The pump competence center Bodenheim
GEA develops and produces its complete hygienic pump portfolio in
the pump competence center in Bodenheim: the highly flexible VARIPUMP
line for complex applications as well as the more standardized
SMARTPUMP line.
How GEA Hilge NOVATWIN works:
Conveying and cleaning with one pump
Twin screw pumps have two screws which interlock without contact and
form a closed chamber together with the pump housing. The screws rotate
and thus move the medium along the screw axis from the suction
to the discharge side. Like positive displacement pumps in general, twin
screw pumps stand for the gentle conveyance of lumpy, shear-sensitive
and abrasive media. They offer exceptionally high flexibility for pumping
liquids of different viscosities.
The special feature of the twin screw pump is its dual function,
as they can not only pump the actual, often highly viscous
product, but can also function as a CIP pump, as they can also be
operated at very high speeds. Compared to alternative solutions,
the use of an additional CIP pump can thus be saved.
The self-priming, hygienic GEA Hilge NOVATWIN enables safe
operation with low pulsation and low noise levels at high product
viscosities, temperatures up to 135 °C and differential pressures up
to 25 bar. The system pressure of 30 bar also allows the pump to be
used in high-pressure applications. It enables one pump to handle
both sensitive viscous media at low speed and cleaning media in the
CIP process at up to 3,000 rpm. A constant flow at different pressures
and volumes is another advantage. Due to its self-priming property
(suction height up to 8 meters), other application areas can be served.
For special requirements due to the pumped medium, GEA offers
additional options such as a heatable or hardened pump housing.
The heatable housing as an option allows the pump chamber to be
heated or cooled depending on the temperature requirements of the
pumped medium.
Keyword "hardened pump housing": In case of abrasive media the
screw spindles and additionally the pump housing can be hardened to
increase the lifetime of the pump. Due to the low-pulsation and gentle
pumping, the properties of the pumped media are retained in their
appearance, structure and size. By using different screws with different
pitches, the pump can be optimally adapted to the pumped medium
in terms of solid size and differential pressure. This also enables gentle
pumping such as yoghurt with pieces of fruit or meat salads with solids
with a diameter of up to 44 mm.
Designed according to strict hygiene guidelines
The delivery of hygienically perfect and high-quality liquids requires absolutely
clean pumps. They must be cleaned immediately at the end of a
production and absolutely clean and free of bacteria at the beginning of
a new production phase. "Cleaning" refers to the process in which the
surfaces are completely freed from adhering product, deposits, etc. A
carefully cleaned surface is free of visible, tangible or chemically detectable
residue of contamination. The GEA Hilge NOVATWIN is designed
according to EHEDG guidelines and complies with 3-A requirements.
Advantages of GEA Hilge NOVATWIN at a glance
• Due to the axial, low-pulsation conveying, even sensitive products
with large solids remain intact.
• The use of one instead of two pumps for production and CIP
process saves investment costs and simplifies installation.
• Good suction performance due to tight manufacturing tolerances
and resulting in narrow gaps in the pump.
• Hygienic design ensures fast and safe cleanability, saving time,
resources and increasing production reliability.
• Hardened surfaces also allow problem-free pumping of abrasive media.
• Numerous combinations of screw diameters and pitches allow
optimum adaptation to the desired duty point and application.
