Seal Service Centre

Mechanical Seals are critical to maintaining safe and reliable running of vital process equipment. From complex refining techniques to everyday water handling, Mechanical Seals are considered state-of-the-art equipment, and designed to seal off any type of rotating equipment. Mechanical Seals safely contain product that can be expensive, hazardous or flammable.

Therefore prompt and expert attention to seal repair is vital to pumps smooth operation. The mechanical seal is generally the most vulnerable part of a pump, and if the mechanical seal fails, the pump integrity is compromised and production can come to a standstill. Therefore an experienced and resourceful partner is paramount to mechanical seal care, including repair and expertise in order to optimize and extend performance and seal life.
