Case study
Efficient submersible pumps for pulp mill water intake
SCA Packaging Munksund, a pulp mill located on the northern coast of Sweden, needed to replace its water intake station, which was built as early as 1928. A new pumping station was built in 2009. Four submersible pumps with high flow and low head were required to lift river water up to disc filters, thereafter being distributed by four AHLSTAR end suctions pumps.
The challenge
When selecting the supplier, an important condition set by SCA Packaging was understanding the customer requirements:
- Knowledge of the demands of the pulp and paper industry, including local Swedish branch standards SSG
- Thorough know-how in pumping station design and operation
- Reliable management of seasonal variations in water quality and flow
- Energy-efficient pumps
The solution
- Supply of four reliable submersible mixed flow column pumps type ABS AFLX, including raiser pipe
- All hydraulic parts and raiser pipe in stainless steel, due to seasonal variations in water quality – pH and humus
- Support for control strategy with variable frequency drives and for how to switch operation between pumps
- Professional assistance in pump sump design
- Trouble-free start-up with Sulzer installation supervision
Leif Risberg - SCA Packaging
With Sulzer we could be sure to have a reliable supplier who knows the pulp and paper industry and delivers efficient submersible pumps.
Customer benefit
As a well-known supplier in the pulp and paper industry, Sulzer understands and is able to fulfill local requirements and standards. The installed pumps were supplied with an option for future upgrades. Today there is a service agreement in place for regular condition monitoring of the pumps, performed by experienced Sulzer service staff. The Sulzer pumps have been operating smoothly and efficiently ever since the start-up.
