The performance of deep-well jet pumps can be optimized to specific pumping conditions through the use of control valves to create the right amount of back pressure, and this article – part two of our jet pump series – will explain their function and how to adjust them.

“What is a jet pump, and how does it differ from a centrifugal pump? A jet pump actually is two pumps in one – a centrifugal pump and a jet assembly, commonly called an injector.”

Looking at the physics of how centrifugal pumps lift water.

A look at the impeller and the diffuser (sometimes called the volute) to see how they affect a pump’s performance.

"This month’s article takes us back to the basics. In this and the articles to follow, we will be talking about pumped water systems."

This month, we will explore the various types of solar-powered pumps available on the market, and some sizing considerations.

"This month, solar energy is in the spotlight as a viable alternative for running a pump."

Windmills have been used for pumping water for hundreds of years, and they remain a viable alternative to electrically driven pumps in remote areas.

"... if these tests fail to identify the problem, or if the pump is not performing up to par, you will have to pull the pump, test and inspect it to make a final determination as to what the problem is, and whether or not the pump can be repaired."

During the last several years, our industry has seen a lot of hype about constant-pressure systems.
