Secrets Inside Your Well Pump. How Does A Deep Well Pump Work? FarmCraft101

[@davidmcmillan343]

Thank you for taking both the cost hit of the new submersible pump + the time to disassemble and explain the components of a submersible pump. This has value for many families. Well done.

I run a well pump farm. We usually get them in as Aquarium or more often fountain pumps and then feed them until they are self priming and are ready to move to the deep well pump pool. Most often we'll sell them off at around 120 volts, but some we let go up to 240. Your pump appears to have suffered from pulmonary embolism, which is brought on by filling your pool several times in a row, or throwing a washing machine party. I suggest only feeding your new pump clean watts and avoid any future water parties or late night bucket filling adventures. Pumps work best between 6am and after sunset right before dusk unless you can sneak up on them during noon when they are napping. The part you were inquiring about is a simple proximity sensor. It's looking for other pumps in the general area. Most people think of the well pump as a solitary creature, but they have been known to pair up.

[@lgrieve]

Great video and explanation of a deep well pump.

[@esven9263]

It's probably a triac. When power is applied the bi-metallic strip is in contact so the triac energizes the start winding. As the motor spins up it generates heat which in turn causes the strip to bend and opens the switch. This bypasses the start winding and the motor continues to run on the main winding alone.

[@luisvillalobos6517]

So it's like a start capacitor, without the stored energy?

[@hardushelm6268]

I was also thinking a capacitor

[@tobyoverton_hvacr]

I don't think that's the case, usually these pump systems have a control box at the surface level in the pump house with a potential relay and a start capacitor. I believe the component in question is a thermal overload with a bimetallic switch to cut off power to the motor when it overheats. I suspect the reason he got the OL measurement with an ohmmeter is because this thermal protector had worn out and was not making the connection to the motor windings.

[@hughbo52]

I had to replace a pump motor that was a 2012 unit. The well guys said that could be part of the problem, and if I wanted to save them coming back in the foreseeable future that I should just replace it while they were there. They had one on the truck, a little more horse power, and went with new install. You always wonder about such things, but you have my decision easier to bare. Thanks. Love the fact that you breezed through all the tedious part of screw removal and other time consumers. Good job.

[@zaxarispetixos8728]

Wow. I am so glad I found this. Building a new house and first time I've ever had a well. My curiosity has been through the roof and thanks to you I can sleep without wondering: "how does that skinny pump work down there?" Cheers!

[@notfound379]

Wow, that was great. Loved the mystery ejecting sequence. Everything I take apart, ever since I was 10 years old taught me to expect something under tension to come flying out. It was satisfying to see that rule still holds and I'm well over 60. Anyway, I'll be paying someone to pull my submersible, though I do damn well want to do it myself. "Damn well" ... ha ha get it?

We've got very corrosive salty water on our farm, and we've had to change out a few of those submersible pumps over the years. The pump side was still perfectly fine, its mostly plastic impeller parts, we've learned to just buy a replacement motor and couple it to the existing pump ellement.

You did a good job with your video - it got to the facts without being boring.

[@3daypriest]

My dad had a similar attitude to yours. Well, so far as finding parts and materials to save. Although he was a city boy, he was the first generation city hoy. My granddad grew up in the country and probably still had the understanding broken things weren’t junk, especially living in the country in the early 1900’s. But my dad wasn’t as interested in how things worked. That’s me...also with the salvage gene.

[@HappilyHomicidalHooligan]

3:50 That's a Thermal Overload switch. It cuts power to the motor if the Temperature gets to high preventing damage to the motor. Overheating in well pumps is usually caused by either a bad bearing (starting to seize up) or debris jamming the pump impeller.

[@Sixta16]

Id say unlikely. More likely what Esven stated - some kind of start-relay ding. It is a single phase AC motor. There have to be a start winding with either a run cap or a start relay.

[@bertjetolberg103]

Sorry Guy's sixta is right Motor overheating is controlled by a thermic relay in the power box

[@MarkLawsonY3K]

Nice to see the curiosity, tried to show the kid but really no interest in just learning how things work. To me that is the most fun also.

