Retirement and Impellers by Bill Corey I’ve been asked for some time now, “When are you going to retire?” My standard answer was, “In a few years.” Things don’t always work out the way you might want them to. So after a two-and-a-half week run out west, I came home and was told I was no longer needed. Since, I have found my part-time job taking up a lot of my time now. Ronnie and the fine folks at WWDR asked if I wanted to still write. At first I thought, “I’m really not in the industry anymore, so why?” Then I realized I still have things to offer. A letter I received from a reader helped me to know this. So let’s take a look at what makes the water move through a pump. The industry calls it an impeller. There are three different types. The one most used is called a “closed or enclosed” impeller. What this simply means is you have a front shroud and a back shroud. The shroud is a cover to the vanes. The vane starts at the eye and is usually curved as it moves to the edge. I’ve always called the edge the port. It is the proper name, and is the exit of the impeller. So what happens is, the water is pushed into the eye where the vane tips grab it and moves it to the edge port. As it does this, it increases the velocity or speed of the water. This is what you want to happen. The speed of the water is what causes it to go up in pressure. Pressure is what moves the water through the pipes. Now, you must be careful as too much pressure can cause pipes to burst, and this is not something you want to happen. The im- peller diameter is one of the things which determines the speed, hence the pres- sure. We’ll talk more about how the water gets to the eye another time. The port width is what helps determine the flow of water through the impeller. Wide port more water - smaller port less water. Siz- ing is what helps you to know which pump to use. We’ll take a closer look next month.

Saturday is a full education day, starting with an outside demonstration from Geoprobe Systems ® showing direct push best practices for environmental site investigations. During the day, up to three concurrent tracks will cover well inspection, selecting pump control solutions, drill rig safety and maintenance, and more. Sunday has more classes, followed by the ribbon-cutting celebration and trade show opening at 3:30 p.m. Visit the exhibits to see all the great offerings of products and equipment needed to perform your job from beginning to end. The Worth Family Picnic follows at 6:30 p.m. After breakfast on Monday, the trade show reopens until 2:00 p.m. Oh, about the “county fair”, there will be pony and camel rides for kids and adults, plus a petting zoo!
