Centrifugal and rotary pumps are used extensively in applications involving hydrocarbons. The American Petroleum Institute has an API Standard 682: Pumps—Shaft Sealing Systems for Centrifugal and Rotary Pumps. It:
…specifies requirements and gives recommendations for sealing systems for centrifugal and rotary pumps used in the petroleum, natural gas, and chemical industries… It is the responsibility of the purchaser or seal vendor to ensure that the selected seal and auxiliaries are suitable for the intended service condition. It is applicable mainly for hazardous, flammable, and/or toxic services where a greater degree of reliability is required for the improvement of equipment availability and the reduction of both emissions to the atmosphere and life-cycle sealing costs.
The fourth edition of API Standard 682 was released in May 2014, and indicates a preference for transmitters instead of switches for measuring auxiliary pump seal flush system pressure, temperature and level.
Interpreting data from transmitters can help in minimizing failures, reducing both pump maintenance costs and process downtime, which results in reduced costs and increased revenues.
We hope you can join the webinar and get your questions answered about ways to increase pump reliability and availability to improve the performance of your operations.
