Using the existing packing solution in aggressive contaminated water conditions with abrasive particles of iron dust coming from blast furnace, the customer experienced frequent packing failures (on a weekly basis) due to mechanical damage and chemical attack. This resulted in an unacceptable leakage rate and excessive maintenance and replacement costs.
Centrifugal pumps pumping water contaminated with iron dust from blast furnace.
General service packing manufactured from synthetic yarn.
To overcome the harsh environment, Lionpak 2506 was supplied. A high performance packing made of ePTFE / graphite yarn at the face reinforced with carbon fibre at four corners, this solution is a very cost effective packing highly recommended for pumps handling chemical slurries, contaminated water, industrial water, effluent, bauxite slurries, bottom ash slurries and other slurries.
The use of Lionpak 2506 enables the customer to significantly increase packing service life, now reported as up to 3-4 months. As the product can withstand operation in a chemical and abrasive environment significantly longer than general service packing, the customer is able to realise improved efficiencies and reduced maintenance efforts.
