Pumps in a spinning plant
Booster pumps
Booster pumps build up the pressure required by the system
– with a high degree of flexibility and reliability. Booster
pumps in polymerization or poly-condensation plants, also
known as transfer pumps, receive the necessary supply
pressure from the discharge pump. These are used to provide
the necessary pressure for the downstream consumer
units. These consumer units include spinning pumps, flat
nozzles, perforated plates for granulation, etc. Frequently, the
conditions within the system can also change, for example,
through standstill of the downstream units. These demand
flexibility; depending on the application even negative differential
pressures can occur. Oerlikon Barmag booster pumps
solve these tasks thanks to the universally applicable design
of the bearing lubrication system.
Planetary melt spinning pumps
The spinning pump is one of the key components of a
spinning system. Even when used over many years of
production, all Oerlikon Barmag spinning pumps guarantee
consistent yarn quality, the most important factor in successful
yarn production.
The special advantages of Oerlikon Barmag’s planetary gear
spinning pumps include:
- Optimum melt flow due to rheologically-advantageous
melt channels;
- Melt channels with optimized surfaces, ensuring superior
flow conditions;
- High-precision manufacturing methods, allowing for excellent
running performance and stable melt exchange;
- Specially-designed relief grooves in the melt outlet area of
the gears, for minimized compression forces and operation
with few fluctuations in the flow.
Together, these advantages translate into the uniformity of
the melt streams. Rectangular melt spinning pumps are
available on request.
Planetary spin-finish pumps
The more even the application of the spin-finish liquid to the
yarn, the better the yarn quality. A trailblazing design now
sets considerably higher standards in terms of feeding
accuracy, reliability and durability.
The Oerlikon Barmag spin-finish pump concept is based on
the old proven planetary gear pump principle with a centrally-driven
sun gear and four planetary gears.
The balanced force ratio within the pump and the constructively-influenced
low bearing load guarantee low frictional
wear.
PROFIN
Feed accuracy, operating stability, and service life of the
equipment are the fundamental properties of our spin-finish
pumps. As far as the PROFIN series is concerned, excellent
feeding accuracy, optimum internal flow conditions and the
self-venting effect – which prevents the agglomeration of
air-bubbles – are the preconditions for precise, uniform and
high-quality oil-application.
Mixing and metering in polymer processing
Extremely-high metering accuracy and mixing performance
ensure that your products are top quality. There is a series of
systems available for the various feeding and mixing tasks,
optimally designed to fulfill the requirements of flexible production.
Color and additive injection is primarily used with textile
filaments. Nevertheless, injection systems are available on
request for producers interested in mixing and metering.
