do pool pump impellers wear outdo pool pump impellers wear out

Pool Pump Gaskets. If you water was dirty and you ran that water through the filter, the filter may need to be cleaned several times to clear the fine debris out of the filter. Pool pumps can develop a range of different problems over time, such as a faulty bearing, poor air flow around the motor, or even a clogged filter. Corrosion usually occurs due to an excessively low pH, usually around 2.0-3.0, which is very acidic. For maximum safety turn off the power at the circuit breaker to the motor - usually located next to the timer box. Again your pump should maintain prime. Silicon pool lube can help seal both. Keep track of the washers. When the system is activated, the motor will begin pumping water from the well and into the homes plumbing system. Replace the four bolts evenly. I was wondering if the pump could be losing flow when the back pressure in the filter starts to increase due to problem with the impeller. You should also make sure to check the pool pumps manual for specific recommendations on settings or other factors to consider when running the pump. Even with the pump basket in place, very small debris can pass through the pump basket, and clog the impeller. How We Fix It At this point, we have 2 options. In most cases, for example, a rag is sucked into the impeller inlet, the power would decrease for the reasons I explained earlieras the flow drops a lot, so does the pressure. Give us a call and we will line you up with a technician at the pump manufacturer. Due to possible hand injury, I dont think anyone would recommend trying this procedure. If you have low filter pressure, cant hear the motor pump, or hear strange noises coming from your pump, you most likely have a clogged pool pump impeller. He may be reached at drpump@pumpingmachinery.com. The pump basket is in place to prevent small debris from entering the volute, and possibly clogging the impeller. In your September 2016 article What Happens to Power and Efficiency when a Pump Wears Out, which I really enjoyed, you mention that the data on power can tell the difference between the types of internal wearfor example, if the wear ring clearances have worn out or if the impeller itself is deteriorating (as might be the case with highly abrasive pumpage or corrosive chemicals). I have thought about this and believe that wear that affects the impeller only (and not wear ring clearances or other leak paths) would result in: with the decreased pump power being the difference in comparison to the results shown in your paper. ds1 - If you have a leak between the impeller and motor, you probably have a bad motor shaft seal. Then check all your suction connections. Posted: 8/4/2014, Ken But I don't know. With the wrench securing the back end of the motor shaft, screw the impeller back onto the shaft (clockwise). But in many cases, tight clearance parts, such as wear rings and bushings, are the first to wear. Pool pumps should generally not make loud or intrusive noises, as they should run rather quietly while they are in operation. I do not believe it is the filters one is 6 months old and it does the same thing. Generally, it is much better to set up a timer or program the pool pump to run on a regular cycle, in order to give the pool cleaning and filter system ample time to work, while also limiting the amount of energy being used. Thank you for the GREAT information and video. HygienePool - That's a long time for an impeller. Hello there! Finally, make sure to regularly perform basic maintenance for your pump, such as checking the oil levels, seals, bearings, and impellers to prevent additional noise caused by inefficient operation. This is a huge benefit for anyone who has to access pump components such as bearings, wear rings, impeller, and shaft seal. First, turn off the pumps power source and remove the pump from the pool. As they don't have any support either side they tend to be weaker, and therefore are typically used in smaller, inexpensive pumps that aren't operated under significant strain. Enter a postal code to find the nearest Hayward authorized pool professional. The seal looks different than the one I took off. Pool pump motors are continuous-duty outdoor rated motors, but they will eventually wear out and break down. Fairbanks Nijhuis also delivers professional services including installation, maintenance, repair, and training. You might feel the screwdriver or coat hanger dislodging the debris and even see that material come to the bottom of the pump. Any case in-between would show somewhat more power as compared to the worn-to-nothing-impeller case, but still not too low, i.e., below the original power curve. Changes in pressure inside the pump turn the liquid into vapor and, as the pump's impellers spin, back to liquid again. Thanks! If you notice your pool pump's output not being as strong as usual, it could be a sign that the impeller needs replacing. Is it necessary to pry the motor away? www.pumpingmachinery.com/pump_school/pump_school.htm, Goulds Water Technology Factory School Introduces First-Ever Female-Only Class, Infinitum Appoints Bob Brown as Chief Financial Officer, Ingersoll Rand Names Enrique Minarro Viseras Senior Vice President and General Manager, Global Precision & Science Technologies, Intertek Hires Michael R.

