Valve packing is a necessity for plants trying to contain product and meet the latest emission requirements. However, finding a sealing product that works and has longevity can be a challenge. Graphite-based packing can be a good choice for stem sealing when elevated temperature requirements are necessary. This is due to graphite’s ability to maintain …

Abrasive slurries in chemical processing impose considerable erosive impact on seals, necessitating careful selection of seal types and materials, to both safeguard process liquid integrity and maximize seal longevity.
Many times, valve problems are not a function of the valve at all, but stem from problems with the piping system design, valve location, poor installation practices or selecting the wrong valve for the application.
Wastewater pumps perform a behind the scenes, yet critical, job that most people do not think about. They are found in lift stations and wastewater treatment plants doing their job day in and day out.
Users should be aware of any solids or particles within the material being transferred. Food ingredients such as salsa, fruit fillings and others have large-sized pieces of food within the liquid. Diaphragm pumps with flapper checks and peristaltic pumps are designed to handle solids upward of 4-plus inches in diameter.
There are many considerations when selecting the right pump for chemical applications. When working with materials such as corrosive or flammable chemicals, extra care should be taken to ensure that the product selected is suitable.
Many construction sites require the excavation of materials, such as soil, rock, sand and clay. These sites can be in the form of trenches, pits, caissons, cofferdams and more. For all of these forms, one important environmental factor to consider when managing a job site is water.
One observation is companies ask for a specific size of pump because they rented one in the past and it worked. But that does not necessarily mean the same pump is what was needed in a different situation.