[@lfmtube]

Very well done and instructive video! I just change my old (220 Volts-3 phase and 3.5hp) deep well pump by a new one in Argentina. The old one it lasts about 10 years of use for the irrigation. I think its burned because some high voltage peak. Thanks to your video, I learned what's inside and how it works. Thanks!

[@Imwright720]

I’ve had stuff like this I’ve fixed but still didn’t use them again. Depending on the difficulty of getting to the part new just makes more sense. I took a pump apart that was drawing to much current and it was just a bearing. The problem is even if I fix it the o-rings would need to be replaced exactly or they would leak. The down times not worth the savings. It can be used somewhere less critical than my water supply. I do what you did, scavenge parts. Lots of stainless nuts and bolts and tid bits for future projects.

[@vintageringsGarry]

I believe switch is a thermal overload protection. The start switch is capacitor and separate magic timer in a box . Just so happens taking my pump out today ( only 8 yrs old) . Sesrching too purchace pump and found your interresting video.i save parts too lol. When your a hobby machinist one becomes a collector to put it gently. Lol

[@TechnicalLee]

Date code on the Franklin motor was April 2005. The pump was an F&W, probably similar vintage. So it lasted 13 years.

[@nomebear]

The rubber and plastic seals cause most of the failures with the pumps. Sand in the bottom of the well can scour the impeller rendering it useless. Even with the long-term wear issues we replaced windmills with submersibles and have not looked back. The maintenance on the submersible electric is nothing like the replacing of leathers and the annual maintenance on older windmills. Plus, the old Aeromotor windmills were worth a good deal of money, people wanted them for their aesthetics which offset the cost of the new elelctric pumps.

[@walt5594]

thank you for showing us. how a pump works.always thinking if motor went out. could you put above ground pump and suck thru old pump???? low cost. ??? my pump getting old and don't want to replace it..thanks for showing how it works.

[@dj7356vnt]

is it just me or does no part of that reflect 70's tech. not sure a mosfet would have been utilized in that era pump as well as the multi stage abs impeller pump. i've been wrong before but something just doesn't add up here.

[@blahfasel2000]

As far as I could find the TO-220 package was specified in 1987, so yeah, definitely not 1970s.

[@johnwest7228]

Franklin electric motors have a date included in the serial number at the top of the motor casing, just above the label

[@ThreePhaseHigh]

Devon Hickmott I think you’re absolutely right. Too bad he didn’t mention who manufactured the thing . That information would’ve been really helpful.

[@djblackarrow]

About the temeperature thing... I think it's a Bi-Metal switch, connected to the Triac (Triacs are used to switch AC Power, MOSFET's can only switch DC). But i don't know why there are 3 Connection-Pins. Eventually this connections are Live, Neutral and the switched one, who is connectet to the Motor.

[@Live.Vibe.Lasers]

[@Funkyourdauter]

i work for a well water supply and water treatment system wholesale company i deliver Franklin pumps to well drillers daily and i can say they hold up pretty good too.

[@richgrant3312]

Its an internal submersible pump thermal, if your panel that runs your pump may have landings for wires from the pump. If three phase power wires would be black, red, white, seals would be orange and red, thermals would be black and white. The seal and thermal wires would be smaller gauge wire. I'm guessing this is a single phase with no pump seals or thermal besides the internal one to the pump which would act like a hair dryer when tripped it will take time to cool and remake the path of electricity a closed circuit again . Just my thoughts with working with submersible sewage pumps. I'm guessing as well that the pumps turn off and on by a up stream pressure sensor if the sensor senses psi is below 60 psi the well pump turns on. Great channel keep up the good work.

[@GeeTrieste]

The pump having an integrated check valve, does there need to be another check valve at the expansion tank?

[@GUSftw]

the pump could be seeing 100+ psi depending on the depth of your well system. that's why this design is required. the pressure required to push water that high is way more than a single impeller pump can provide. i just had another one fail today. we can't seem to get more than a few years out of these pumps for some reason.

