Specialized products for the mining and mineral processing industries.
ProPack AG supplies seals that are perfectly suited for general applications involving abrasive slurries. From cost-effective, general-purpose packings made of abrasion-resistant synthetic yarns and lubricants for superior chemical resistance and conformability. Built to withstand harsh slurry environments.
- Ideal for abrasive and crystallizing media
- for use with aqueous solutions
- to reduce installation time
- Reduce maintenance costs and optimize plant performance
Preferred packing for sealing abrasive mediums in pumps, mixers, agitators and other rotating equipment; Excellent when used in crystalizing products; Low Coefficient of friction and ultimate heat conductivity; High plant standardization possibilities. Recommended Shaft Surface Hardness HRC35
Excellent Standardisation features; Cross section impregnation avoids the penetration of crystallizing mediums; Wear resistant against abrasive products and with minimal coefficient of friction; Self lubricating fiber with high Carbon content, reduced shaft wear and excellent heat transfer characteristics; Thermally balanced construction, the coefficient of expansion is similar to steel, the packing is volume stabile and does not shrink. Therefore minimal re-adjustment needed after installation; excellent chemical resistance; Recommended shaft surface hardness: HRC 45
In an iron ore mine, iron ore rock and slurry with a pH of 10 had to be sealed in a Warman pump. The speed of the 178mm / 7.00 shaft was 900 rpm. Pressure 6 bar / 85 psi at ambient temperature Sealing was done with a 25mm / 1” standard glass PTFE packing and 4 rings and had a service life of 2 weeks. The reason for failure was uncontrollable leakage. The shaft sleeve was heavily worn by the packing used. The packing was very difficult to remove, and this cost extra assembly time. The P9Blue was used as Upgrade. It retracted quickly and held the required drip rate for 1 week without further adjustments. The service life exceeded 3 times that of the previous installation.
