API682 4th Edtion
The API 682 standard was established in 1994 as the first stand-alone standard for mechanical seals used in pumps and has gained wide acceptance in the oil and gas industry. It has been revised three times, and the current version is the fourth edition.
This standard stipulates the requirements and recommendations for the selection and operation of mechanical seals in new as well as retrofitted centrifugal and rotary pumps. Its purpose is to reduce lifecycle costs by improving equipment reliability, and to protect the global environment by reducing leakage and emissions from equipment.
The EagleBurgmann group has built a reputation in the oil and gas industry for its reliability and performance as a major global manufacturer of mechanical seals. Since the API 682 standard was first published in 1994, the EagleBurgmann Group has launched approximately 30 models of API 682products . We have decided to integrate all of the bellow seals, which are about one-third of our new product line-up, into EagleBurgmann Japan models and introduce them as global standard products for the API 682 fourth edition.
This allows integrated manufacturing and global procurement of materials. The benefits include reduced production costs, improved flexibility with regard to design and manufacturing lead times, and economical pricing.
The EagleBurgmann Group continue to work to improve seal technology and manufacturing technology, enhance quality management systems, end reinforce the Group's global production and sales structure.

One of the most common types of mechanical seals, a multi-spring seal incorporates multiple coil springs and O-rings and is ideal for the design of simpler and more compact products. The use of a wide variety of materials in the sliding parts and O-rings ensures that these products can be used for various purposes and under a wide range of operating conditions.
Metal bellows seals
With welded metal bellows and grafoil packing, these mechanical seals ensure reliable operation under harshly demanding conditions, such as high temperatures(up to 400℃), high viscosity and high slurry concentrations.
The optimized shape of EagleBurgmann Japan bellows seals results in superior spring characteristics and excellent follow-up performance. These products embody our technology and expertise developed over many years.
Performance and Reliability of API682 mechanical seals
API682 mechanical seals must be able to provide at least 25,000 hours of operation without replacement.
Seal manufactures are required to prove the reliability of their products through API682 seal qualification testing.
Products undergo dynamic and static testing at specific fluids, temperatures and pressures, as well as cycle testing designed to simulate actual operating conditions.
Only products that meet the test requirements relating to seal surface wear and leakage from seals can be approved as API 682 mechanical seals