Posted: 1/4/2013, mckyd68 We dont build the motor, but I believe it is a three phase, induction motor. If there's coolant leaking from the weep hole, that's your early warning. TIP: Each horsepower motor is matched to a slightly different sized impeller, with a different part number. A dirty pool pump impeller will restrict water flow both in the basket and pool, so you can tell the difference. This means you must be aware of anything like pine needles, seeds, sand, grass clippings, and pool plaster particles. Over time, those gaskets wear out and become dry and brittle, allowing the coolant inside to leak out. To explain further, if the impeller is completely plugged, or worn to nothing, there would be zero flow and zero pressure generation, yet there would be still some power read on the electric meter because the pump still consumes power on rubs of the bearings, seals and other mechanical losses. So, in that example, the power would be small, but still not zero. I believe it is about 16 years old. Share this: What do you think about this observation: I broughtup the case of a clogged/plugged pump, and you confirmedthat a completely plugged pump would generate zero flow and zero pressure but would still consume some power due to mechanical losses.. Diffuser Gasket - Found on the cone . If bolts were numbered 1 though 4, replace bolts in this sequence - 1, 3, 2, 4 - to ensure that the motor is set properly inside the housing. Additionally, water that enters the system can corrode the bearing components and cause them to breakdown. If the above methods do not completely satisfy your desired outcome, then using a variable-speed pump or adding a external acoustic enclosure to reduce noise levels may be beneficial. My pump ran dry due to my pool running low on water and now it has very low pressure, will replacing the impeller be the fix I need to regain the pressure I need to filter the water? wayneb56 - I wouldn't think you could prevent a motor from spinning by holding the impeller. Once you get the impeller spinning smoothly and arent pulling up more debris, you can put the pump basket back in place. If there is excessive swelling, noticeable wear and/or cracks, or one or more of the impeller vanes have broken off, replace the impeller pump immediately. If there are any cracks or pieces broken off on the impeller, it needs to be replaced. Experiencing low pump pressure. One method to reduce the noise your water feature makes is to add more plants and rocks to the area. Impeller wear rings are small plastic rings (10) that protect a misaligned impeller from rubbing, and must be installed before placing the Diffuser. My Hayward super pump loses its prime when I attach the pool vacuum at the skimmer. When a pool pump impeller begins to wear out, it can become noisy, cause the pump to lose pressure, or it can become clogged altogether. Ready to get that pump fixed? Again DO NOT touch the bearing surface of the seal. For instructions on replacing this seal click. And if your impeller was clogged, you would not have good flow initially. But now, in your example, the pump curve for the system does not change, just the impeller curve changedit went down in pressure because of the increased hydraulic losses due to either rust-up or blockage (more friction in the impeller passages). Sounds like something is binding your impeller when everything is assembled. To clean your pump basket, you first turn off the pumps power. If you believe it is a wiring problem, I'd call an electrician. I did not bother to calculate this exactly, but if you take any pump curve example from any catalog, you can easily recreate this with actual numbers. Required fields are marked *. Add the rest of your hoses without attaching the cleaner. instructions for how to enable JavaScript in your web browser, Please click here to view our How A Pool Pump Works HTG, Please click here to view our How ToRemove Stubborn Pool Pump Impellers Blog, Please click here to view our How To Replace a Motor Shaft Seal Guide, Please clickhere to our main pump parts page, Please click here to view O Ring Lubricant. Check hose connections then take out one hose at a time to try to isolate the leak. To remove the impeller you will twist the impeller off in a counter clockwise motion. Without one, your pump will likely jam or break. Apply a thin coat of lithium- or high-temperature grease to the bearing surfaces and the shaft before reassembling them. Sometimes its possible to clear the impeller by spinning it by hand while down siphoning water from the filter. It can corrode the surface. Yes, pool pump impellers do wear out over time. Postal Code: How far from the above postal code do you want to search? ), I focused on the rings issue, not the impeller per se. For more information, visit www.pumpingmachinery.com/pump_school/pump_school.htm. Posted: 2/20/2017, InyoPools Product Specialist Dennis R. If the bolt or socket is stripped, you may have a problem getting it to hold when you reassemble your pump. These are prone to clogging especially if you notice a lot of debris. Then the impeller should then be visible. Place a 7/16" wrench on the flat end of the motor shaft to secure the shaft from rotating. Hydraulic Institutes addresses maintenance strategies for