MINExpo 2012 Water Session

Accurate water-balance planning over the life of the mine, and reduction of overall water consumption, are critical to a mine’s success.

Extending Pump Life by Changing the Environment of Mechanical Seal Operation

API Plan 23 is one of the seal piping flush plans detailed in the API 682 standards. The plan effectively changes the environment in which the seal operates.

Extending Seal Life

Plan 23 offers improved vapor pressure margin in the seal chamber to extend seal reliability. The reduced working temperature of the seal from Plan 23 operation prevents coking on the atmospheric side of many mechanical seals

Improving Bearing Housing Protection for Small Steam Turbines

Lube oil application flaws and contamination are two of the major causes of bearing failures in small steam turbines.

Contribution to Energy Efficiency

Sealing devices account for only a small fraction of the energy consumed by pumps; the scope for energy conservation at first appears limited. However, the paper details areas where significant energy conservation has been achieved by elegant sealing practices.

LabTecta Life Expectancy

This article examines the statistical life expectancy of the LabTecta bearing protector, supplied by AESSEAL over a seven year period.

Applying low emission API compliant sealing technology to mature pump machinery

High cost of replacing pumps and dependability of existing machines has restricted the wholesale replacement of these assets. Consequently, there are large populations of pumps and seals operating today whose designs date back to the 1960's.

Contradicting requirements in API 682 dual seal design configurations

Mechanical seal designers face opposing challenges when developing dual seals. The requirement to provide optimised seal face cooling conflicts with the need to provide a seal that is tolerant of pressure reversal and abrasive or congealing fluids

API Air Test Analysis: Further Information

This post gives more detailed information on the current specified test, and the steps we took in our practical demonstration of what this test will allow to pass.

Contain 'Normal' leakage from primary seals

Dry containment seals have gained popularity over the last few decades and provided reliable service. The refinery sector has used this sealing technology to limit fugitive emissions.

Advances in dry gas seal technology for compressors

Centrifugal process gas compressors, and also certain rotary compressors, require sealing elements between the pressurized gas-containing volume and the bearing assemblies that support the compressor rotor.

The API 682 Standard 4th Edition

Our guide to the 4th Edition of the API 682 Standard, What's changed and how it relates to shaft sealing systems

Secondary Dry Containment Seals

Containment seals have been widely adopted, however it is our concern that it is very difficult to monitor the integrity of the secondary containment sealing element.

Containment Seal Test Procedure

To test the integrity of mechanical seals fitted with a secondary containment seal.
