Portable system joins large-diameter spliced seals used in pumps and valves
R
epack-S, a French company that designs and manufactures composite seals, has launched a polyurethane (PU) rubber, on-site injection system that joins large-diameter spliced seals used in pumps and valves. Appropriately referred to as OSIS (on-site injection system), this ultra-portable system
enables a completely homogeneous, highintegrity sealing joint to be formed during equipment maintenance – avoiding the loss in mechanical strength often associated with using other seal-joining techniques, claims the firm. 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. However, current seal-joining techniques suffer from various mechanical and structural shortcomings, such as a poor jointed finish. The OSIS system ensures that a much stronger seal joint is formed says Repack-S. It uses PU compounds, precise injection metering and real-time control of the moulding parameters to achieve a homogeneous joint, and a perfectly continuous seal profile. According to the firm, the patented, onsite system incorporates the world’s smallest injection press (less than 2 kg), with a programmable logic controller, for maximum portability, ensuring that seal joints with the highest possible mechanical integrity are formed.

Christophe Rodriguez,
The OSIS seal joining system from Repack-S enables a completely homogeneous, high-integrity sealing joint to be formed during equipment maintenance. It is used to join large-diameter spliced seals – vital parts of pumps and valves.
