Cuisery, France - Composite sealing specialist Repack-S has launched a new polyurethane on-site seal-joining system, called Osis, for large- diameter pump and valve seals.
Repack-S said in a news release that the "ultra-portable" Osis system ensures a completely homogeneous, high-integrity sealing joint during equipment maintenance, "avoiding the loss in mechanical strength experienced with other seal-joining techniques."
The French company noted that large-diameter homogeneous seals in pumps and valves are often replaced with split seals during the first scheduled maintenance interval, in order to avoid the time and cost of dismantling equipment. Repack-S claims current seal-joining techniques "suffer from various mechanical and structural shortcomings."
The company says its Osis system includes the world's smallest, PLC-controlled (programmable logic controller) injection press (<2kg) for maximum portability.
