Almost no pumping process does not use "dosing" in some way. Dosing technology is used for the production of chemicals and products as well as for their economic and ecologically beneficial application in manufacturing industries. A significant number of users of dosing technology are waterworks and sewage treatment plants, as well as public swimming pools water conditioning. The spreading of dosing technology to increase the quality and economic efficiency of processes requires more information and training on “dosing technology“to achieve optimum results.

A recent Pump audit conducted by Grundfos found multiple opportunties for savings - eliminating $4500 annual maintenance, 97% power consumption, as well as reducing the noise levels that were troubling residents. This case study provided by Grundfos covers the problem, the audit findings, and the solution that was implemented.
In chemical manufacturing facilities, there a wide range of pump types and pump applications.
John Crane recently helped Pumps & Systems editorial staff satisfy reader requests for articles on pump fundamentals. This article was written by John Morton, chairman of the European Sealing Association, and product marketing manager at John Crane. Since Power Generation has no tolerance for down time, your sealing choices can make a significant difference in keeping power reliable.
John states, "At the heart of any power station’s pre-boiler system is the boiler feed pump. Most of these pumps are between-bearings, multistage centrifugal designs with mechanical seals installed at each end of the pump." In this article, John covers:
- What is a boiler feedwater pump?
- Why are these pumps important?
- What sealing methods do plants typically use to keep boiler feedwater pumps running?
- What are the common issues with these methods?
- Are there other options?
What situations make the change to a newer sealing technology worth the cost?

When to use a Centrifugal pump or a Positive Displacement pump (“PD Pump”) is not always a clear choice. To make a good choice between these pump types, it is important to understand that these two types of pumps behave very differently.
