ECO-WORTHY 24V Well Pump 3.2GPM 4" Stainless Steel, Max Lift 230FT Deep Well Water Pump/Alternative Energy Solar, Well Pump Solar Water Pump

I ha e a problem with this pump will run for few mins very strong pump. However 3 to 4 mins of run time in water that is 50 to 52 degrees Fahrenheit pump shuts off for no apparent reason. I have contacted ted the seller about this problem they were worthless as far as help. I beleive that the thermal switch is faulty or wrong one installed. Seller didnt offer to exchange pump. All they want was pi true of the battery. I can tell u the battery is new with 20 amp solar charger and 350 watt solar panel . Panel can provide 12 to 15 amps of power to the battery. Voltage when pump is running never drops below 12.2 volts . I will be disassembling the pump myself. I will update when I find the problem. Update after disassembling the pump found thermal switch. Must have been sumthg wrong with thermal switch or wrong one put in. The way I found this was I put thermal switch under hair dryer. And thermal switch goes open at 90 farenheit. With no documentation I could fi d what the thermal switch was supposed to be rated for. Took wild guess and got thermal switch for it rated for 300 Fahrenheit. Pump work great.

I installed the pump using direct-connect to a 100 watt solar panel. It ran flawlessly when the sun was shining, for 3 months, then just stopped. I found that the housing was full of water. I contacted the Amazon seller who in turn contacted the manufacturer. I received several emails from the manufacturer over the next month. Most of which, after the first one, were prompted by my follow-up emails to them. I received a replacement in about 1 month with no requirement to pay anything or to return the failed pump. I was happy. Fast forward 30 days, the replacement pump has stopped working. Voltage is good from the panel and there's no water in the housing this time. It simply stopped. I'm going to contact the manufacturer again but I do not recommend this pump, perod. UPDATE: The seller, Fister-US, contacted me. That alone is amazing. They not only provided me with a 3rd pump (2nd replacement), they provided a refund for the trouble. I will return to this review and change it to 5 stars if this new pump last several months. I'm inclined to believe it will if water doesn't leak into tbe housing. I believe the 2nd pump may have died prematurely due to low voltage. The spec sheet that comes with the pump doesn't provide rated operating voltage range. The saller provided me with 20-36 vdc as the range for this 24 volt pump. I foynd reference to tbe pump operating on 12-24 vdc on forums and other reviews. With that being inaccurate, I'm hoping the increased voltage will provide for a longer life of the pump. I'll update this again later.

Let me be clear, this isn't winning any water movement challenges, but for the price and features it works very well. This is for moving water from one location to another location, it is not for pressurizing it for use (sprinkler, faucet, etc). I have a very old surface well on the property (meaning it is rainwater that fitters down into this, so not a underground water reserve) and we use that to pump up water to water the crops, etc. I haven't dug a full well or brought public water to the property yet. Our well is about 60-70' deep and this does the trick. It claims 230', man I would be impressed but am also glad we don't have to go that deep. The further you go up (and marginally over) the harder it gets. At 60-70 feet, I am seeing about 2-3 gallons per minute, so from my perspective that is accurate or a little under the 3.2 they advertise which is probably under ideal situations. I have moved about 100g without it shutting down. I have pulled it up and as far as I can tell there is no abnormal wear, tear, or corrosion. It does pull right about 90 watts, which I've powered three different ways. There are voltage converters / reducers that allow you to plug tool batteries (dewalt, milwaukee, etc) into this type of pump to run them temporarily. Just ensure you pick one that converts the input to about 12v output, which is what this pump requires. This is of course not going to last an incredibly long time, maybe 10-15m max. That is how I started and it does work well. I also have plugged it directly into a standard car battery, which would run an incredibly long time at that wattage. I also have put a 12v power supply that has a 110v AC input on the unit, which again also worked great. So there are a lot of options on how you want to power it, the more tricky situation is determining HOW you want to turn the pump on and off. So overall, I don't expect to pump millions of gallons out of this thing or for it to last decades, but for the use case I have it is very much sufficient. It does the trick, moves the water, hasn't had any performance or mechanical problems, and keeps working as expected. Definitely recommend if you have a specific situation where this would be viable.

