ANDRITZ largest medium-consistency pump
Proven performance at highest efficiency
ANDRITZ sets new benchmarks in medium-consistency pumping technology with an efficiency of 74% (BOP) at 8% consistency. This is the highest efficiency ever achieved in this application range.
ANDRITZ’s largest medium-consistency pumps so far with measured efficiencies of 74% at the workshop in Graz, Austria
Six of these pumps deliver reliable performance at a capacity of 4,400 admt/d. They supply a washer designed for 7% consistency and represent the largest medium-consistency pumps built by ANDRITZ. This pump technology supports consistencies of up to 16% depending on downstream equipment.
Fast manufacturing enabled full-range testing at the ANDRITZ pump test center in Graz. The results confirm outstanding performance well above industry standards where typical efficiencies remain below 70%.
The pump ensures smooth operation with a stable characteristic curve and no discontinuities. During pump testing at 12% consistency the pump achieved a capacity of 2,000 m³/h, which is equivalent to 7,200 admt/d.
Like all ANDRITZ medium-consistency pumps these pumps are equipped with the innovative SMARTSEP system. The system removes air from the pulp suspension and transfers it to the degassing line using a specially designed separation impeller. At the same time fibers carried with the air are safely returned to the pump ensuring zero fiber loss. Degassing valve control is simple and reliable: pump running means valve open and pump stopped means valve closed. Operation is stable regarding degassing and fiber loss.
The world's largest medium-consistency pump
Operational success across leading pulp mills
At one of the world’s largest pulp lines in Fray Bentos Uruguay the ANDRITZ medium-consistency pump achieved energy savings of 7 to 15% compared to a previously installed competitor pump. SMARTSEP simplifies control and ensures stable operation. Degassing is stable with no fiber losses since start-up.
At the Mondi Syktyvkar mill in Russia ANDRITZ medium-consistency pumps were integrated into an existing plant as part of a modernization project. The integration challenges were successfully managed and the pump’s easy handling ensured a smooth start-up.
In the Fibria Jacareí pulp plant in Brazil an existing medium-consistency pump was replaced with an ANDRITZ pump. Despite the higher pumping capacity the existing motor could be retained, resulting in energy cost savings of more than one-third.
