Very low RPMs, very old pump actually. So when somebody ever asks the question, "How long does my pump last?" well, I like to show this picture, because this pump was installed somewhere in the neighborhood of about 1958, '59. And they've done very little maintenance to it, other than obviously some bearing work and some seal work. But, you know, in that amount of time, that's pretty exceptional service. And then we go all the way down to the smaller pump that you see in the next picture, that little Aurora Pump. The two tags that you see, the one that's on the pump and the one that's in the picture to the right, those are not the same pumps. But, you know, this is a relatively new pump and an installation. It's a vertical stack pump. It has several little impellers underneath there, and it's in the application of doing a fire, a fire suppression system. It's maintaining this, the jockey pump and the fire prevention system. And later around this we go on to the presentation here. I'm going to point out some things that are very, very important in your facility that if you haven't done it yet with the day and the age that we have with the modern cellphone service and such we all got, we're all carrying around little microcomputers on our hips... I always tell people, "If you get the opportunity, take a picture of that pump tag." Reason why I ask that question is, "Have you got a picture of your pump tag? Do you know what your pump is?" Those kind of scenarios, if you have an opportunity to take a picture of your pump tag when it's in the condition it is you see in the picture there, the third one from the left, this comes in very handy.
Because chances are in your facility, somewhere along the line, you might have the opportunity to send in what I call the painting ninjas. And those are the guys that go in and paint everything, including all the pump tags. So it's always a good idea to take a picture of that someway shape how, but leave it attached to the pump. I've seen in a lot of facilities where particular customers will actually take or move that tag and put it in a file, and then the file cabinet gets moved, and they can't find the pump tag. And then they need support, or they need help, or they need parts, trying to figure out why the pump's not working. And without the pump tag, you're kind of only guessing what's going on with this pump. So this is probably one of the most important pieces of information in your facility that you should kind of keep what I say keep holy. Keep it in a good place so you can find it. The information that's on there will help you get parts, it will help the maintenance people troubleshoot it. It will tell you exactly what it is, what it should be doing, so all those kinds of fun things. Now, as far as pumps that are kind of unique to their application, the one that's on the far right-hand side is actually a fire pump. And everybody says, "Well, why is a fire pump so much different than any other pump that I ever see?" Well, fire pumps are typically there to only run when the fire suppression system is needed.
So usually it's when your building's on fire. And, unfortunately, this is one of those pumps that tends to have a lot of maintenance done on them, because individual insurance companies, local codes in internal building requirements, require this pump to be tested and inspected on an annual basis. And some people will always say to me, they go, "How come my fire pump has to have so much maintenance done on it?" And I guess the answer to that one is it's that you want it to work when the place is on fire. You know, you don't get the luxury of saying, "Oh darn, this pump's not working while my building's burning down." So, keeping that in mind, this is one of those maintenance-intensive things. The other thing you'll notice when you see a fire pump, you could actually have this very same pump doing something else besides fire suppression work. And in that case it's not going to be painted red, it's going to be painted blue, like you see the pump and the pump tag in the picture on the third one from your left.
Fire pumps are typically painted red for a particular reason to denote that they are fire pumps. And the other thing that you should know about a fire pump is you'll never see the word "head" on the pump tag. Typically you'll see the gallons permitted and the pressure that it's rated at. The pump tag that you see there that says, "Aurora Pump," that's actually off of a booster pump package in an Air Force base, and it's rated at 500 gallons permitted at 170 feet of head. So when you ask that question, "What is head?" Head's a dimension. We're going to get into that a little bit later on. But I like to have the pump tag handy, because that tells me where I need to go. So that's one of my most important things that I kind of promote. Keep that pump tag in a safe place. Take a picture of it, put it in file, print a bunch of picture of it, put them in file cabinets someplace in case those pump ninjas get out there and get that pump tag painted.
So in our facility, like I said before, a lot of times we don't pay particular attention to the pump, because pretty much the pump if it was put in the correct application. Other words we had a really good engineer decide what kind of pump we needed for the job that it's doing. So when we're troubleshooting a pump, I always ask the questions. It's basically you'll notice throughout this whole presentation, I call it, "The W’s Troubleshooting." You say, "What is the pump not doing? And what is the pump doing?" When I ask, "What is the pump not doing?" typically the first complaint that comes up, they say, "There's something wrong with the system. It's got to be the pump." Well, when you go to the operator, typically they kind of shrug their shoulders, and they say, "I don't know, it was working great yesterday, and today all the sudden it's not working. Don't know why." So then you call the maintenance people out there, and the maintenance people say, "Okay, well, what's the pump not doing? Why are you calling me?" And when you think about those things, it's actually quite interesting, because we tend to ignore that until it's not doing what it's supposed to do.
Before we can even begin to troubleshoot this, this pump, we got to ask the question, "What is it doing?" And then, of course, later on down the line, if you got a good pump installation, and you've got a suction pressure gauge, and you've got a discharge pressure gauge on the pump, I always ask the question, "What's the pressure?" And, of course, right after that, I'm going to ask you what the gallons per minute and the feet of head are. Because without that information, you have no idea where your pump is hanging out there. I had actually gotten into situations where I've gone to troubleshoot a pump, and the question you see down below, it says, "Is the pump running?" Well, that's kind of a good question. Sometimes at a facility where there's lots of noise going on, everybody just kind of assumes the pump's running. Can I basically tell if the pump's running? How do I tell if the pump's running? Those kinds of scenarios. And then, last but not least, I'm at a whole scenario, "What is the pump pumping?" Most of the times our pumps are there to pump some type of liquid. The definition of that liquid's very important, because the specific gravity will affect things.
The temperature of that fluid will affect things. Things like that can be brought out. Obviously, we have the maintenance personnel hopefully that are looking at this pump know what's going on as far as that. So when we look at our pumps in the pump world, we say, "Okay, what is the pump running? What's the pressure? What's the head? What's the pump pumping?" Be surprised when I ask that question, because everybody goes, "Whoa. I'm pumping water and glycol." Okay. So is it cold water in glycol? Is it hot water in glycol? Temperature of what I'm pumping is very important as well. So, that being said, these are some of the important questions you should ask when you go into doing, "What is my pump doing?" When we get into a pump, what does a pump do? Well, when a pump operates, it performs. First, its centrifugal action creates an area of low pressure at the inlet of the pump, which allows the atmospheric pressure that's on us every day to push that fluid from the reservoir into the inlet of the pump.
