We offers mechanical seals for process pumps with high reliability and excellent value for money. Within the production range are the following types of mechanical seals as defined by API682 Standard:
- by Arrangement - Arrangements 1, 2 and 3 (single, tandem, and double)
- by Type - Types A, B and C (o-ring type with multiple springs, welded metal bellows type with static o-rings, and welded metal bellows type with flexible graphite secondary seals).
We have extensive experience in supplying:
- seals and seal systems for new projects;
- seals for existing pumps and seal systems, to improve MTBR;
- seals and seal systems to retrofit existing pumps, often from single seals to dual seals, to improve industrial and ecological safety.
