EagleBurgmann Pulp and Paper Solutions
Sealing a 5-ton shaft quickly and safely in the Pulp and Paper industry:
EagleBurgmann can help.
A typical paper mill produces over 400,000 tons of pulp and 80,000 tons of paper per year. Smooth production of elemental chlorine-free bleached (ECF) long fiber sulfate pulp relies to a great extent on the sealing technology used in the individual processes. Seals not only perform the important task of protecting employees, machinery and the building from the chemicals that are recovered there for pulp production, they also reduce maintenance costs in the long term.
SITUATION
The pressure disk filter separates white liquor from lime slurry. Any failure to the sealing solution of the disk filter would guaranteed cause an unplanned shutdown of the complete pulp mill. Therefore reliability was the key criteria for the seal design requested from EagleBurgmann.
OUR SOLUTION
EagleBurgmann specially adapted a seal for use in filter machines of well-known manufacturers for the paper and pulp industry. The robust EagleBurgmann LP-D has various distinctive design features, making this seal unique in its kind: from dynamic O-rings not located directly on the shaft but within the seal, to stationary springs on the product and atmosphere side which counteract leakage by compensating shaft movements to keep the sealing gap consistently closed.
The seal is supplied with pressurized buffer water for optimum supply and to prevent the medium from penetrating the seal.
QUICK ASSEMBLY
Because of the immense impact of a seal failure, the customer placed great value on a reliable seal and a simple assembly and disassembly process. Since the EagleBurgmann seal is a cartridge design, work on the five-ton shaft can be completed relatively quickly.
To ensure convenient and reliable fixing of the seal during transport, assembly and disassembly, the assembly fixtures are made of robust material and are dimensioned accordingly. The shaft sleeve is so stable that it can withstand many assembly and disassembly processes.
SUCCESS STORY
The LP-D mechanical seal from EagleBurgmann has been used satisfactorily in the pulp mill on the drive and non-drive side of the shaft since 2010. The MTBR of three years has exceeded the expectations of operators, and reduced the costs for the seal service to a minimum.