[@ronaldcourcy9999]

Try not opening the fill valve completly. If you open the valve maybe a third it seems to increase the pump life.

[@brensdengaming3217]

I work on water Wells it's awesome you took it apart and were interested pretty cool

[@sushilgharat2264]

Thanks for the video.. I faced problem in my submersible pump.(1hp) I checked resistance in motor found ok. Further checked found pump electric panel card fault. So replaced the card now works fine..

[@pumpdoctor6117]

That switch is the mechanism that disconnects the start winding and energizes the running windings. The motor is supposed is filled with clean water with a bit of non hazardous anti-freeze so they don't freeze and burst open in a warehouse or building somewhere. The top "rubber part" is not a main seal and can be gone and still function. It is called a sand slinger. Helps to keep sand away from the top bearing. The swelling inside causing the rotor to be locked and not turn is most likely due to a power surge and swelled the windings. Seen it many times. I was hollering at the video saying the liquid end screws on. The liquid end was probably OK, though very few installers any more will just replace the motor only like we used to do 30 years ago. The liquid end will usually pump in excess of 100#'s in order to push water up the well and still create cut off pressure on the switch above ground. It takes 1500 degrees to turn the epoxy to sand and free the copper. Cost more to get a furnace to that temp than what it is worth unless you have a huge amount of motors.

[@FarmCraft101]

Good info. Thanks, and thanks for watching.

[@fredgeitner713]

Pump Doctor It's not hard to see why those pumps are so expensive.

[@johnpike9612]

Lol....I was going to say that you could've just replaced the motor to save some money had you not cut open the pump. The problem with that is we don't do it because franklin and the other various manufacturers will not warranty the motor unless we also buy the pump and controller, there are still some of us who know how to REALLY repair pumps. We just can't because of the red tape crap.

[@AntiqueClive]

I just did an identical set up. Our system is 3phsse 415v motor. I have to replace the impeller pump end (not the motor) every 12 months as it gets clogged with muddy silt from our old borehole and the flow to our storage tank dwindles. I also cut one open but could not quite grasp the magic of how the plastic discs worked!

[@mytube8630]

Maybe consider raising pump ( reduce depth) a few yards , could be too close to the bottom . Or install plastic 5inch liners the full depth , obviously slotted.

[@gustavoguti27]

Interesting. Used to have troubles with one of these pumps. After just 7 months of use it was causing the terminal switch from my house to cut the power (don't know the correct terminology in English). Everytime it was plugged, instantly power was cut off. An electrician installed it without the terminal protection, directly to my house service connection and worked. Had to buy a new one, never knew why it did that

[@Bacnow]

I would love to see a side-by-side tear-down of a new pump vs that old pump!

[@bertjetolberg103]

It would be exactly the same I sell pedrollo and DAB pumps they all have the same dimensions and for a 100 bucks extra you can have them with a Franklin motor This pump was not broken all he had to do was buy a new motor

[@willykanos1044]

The hose clamps are there to connect the pump assembly to a plastic hose. The hose also carries the weight of the pump and is subject to its starting torque. Many submersible pumps are hung on 1" galvanized pipe. If your pump has been in there for forty years, hanging on plastic pipe I would worry about the plastic. Ask the people who put you new pump in.

[@sstroh08]

willy kanos In my area at least, no pump is on galvanized unless someone does it themselves. Galvanized makes is extremely heavy and would be a nightmare pulling. Most have flexible 100 psi plastic clamp pipe. The pipe isn't supposed to be what holds the weight either. There is supposed to be a rope that ties to the pump that ties up top that holds its weight.

