blades with changing pitch that enable excellent pulp 昀氀uidizing,
degassing, and pumping results in the demanding pulp and paper
mill processes.
Pumping systems with Fluider™ technology are mostly used
after washers, thickeners, 昀椀lters, and reaction towers to pump the
stock to the next process stage or to a washer. The MC pumping
systems can also make sure that bleaching liquid or process
chemicals are mixed into the stock ef昀椀ciently. The main advantages
of this technology include high levels of ef昀椀ciency – thus reducing
power consumption – and its ability to maintain an exact turbulence
level, which prevents the over-treatment of the 昀椀ber. Another distinct
feature of the Fluider™ impeller is its ability to work ef昀椀ciently
irrespective of the stock level in the dropleg. The MDL dropleg is a
barrel-like tank at the low-pressure side of the pump that ensures
proper in昀氀ow conditions for the MC pump.
The MCE pump series covers capacity ranges of 10
to 10’000 admt/d and pump heads up to 240 meters. Material
alternatives for these pumps are duplex steels like A-890 grades 3A
and 5A. 654SMO or titanium can be selected as the best corrosionresistant material for the wetted parts of the MC pump.
Problem solving with TMS tower management system
Do you have problems related to storage towers? Is the
retention time of your storage tower insuf昀椀cient? Do you suspect
that your tower is channeling? Do you suffer from occasional
unexplained consistency variations? Do you have problems with air
or bacteria in the pulp? Do you want to run a big storage tower with
a high production rate, and you need small discharge consistency
variations? Do you need a high-consistency storage tower with
low- consistency discharge? Do you have problems related to pulp
quality? Are you running a storage tower with a low pulp level and
want to save energy in pumping?
If your answer is yes to any of the above questions, then
Sulzer’s TMS tower management system could help your process.
Sulzer TMS tower management system
Sulzer’s TMS tower management system controls all
pumping and mixing requirements in tower process applications and
is based on proven and innovative solutions and products.
The TMS tower management system is designed to improve
the performance of any kind of tower, regardless of inlet or storage
consistency, shape, or size. The system can be utilized with straight
towers, such as high-consistency bleaching and storage towers,
reduced bottom medium-consistency storage towers, blow tanks,
low-consistency broke towers, and more.
