Based on my exhaustive and in-depth
study of vacuum oils, I have prepared an extensive list of vacuum oils being
used by the vacuum industry and their equivalents/replacement. The list also details the
important properties of these oils because of which these are substitutes.
SV-G9 can withstand temperatures as low as -25°C to as high as 250° C.
Will not catch fire.
Will not be runny at high temperatures.
Will not form solid deposits on the vacuum system in low temperatures.
Conclusion-
In
today’s competitive scenario it is important that production costs are
optimized. Most of the times we are not at liberty to buy exorbitantly priced
oils from equipment manufacturer; neither can we keep a huge inventory of
vacuum oil just because it is not easily available in the country of operation.
Supervac
therefore came up with manufacture of vacuum oils that are-
Reasonably priced
Excellent substitutes for costly vacuum oils
World class quality manufactured using cutting edge technology
Have very long service life
Delivered immediately
Available world over

Although effort has been made
to indicate equivalents of all well known brands of vacuum oils available internationally
but if you find vacuum oil required by you is not available in the list
mentioned above then please write to us with specifications. We will help you find a substitute.