[@brianbrehmeyer3929]

I used "well strength" (thick walled) plastic pipe and hung the pump from it. (I think there are 3 grades of rolled plastic pipe. Well pipe being the strongest.) Nylon rope is slightly longer than the pipe and is only there in case the pipe breaks. My pump has been down there since 1981. My well is 96' deep. I think somewhere around 200 or 300 feet they start using steel pipe. I know of one household well in Bend, OR that is over 700 feet and is steel all the way down. He has had to call in professionals to pull the pump twice. Several thousand dollars every time. (Wandered around KZbin, found out my information on well piping is somewhat inaccurate. Though I disagree with the presenter's opinion of poly pipe he shows all the options: kzbin.info/www/bejne/jXe1qKOHjNSNqM0 )

[@johnpike9612]

Last month I pulled a well with the seamless poly pipe (first time I've seen it here) that was set at 500'. Plastic is better than galvanized for long term, galvanized rusts plastic wont. Most of them around here use threaded pvc, schedule 40 (standard pvc wall thickness) down to 200' and schedule 80 if it's deeper than that

[@johnpike9612]

Oh btw, if it's been in there 40 yrs it doesn't matter what they used, it should be replaced with new stuff

[@zaxarispetixos8728]

willy kanos if it hangs o In the water you did something wrong the pumps always must be on something stable

[@sysghost]

my wild guess on the FET thing that popped out is that it's not temperature, but a motor start. Once the motor is up to speed, it'll disengage the start winding.

[@whatevernamegoeshere3644]

What was the part number on the TO-220 mosfet looking thing? Could have just been a BT### series triac from the way it is wired. The bimetallic strip heats up, disconnects, and that disconnect only happens at a few miliamps, leaving the heavy duty beefy switching to the silicon. That way your heat sensor contacts will not wear out ever. Edit: I was almost right, it was only for the start winding.

[@daddydawg1902]

I had a Deep well Put in in the late '90s and made the mistake of going cheap on the pump with a 'rebuilt' one @ 1/2 Price of New (rebuilt was $400). Total cost of the well was $1400. After SIX Months I started getting an Inline Filter i put in clogged with what looked like small particles of MUD and sent filter to the Locally owned company to examine. They said SILT that would eventually clear.. so I went with replacing the filters every Other DAY. Finally after over Two WEEKS and my Plumbing starting to clog too... I took another clogged filter to another drilling Company to inspect. They (Two Man Company) told me it was PLASTIC (ABS?) . That the Impeller was breaking down. They came out.. replaced the pump (@ $800) with a Stainless Steel Impeller and NEVER had a problem since . BOTH Companies were in business over FORTY Years but the First I used was Two 20-something BROTHERS.. (They took over from aging Grandfather... always arguing..very Unprofessional and NEVER Returned calls when I was asking for assistance. The second was The owner and his hired help ..very Professional and knowledgeable. Saving Money NOW... MAY cost you MORE Later. I got what I paid for with the first!

[@nickmcginley4570]

Simply stated, a centrifugal pump works by throwing water against the sides of the space the impellor is in, and the only place for it to go is out the top. That space is usually called a bowl, and on some of them, it is bowl shaped. The motor and hence the impellor is spinning very fast, so it is being thrown very hard.

[@blewfish]

What year was on the label ? It seems newer than 1972.

[@keithlincoln1309]

Any chance you remember the rpm on that pump? Those backwards curved impellers require very high rpm to move their intended liquid or vapour.

Very informative. Question - after watching the well company install the new pump - would you think it could be a DIY project to replace one? Thanks for the video -- I've wondered exactly how these pumps are structured. We have a 30+ year old pump, I've been considering replacing it before it fails, its about 500' deep. One would hate to reach SHTF and then have the well become inop. Even under normal conditions it would be a problem, being without until the well company could do an install. PARTS is PARTS..... You think like I do,... what can I salvage for parts -- LOL!! Most recent video on our channel was about salvaging a multifunction printer - amazing how many useful parts, numerous SS rods, dozens of useful springs, etc. And the cost, if I had to buy those parts separately would be well above $100, ...from a broken printer that originally cost about $50.

