Improving Pump Reliability and Availability

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.

Tomorrow, May 12 at 2pm U.S. Eastern time, Emerson is sponsoring a webinar hosted by ChemicalProcessing.com. Emerson’s Gary Hawkins will discuss with Chemical Processing’s Traci Purdum the latest changes in API Standard 682 and how to put these changes to use to improve your plant’s availability through automation.

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.

  1. So, originally you had some level switches, or perhaps nothing, and now you install transmitters instead. How do you handle the new I/O? Well, one easy way to modernize the plant is to deploy a plant-wide WirelessHART network. The seal pot measurements can now be done using WirelessHART transmitters, and you can do all sorts of other condition monitoring on the pump as well: such as vibration, bearing and motor winding temperature etc. The same plant-wide WirelessHART network also serves other assets such as the balance of unmonitored compressors, air cooled heat exchangers, cooling towers, and fans/blowers to improve reliability and maintenance productivity.