use on pumps. Check the top of the basket cavity to make sure it has not cracked from over tightening. Posted: 4/21/2022, InyoPools Product Specialist Matt S. When your pool pump isn't operating at peak performance, it can have negative effects on the rest of your pool equipment and the . Impeller Wear Wear in the pump impeller often shows up as low readings on the filter pressure gauge. the flow starts slowing down about 2 hours after the pump is restarted. Then pulled off putty in sequence to see what connection generated air in the system. Yes, it is possible to slow down a pool pump. To check for bearing noise associated with a water pump, you will want to start the vehicle while it is stationary and start the engine at idle. Both flow and head decreased significantlya lot of friction. Try hitting around the joint with a rubber hammer. Doch der Post scheint weniger ein Aprilscherz zu sein, als eine neue Marketing-Strategie. You should also check if the washer, nuts, and bolts of the impeller are loose or worn out. Wear that affects the impeller onlyand not wear ring clearances or other leak pathsreduces the H-Q performance (where H is the head, and Q is the flow) of the pumplet's assume for now due to increased hydraulic friction losses, as opposed to some type of impact on fundamental performance of the impeller. You may have 115V at the breaker box and your pump may be set up for 230V. By: Author Olin Wade (Remodel or Move Stuff). It's happened to every pool tech who has been working for a while. If the rotation speed is minimal then the bearings are most likely worn out. However, practically speaking, I think it is unlikely that whatever material is plugging the pump would not also get into the rotating surfaces (for example, radial bearings) and thus increase the mechanical losses, which would result in an increase in bhp. My question is how best do I separate my old leaking shaft seal (and impeller) from its metal bracket/motor mount. See our guide on cleaning out an impeller Also if you have low pressure, you may have developed a suction leak in your pump or in the piping coming into your pump. Since the H-Q performance reduces,the intersection with the system curve will change resulting in a decreased system flow. Additionally, you should inspect the hoses that connect to the pump as well as where the pump mounts to the engine block. There is a difference in the effect of the pump curves between the wear of just the rings versus just the impeller (or a clogged impeller as you noted alternatively). A clogged impeller does not cause not all pressure and pump issues. You can generally find your pool pump capacitor(s) on the pool pump, at the side or top of the pump. Running the pump dry, failure to perform regular filter cleaning or necessary repairs, and improper water balance can all lead to premature motor failure. Radius: miles. Let me know. Most people replace the motor when the bearings go but they can also be replaced with the right tooling.

Now youll be able to use the screwdriver, coat hanger, or even needle nose pliers to remove the debris from the impeller. Water will spray out initally as you see the pressure on the pressure gauge go to 0 psi. The impeller is a critical part of the pump, as it helps to pull water from the pool and forces it through the filtration system. Motors and impellers have two total horsepower scales, uprate and full rate. There are primarily two main styles of ANSI pump impellers. The air bubbles move, pressure is increased and the air . Pull the assembly apart from the housing. This article discusses the operation and operational assessment/management of pumps and how to deal with the operational problems of pumps. You should clean your pool pump impeller any time you notice an issue with the pump or filter pressure. Remove the pump lid and check the basket. Keep working the impeller back and forth until its easier to move. Then check the impeller shaft and seal plate for any wear that would offset your shaft seal. Placing plants and rocks around and as close as possible to the water feature will help to muffle the sound of the water flowing. Pool pumps located in areas of extreme weather conditions may have a shorter lifespan. Check the inlet and outlet valves to ensure they are open and free of obstructions. Pool is not covered. Lets dive in. This type of wear and tear occurs if the pump has been switched on and off regularly. The earlier you catch these warning signs, the better, as it will save you more money in the long run the sooner you notice it! Essentially the bhp curve for the pump is unchanged. Replace lid. Well walk you through how to check your pool pump for red flags it needs pool pump service. Yes, pumps are made to function outside and will get wet from the weather with no real problems. Pumps. If the humming noise is louder than expected, then it is likely that there is a problem that needs to be addressed. Pumps designed to handle "chunky" liquids typically possess flexible impellers that can bend as they encounter solids. If necessary, replace with new bearings. Dehydrated pump. Posted: 4/22/2022, Claudia L. Duncan I'm ordering parts to replace an impeller on its way out for a Hayward Max Flo II, I'm not sure which diffuser gasket to order.