[@zaxarispetixos8728]

RelentlessHomesteading disconect the power and the tube and start pulling up then connect it back and go

[@RelentlessHomesteading]

That sure 'sounds' easy enough. The weight of 550 feet of 5 large electrical cable (wt of 5 x 500' spools of #8 copper wire) + steel cable + water line + pump - would be very substantial; requiring me to build up some large pulley mechanisms and winching on the front of my tractor FEL. The time required for me to build that up would likely offset any gains from DIY. And there could be some little tricks or details that I would miss doing it for a first time. The cost of any kind of screwup would be very high - so it may make sense to just hire this one out, and spend the time on my day job to pay for it.

[@zaxarispetixos8728]

RelentlessHomesteading the easiest thing you can do to pull it up is build a metal stracture that can support the weight of a pulley and start pulling the chain so the pump goes up and the worst thing you can do is dropping the pump or hit the cable of the new pump on rock or something if you make a hole in the insolation and water goes in the pump it will be badly damaged also also make sure to buy the exact same pump with the right filters, power make sure that the new pump is siting on stable ground and it is not floating in the water

[@tl7209]

that thing popping out of it made my day. probably the contact cant handle the current draw of the motor so the mosfat is used to turn the motor on and off with the signal of the contact switch

[@kingjames4886]

probably, not sure why you'd need 3 external contacts for that though.

[@Milosz_Ostrow]

Although MOSFETs first appeared in 1948, there were no MOSFETs in 1972 with the reliability, current carrying capacity and voltage rating to be useful in a well pump application.

[@wyngaart1]

The temperature sensor with the mosfet; Not sure, but I think the temperature sensor switches off the mosfet. The motor windings are connected to the mosfet, so when the mosfet is turned off the motor is turned off to prevent it from burning the windings. I think this becouse you just have two wires to connect the pump as you explane. So there must be done something inside the pump with the temperature/mosfet sensor and the motor windings.

thank you, much better info than pump diagrams from the pump suppliers and makers.

[@melneeds6358]

Great video. This comment (question) might seem silly, but I have been wondering---- if I have a submersible pump 50 ft from my house and 110 feet deep, is it possible to plumb a hand pump (valved off of course) into my main water line in my house for use if electricity is off. After your interesting tear down of a submersible pump do you feel it is possible to hand pump water up through the submersible pump, or is there something in the pump that would prevent this?

[@hackupboulders]

Good question. He must not be monitoring his video.

[@davidschwartz5127]

I had what looks to be the same model of Franklin deep well pump go bad on me 5 years after installation in 1977, the electrical connector on the motor shorted out from water leaking in somehow.

[@jtg2259]

mine went out in May, 165 ft down it lasted 15 years. Got a 1hp replacement and that thing cost me $850 for just the pump and $300 to pull the well and put the new one back down.

[@senorjp21]

I think the TO-220 package might be a triac for switching AC current - like a mosfet but capable of switching AC

[@khadijagwen]

You had lots of service. Be thankful.

[@Prairiedrifter1]

Nice, I’ve been wondering how one of these works and seeing the insides is a plus!!

[@cleaner10399]

had one of those at the farm i worked at, 85 feet down, pulled it to change the pump cause the check valve failed. put in the new pump and added a check valve to the old one. two years later swapped out the newer pump cause the motor burned out.

[@turbo3089]

Would it be possible to generate electricity simply by flipping the deep well pump upside down

[@Blantston]

One of the biggest issues with failed submersible pumps is the installation of a piece of crap like the one you disassembled. The motor is a Franklin Electric product ( no issue with their motors ). The wet end however ( pump ) is a dumpster. Proper sizing and overall system design greatly improves longevity of the pump and motor. Power quality, frequency of starts, motor cooling, motor controls and water quality all factor into the performance and reliability of any system. As soon as I saw the composite discharge adapter I had my doubts. Hopefully a professional grade replacement was installed in its place.

The plug w/3 wires is for the start and run compasitor. U have a 2 wire pump. A3 wire pump has start and run located above ground. (I prefer this type, easy to service.

[@palmrose2]

Franklin two wire motors are split phase, and don't use capacitors.

