KEY FACTS OF CLIENTS:
• Pneumofore in Rivoli (TO), Italy, provides solutions for
industrial vacuum and compressed air applications around
the world.
• With a 65% share of the Indian market, Hindustan National
Glass Industries (HNGI) is the largest manufacturer of glass
bottles and containers in the country, and is also aiming to
become a global industry leader.

CHALLENGE:
• HNGI decided to utilize vacuum pump technology at the new
production lines in Nashik in Maharashtra and in Naidupeta in
Andhra Pradesh.
• Both contain six production lines with twelve sections, with
each line capable of producing thousands of bottles a minute.
• HNGI wanted the twelve production lines at the Nashik and
Naidupeta plants to have:
• sufficient vacuum levels required for high speed and
precise molding of hollow glass containers
• automatically adjustable production capacities.

SOLUTION:
• Pneumofore decided to install six UV50 VS90 vacuum pumps,
each driven by a 90 kW motor operating at variable speed.
• The VACON NXP AC drives controlling the pump motors
enable the rotational speed to vary between 950 and 1750 rev/
min and the flow rate between 1890 and 3240 m3
/h.
• The VACON NXP AC drives permit optimized power
consumption according to changing needs, depending on the
rate of production, number of personnel working or seasonal
changes.
• Operating at lower revolutions reduces energy consumption.

SOLUTION:
• Reduced wear on the moving mechanical
parts results in less need for maintenance
and extends the life of the vacuum pumps.
• The VACON NXP drives help keep the
pressure constant, which is essential for
consistent quality and strength in the glass
bottles and containers.
• VACON Multimaster, special software to
improve reliability and efficiency, keeps as
many vacuum pumps as possible at their
optimum operating point and enables the
pumps to alternate to balance the working
hours and load.

SOLUTION:
• The VACON NXP drives in the vacuum pump system
communicate with each other and are able to judge how many
pumps are needed at any particular time and the speed the
pumps should operate at, and notice if there is a fault in one of
the motors, pumps or AC drives.
• If the demand exceeds the maximum capacity of the leading
pump and more capacity is needed, auxiliary pumps are
connected as required. The leading pump and the auxiliary
pumps run in parallel, which saves energy and reduces wear
on the pumps.

TESTIMONIAL:
“The vacuum pump systems react within a few seconds to
changes in production. It normally takes much longer for
changes to be activated. The VACON NXP with the VACON
Multimaster software provided the best possible solution to
the needs of this application. In Vacon we found a partner with
whom we can make changes to the software to make it more
efficient in a specific application. This approach would have
been difficult with other AC drive suppliers.”
