Various media flow through the containers, leads, tanks or reactors used in industrial processes and put them under pressure. For smooth processes, it is important to test them after production or during maintenance phases. The hydrostatic pressure test subjects the specimens to tightness and strength tests at pressures of up...
Pumps termed as sealless, seal-free or leak-free (the terms are generally interchangeable) became a realistic option for operators in chemical processing applications more than 30 years ago. The first iteration had one main job: perform better at preventing the leakage of hazardous materials than sealed pumps through a sealless design....
Pumping fuels in pipelines over long distances carries a high risk of electrostatic charge due to frictions in the pipeline. In order to avoid a momentous explosion, a small amount of antistatic additive is added to the fuel to increase its conductivity. In that process, the correct volume flow plays...
When it comes to dynamic sealing, the “best solution” is not always the “right solution.” Economics play heavily into seal selection. A user must weigh the benefits of reduced leakage – improved efficiency, reduced emissions, and/or increased reliability – against the cost to purchase and install the seal. Brush seals,...
AODD Pumps for High-Pressure Applications Almatec® AHD and AHS Series Air-Operated Double-Diaphragm (AODD) Pumps have been specially designed to provide a safe operation in high-pressure applications up to 15 bar (218 psig). A typical application of these pumps is filter press feeding. AHD Series pumps utilize an internal...
The goal of any pumping system is to be as efficient as possible. This allows end users to reduce energy costs, maintenance downtime, and increase productivity. An efficient pumping system is designed to transfer fluid (which can range water to concrete) by means of the most direct and unobstructed path...