[@tigerseye73]

The switch contacts would be normally closed when the motor is stopped. When the pressure switch at the tank closes, current flows through the small contacts to energize the start winding in the stator assembly. As the motor accelerates the small contacts open and remain so untill the motor decellerates to a stop. The start winding is what provides the initial torque in the proper direction.Without it the motor would just growl and cook its stator winding, or posibly even begin rotateing in the wrong direction. The video doesn't clearly show the wireing path from the watertight connector plug to the stator switch, but I am sure you do not have a mosfet transistor there. The simple and rugged AC motor would have no need for such. It is definately part of the power circuit, but my guess would be a fuse unit.

[@kenl5217]

Really cool stuff. What made the biac switch just pop out?

[@FarmCraft101]

Lol. Don't know. Must have been some residual pressure from pumping?

[@ganeshrvgk]

I am from Coimbatore, India and we manufacture millions of pumps every year. Every 5 years the pump goes bad and we need to call them to fix it. So the pump company charges us $350 ~ 400 in total for labor and new pump. But you get the refurbished pump for half of that price.

[@pandiyannitt]

Thank you for the explanation...

[@aeugbeshe]

Can a 1kva stabilizer be used to bust the voltage for 0.75hp pump?

[@ManuelRamirez-dq7cv]

Thanks for the tutorial!!! I do have a question,if the pump is incased in a stainless steel cover,why is it rusted?

[@meyou245]

Maybe cheap stainless, or it was just minerals/iron in the water rusting?

[@andrewbowers3676]

The sensor in there looks lie ka hall effect sensor, it probably senses the rotation of the motor/pump and cuts power if the motor doesn't spin up, and may or may not also incorporate a temperature sensor.

[@eslandafreeman4821]

how much did you pay to change a pump? labor and pump?

[@007vsMagua]

When was this pump design invented? Amazing technology! Great lesson, thank you.

[@Gaudwin1]

The knowledge and work it took to invent and produce these mechanical gadgets amaze me.

[@zaxarispetixos8728]

The thing you took out is not a temperature sensor if you put a pump you must put a thermic protector that cuts off the power if the pump is getting more amps than it should and it heats up

[@Neceros]

How do they pump water in space?

[@AnatoFIN]

Has been in the well from 1972, so 46 years. Yeah... In general you might be able to fix it, but how long it will last?

[@get-the-lead-out.4593]

I inherited my grandparent's house. They had the well pump replaced back in 1982 and just last year it finally broke and so lasted 36 years. The new owner of the same business who previously replaced the pump said the average consumer will NEVER get a well pump like they use to make. Now they are only made to last approx 15 years, most commonly come with only a 10 year warranty, and you're EXTREMELY lucky if they last 20 years... by reducing the quality of pumps, keeps businesses like theirs in business by being guaranteed to come back in 10-15 years!

[@palmrose2]

Bla bla bla. I'm a pump guy. Franklin hasn't changed their motors, except where they are manufactured. Mexico. Pump companies have changed things to sell @ a lower price point. I mostly sell F&W domestic submersible pumps. Their Commander series. The most expensive, but 100% made in the USA. Even their motors. I'm in my fifties and healthy. I figure that any new pump I install should be good for the rest of my life, assuming the rest of the system is kept in good working order.

[@PatIreland]

Actually, it is not built-to-fail but rather not-built-to-last. Nowadays, people want cheap, so they force manufacturers to cheapen all the components- saving a few pennies here and a few pennies there- then you get a 10 yr motor for %10 cheaper than a 30-yr motor. And the purchaser "saves money."

[@sunshine7453]

It is fun and educational open up a fail pump. Thank you!

[@danginther2795]

Well done, quite interesting.

[@heronimousbrapson863]

Does the pump pump water into a pressure tank?

[@FarmCraft101]

Yep.

[@TurboDieselFury]

Interesting autopsy!!! Thanks.

[@wolfc70]

Nice Homart fan under the workbench!

[@kokopelli314]

Looks like a P channel FET cuts power to windings when thermocouple makes contact between source and gate.
