Pool Pump Parts

C. Stroup - ONLY ON MY WATCH!

For starters the recent rains had made the grass grow nice and high and the mowing guys, who come bi-monthly, would have their mowing cut out for them.  (Ken mows on the weeks they don’t.)  Two weeks prior, I had to postpone the company that sprays for weeds and fertilizes as they were scheduled to come the same day as the mowers.  Rain had messed with their schedule, too.  You have to leave the yard alone for 24 hours after the spraying in order for the weed killer to work properly and then the fertilizer has to be watered in.  I go into all this detail to let you know what I was dealing with. Two weeks earlier I’d arranged for the tree/shrub trimmer guy to come out on Thursday.  He was supposed to finish in one day.  The job ended up being bigger than he had anticipated so end of day Thursday all the clippings and branches from the trees remained all over the yard.  It took the better half of Friday to finally finish up on the shrubs and while doing so the guys managed to break a pipe down by the well.  Well water is what we use to irrigate, i.e. water the lawn. The break in the pipe was above ground so the guy fixed that with pieces parts we found in my hubby’s workshop.  And coincidentally a second leak appeared and it was coming from underground.  I had to shut the well off until Ken got home and that meant at least another two days of not watering.  I hate to pay good money to have someone come out and fertilize only to have it wasted.  That’s why I was in panic mode over getting the grass watered. These problems would have been quite enough were it not for the pool.  The pump decided to run but not move water.  I did all the things you’re supposed to do to correct that problem; cleaned out the skimmers, made sure nothing was caught in the pool sweeps throat, cleaned out the pump basket, checked for broken hoses, etc, but with no success.  I was afraid the pump was going to burn up so I shut the pool off, as well as the well.  The well has nothing to do with the pool but it started to seem like everything was going awry at once…and they were all water related.  This would mean plumbing for Ken when he got home and plumbing is the thing he dreads most.  This would also mean six trips to Lowe’s instead of three. We spoke on the phone everyday and I would always say things are just fine.  I didn’t want to rain on his parade and spoil the time he was spending with his dad.  Instead I waited until I picked him up at the airport and dumped the bad news on him on the ride home.  Probably not the best idea I’ve ever had but that’s what I did.  He began asking me questions (I knew that would happen immediately) and I knew I wouldn’t be able to answer many of them.  Like for instance, “Where exactly did the pipe break down by the well?”  And, “Are you sure there’s a second underground leak?”  And, “Where did the guy get the parts to fix it?”  (No man likes another man messing with his man stuff.) As things turned out it took one afternoon to fix the well leak.  And it was underground and entirely separate from the pipe that broke upstairs.  Ken had to saw through some big old root from a tree to get to the break but only had to make one trip to Lowe’s.  Imagine that!  The grass all got watered and I just keep telling myself that the five-day delay and all the raking the trimmer guys did didn’t hurt anything. The diagnosis on the pool was that some air was getting in where it didn’t belong and apparently the pump is okay.  However, it’s still not moving water all the time like it should.  I think Ken is fooling himself into believing it doesn’t need to be replaced, but far be it from me to suggest there might still be a problem.  So far he hasn’t had to go to Lowe’s one time to fix it.

Different parts of a Pool Pump

If you have a swimming pool at your home, then you probably would take the time to ensure that it is completely clean at all times. While most people may know that the pool pump is responsible for this function, a number are unsure about how it actually works.

Understanding how the pool pump functions is quite important since it may prove quite useful if the pump ever breaks down. In this way, you can easily buy the replacement parts, if need be, as they can easily identify which part is causing the problem. Understanding how the pool pump works entails learning more on the different component parts of a pool pump .

In general, the pool pump is composed of

- A strainer basket

- A diffuser

- An impeller

- A motor

 all of which are covered by a hard plastic or metal casing to protect it from any environmental hazards such as rain or snow.

- The strainer basket’s main function is to remove debris and dirt from the water as it flows through it. It is worth noting that the strainer basket only functions to remove large pieces of debris and dirt.

- The diffuser functions through collecting water to and from the impeller which is housed within the diffuser.

- The impeller generates a large amount of water pressure through a centrifuge. 

- The motor provides the power which keeps the flow of water circulating through the pump and the pool.

 Basically during the pumping sequence, water flows through the strainer basket to the diffuser and lastly towards the impeller. The impeller functions by maintain a high rotation which throws water out of its outer slots whereby it is later collected by the diffuser. As water accumulates under high pressure within the diffuser, the water is them pushed out through the outer port of the pump back into the pool.

When learning about the different parts of a pool pump, it will be worth noting that the pool pump has two chambers within which each of the listed parts are located. The first chamber lies just before the pull side of the pump, while the second chamber falls just after the push side of the impeller. To keep flow of water moving in the right direction between the different chambers of the pool pump, there are four seals located between these chambers.

The first seal is located at the strainer basket gasket; the second at the diffuser gasket; the third at the housing gasket; and the last seal located at the motor shaft at the end of the pool pump. The diffuser gasket and the housing gasket prove to be quite essential in maintaining the high pressure required to push water out the outer ports of the pump. Furthermore, a poor motor shaft seal will lead to water leaks coming from the bottom of the motor. Moreover, the strainer basket gasket prevents any air from entering the strainer pot. A number of problems come from faulty seals. For instance, a common priming problem may be due to a poor strainer gasket that allows air to be sucked in and thus, prevents the priming action.
