In some cases, diluent fluids may be left unrecovered in the process stream, acting as a tolerable contaminant even though it ultimately reduces the purity, quality and value of the final product. A more efficient system is illustrated in Figure 4. It minimizes the amount of diluents that is introduced into the process fluid. pump system optimization
The ultimate dream of a facility manager at any manufacturing plant is to install a piece of equipment and then—except for instances of planned maintenance or for a performance review—forget about it.
Why don’t my PTFE gaskets seal FRP, plastic and other light load flanges?
As we learned last month, carbon/graphite fiber packings have proven to be effective solutions to many common sealing applications. This time, we have learned that flexible graphite packings appear to have become the packings of choice when sealing fugitive emissions, high heat media, and rotating equipment with limited cooling or flush available.
"How long will I be able to run my equipment before it has to be taken down for servicing?" is a question often asked when a buyer or user decides to purchase a new pump, agitator, or other type of rotating equipment.
The right joint sealant can yield significant cost savings.
Bolted flange gasket technology continually evolves with new designs and materials that provide more reliable and durable seals. Plant operators can choose from a wide variety of gasket products that meet the needs of each application; however, selecting the optimal gasket product is only half the battle.
Today's technology has still not perfected reduced contamination sources from mechanical seals. In sanitary pharmaceutical applications, gas seals and "carbon free" seal technologies are becoming more common. New technologies and sealing methodologies are needed to address additional pharmaceutical concerns.
Proper installation and adjustment can make the difference between the success and failure of a packed pump. By keeping in mind the fine points of a few key principles, the chances of success are greatly increased.
