Pumps in a spinning plant
Polymer pumps – for the most demanding
requirements
Process stability and product quality are heavily influenced by
the polymer in the manufacture of man-made fibers. As the
leading manufacturer of man-made fiber systems, Oerlikon
Barmag knows how the design of the individual systems
components influences the quality of the polymer and hence
the spinning process.
Booster pumps build up the pressure which is required by
the system – with a high degree of flexibility and reliability.
Booster pumps in polymerization or polycondensation
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.
Spinning pumps – innovative and reliable
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:
- optimal melt flow due to rheologically advantageous melt
channels
- highly polished melt channel 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.
Spin-finish pumps – high-precision and maintenance-friendly
with extreme durability
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 PROFIN series is designed for use with all commercially
available types of spin-finish, from high, down to low oil
concentrations. In addition, the production program includes
pumps specifically tailored to handle corrosive spin-finish
liquids. Identical connection dimensions of the PROFIN spinfinish
pumps permit exchange with those of the previous
series.
PROFIN spin-finish pumps convince by
- Long service life
- Operator–friendliness
- Operating stability
- Quality management