This motor is not worth the installation hassle. The first pump was used for 1 season then pulling it back out of the well in the middle of August. This first assembly lasted 1 year and 2 weeks with about 6 months of heavy, every day, summertime usage for the garden. After I learned about the expired warranty position of the manufacture, I disassembled it to find clues for why it failed. The first unit had signs of uneven commutator wear. This uneven wear indicates one side of the commutator winding group was heavily eroded possibly from excessive current, foreign object debris, or misaligned brush contact. I’m not leaning towards bearing misalignment since the clearance tolerance is tight for permanent magnet DC motors. I have not measured the coil resistance on the rotor assembly to determine if coil windings have overheating. I may do that inspection of the circuit resistance if provoked further. The manual has replacement part numbers however nothing on the web site which is a good thing. It prevents you from putting more of your earned money and time into this defective design. After the “unofficial” failure analysis (not through a certified testing facility but more of 20 years engineering experience), I purchased a replacement for this failed pump and it immediately started overload cycling after 2 weeks. That one would cycle with only 50' of head pressure (21.7psi). I tried to replace the original with the exact same model (benefit of the doubt) so now I have experienced 2 failures with the same model number. These canister type pump/motors are designed to fail once the O-ring gasket fails to keep the water out. You get what you pay for with this model. Not recommended for use. Save your money for a better assembly.

I'm using this pump in a 40' well, it feels solidly built and so far it has worked perfectly. I have it controlled by a esp32 based controller with a level switch and it is running for about 3-4 minutes every hour pumping about five gallons, around 100 gallons a day. Hopefully with this usage the pump will last a long time. If your pumping needs are modest then this pump should work well. In my installation voltage drop from the battery to the pump was nearly a volt so be sure to use the biggest gauge wire you can afford. I'm using 10 gauge solid copper. I'm using an extra 100Ahr LiFePo4 battery that can run my installation for a week without sun. All in all so far I'm really happy with the setup. If the pump fails or gives me trouble I'll update this review.

Good

Pumps seem to last about 1 month (~200 hours) for my application. Used pump to circulate water through 500ft of 0.700" diameter poly tube on roof of residence and back into 300 gallon kids inflatable pool. A timer would turn the pump on in the morning and run from 10am to 5pm daily to raise the pool temp from 70f to up to 105f depending on day and solar conditions. There is definitely some sort of thermal cutoff built in as the pump will turn off around 105f for no apparent reason (Voltage was supplied). It will turn on again randomly after about 15 minutes, then cut out again. After about 2 weeks this started happening at lower temperatures and more frequently. I replaced my first pump within the 30 day Amazon period as it's duty cycle had dropped to less than 50% and was unable to heat the kids pool as the best solar gains of the day were being missed. Replaced pump had 100% performance and worked flawlessly for the first two weeks before having the same duty-cycle issues at lower and lower temperatures. The replaced pump now cuts out about every 30 min for about 15 min regardless of temperature. When it works, it works great. The low-flow is perfect for my application. I just wish the cutout issues were addressed. There are defiantly reliably issues as I've had identical failure behaviors twice. The 1-year warranty may be honored (have not tried yet), but I've killed 2 of these with less than 200 hours of runtime each.

I already bought a couple of these (second one as replacement for first one), since they fit perfectly for my shallow well setup. However, both died after around 3 or so months of usage. I used them only a couple of hours most days, but at some point they stopped working. Upon inspecting the motor area (which sits at the bottom) was completely flooded and with traces of sediment. The motor as is, will not turn anymore. The Amazon warranty for return is only one month, I should have suspected it is a product that would have a high rate of return. Edit: It took a good number of messages back and forth, but the vendor finally sent a replacement and a refund for those two pumps. Good. As per some suggestions online, I will use Raspberry Pi logic to only run it for max 5 mins at the time, and let it rest at least 10m (Not suggested by vendor, but by users of similar pumps). My well is very shallow, so it actually helps being constant and let water permeate, rather than fast. I fill several connected barrels with this pump over the day, and then use a bigger pump to push the water to sprinklers all over my property. Thst should extend its life, we will see.
