Single 24v 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.

Für meine Zwecke zuwenig Druck.

Ottimo prodotto.

Dura poco con la extraccion al 100 % ( 15 minutos ), disminuye su presion de extraccion, posible se acabe el agua del pozo y su recuperacioin sea mas lenta que la rapidez de la bomba. Estoy monitoreando. a los 10 dias fallo totalmente, la saque y salio sin la carcasa despues del anillo de absorciion.. Solicito su intervencion para su reposicion tiene seguro.

Questa è la seconda che compro.....e non perché l'altra ha smesso di funzionare, ma perché funzionano benissimo e ho deciso di usarla anche per un altra applicazione. Mi ha svoltato la vita..... Niente più benzina o gestori Enel per movimentare l'acqua.

La bomba solar funciona muy bien, me está subiendo el agua alrededor de 60 metros , con poco caudal claro. Pero es un flujo continuo durante todas las horas solares. En 8/10 días me llena la balsa de unos 25000 litros. El único defecto por corregir algo es la salida del agua de la bomba que es a presión, debería de ser de rosca. En mi caso que tiene que subir el agua a mucha altura 60 mts a veces se sale la manguera del cuerpo de la bomba, pero en cuanto a funcionamiento todo muy bien
