Weighing the pros and cons of diaphragm and peristaltic metering pumps
Equipment reliability is a must in small towns like Dunn Center, N.D., where Goulds Pumps turbines and Aquavar controllers are in demand.
Proper selection, installation and maintenance are the key elements in maximizing pump life
My goal is to help you better understand the misunderstood “chemical feed pump.”
A basic understanding will improve your strained relationship
Using Metering Pumps and Degassing Valves
in Industrial Water Treatment Systems
The Diablo Canyon Power Plant at Avila Beach in California utilizes seawater for both cooling water and makeup water for steam generation. Ionics, Inc., Watertown, Mass., designed and built and now operates a complete water treatment system serving the high-purity water needs of this power plant. Over the past eight years, the seawater treatment section has demonstrated excellent long-term performance as a result of strong design, consistent maintenance and qualified operators.
Since the introduction of the metering pump, chemical feed for disinfection has been a primary application. As we move into the 21st Century, it again is time to review how we introduce chemicals such as sodium hypochlorite into our water systems. While the goal remains the same, changes in pump technology have been created to provide more accurate and consistent results. This article will discuss current metering pump technologies, proper pump sizing, installation and future enhancements.
Motor-driven, solenoid and peristaltic metering pumps provide proper control for specific applications and multiple needs.
