Medium-consistency pumps

Highest degree of energy savings and innovative fiber separation system

ANDRITZ medium-consistency pumps from the MC series fulfill highest customer expectations regarding efficiency, life cycle, easy maintenance, economic efficiency, and reliability. Thus, they ensure stable production at all times. The excellent economic efficiency has been proven many times, providing energy savings of up to one third compared to other medium-consistency pumps and lower investment costs due to lighter construction.

ANDRITZ medium-consistency pump, MC series


Conveying medium-consistency wet beet pulp suspensions and all types of vicious media is a complex task. ANDRITZ offers a practically tested pump to transport traditional wet beet pulp from extraction systems to pulp presses using screw- or belt conveyors, bucket elevators or positive displacement pumps. ANDRITZ medium-consistency pumps from the MC series fit perfectly into the application to replace existing old systems, as they offer state-of-the-art pumping of wet beet pulp and thus provide major advantages.

In addition to its simple modular design, the greatest advantage of ANDRITZ medium-consistency pumps are the innovative separation system (SMARTSEP). This system was specially developed by ANDRITZ. Due to this integrated degassing system, the first single-shaft solution tried and tested in practice for pumping medium-consistency pulp can be used for almost all media and operating ranges without requiring any vacuum pump. Coordinated equipment sizes cover both the requirements of smaller plants, as well as the full performance spectrum of larger new plants with capacities of up to 5,000 bdmt/day. Moreover, the ANDRITZ medium-consistency pump from the MC series has a flexible volute set-up with four supporting legs and thus can be installed vertically or horizontally with a flexible degassing line arrangement.

Peak efficiencies of more than 70% and ease of operation make this technology particularly efficient. Thanks to the excellent efficiency of the medium-consistency pump and to the variable-speed drive, the pump stands out from the rest due to its low energy consumption.

ANDRITZ SMARTSEP – Degassing system

The greatest advantage of the ANDRITZ medium-consistency pump is its innovative fiber separation system (SMARTSEP). This system was specially developed by ANDRITZ in order to eliminate a major problem in all medium-consistency pumps - that of fiber loss, particularly in run-up operations and at low consistencies.

Medium-consistency pumps used to mainly operate with a complicated measuring and control system to monitor the degassing line. With ANDRITZ SMARTSEP, an additional separation impeller returns fibers reliably to the pump and guides air out of the pump at the same time. This makes it possible to guarantee that there are no fiber losses, and the control of the degassing valve becomes very easy (pump is running, the valve is open, the pump is not running, the valve is closed).
