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

My well pump was replaced recently, so I do a complete teardown and diagnosis on the old pump, including going through how it works. There is one mystery component that I'm not sure about. Is it a temperature sensor? It might be a lightning arrester. Do you know? Leave a comment.
ANSWER: It's a 'biac start switch' which supplies power to the start winding while the motor is starting up, then power is cut when it gets to rated speed. apps.franklin-e...

[@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.

[@cantankerousclankingcontra8295]

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.

[@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. Being on city water we can only experience the deep well pump teardown from guys like you that take the time to film. Thank you sincerely. Lawson di Ransom Canyon

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.

[@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?

[@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

[@RickaramaTrama-lc1ys]

Very interesting and I must say you have a special attitude of which I wish I had. Thanks for the show.

[@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.

[@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.

[@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

[@alaskanken2132]

I hope my well will give me 43 years of service. Great video

[@snoopdogie187]

the well in the house I am in was installed in 1997, so 21 years so far and still going.I wouldn't be surprised if the well pump installed before that one was much older. The disconnect switch / fuse box located near the well pressure tank uses those round fuses, so you can guess how old that setup is.

[@chocolatte6157]

Ken Michael .... 43? Grab the brass ring. Go for 45.

[@oceantrolls7332]

snoopdogie187 great! It is the bearings that fail first. Maybe a good idea to replace them preemptively and you have a longer lasting pump...

[@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.

[@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.

[@------country-boy-------]

[@rogeronslow1498]

Surface pumps can only suck at best 30'.

[@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

[@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.

[@sumilidero]

its AC motor, this is not mosfet, more likely triac if its meant to switch motor

[@kingjames4886]

I'd have called it a transistor... but w.e, probably all basically the same thing.

[@PatIreland]

@@kingjames4886 Probably an off-the-shlef piece with multiple applications, some of which would have req'd more connections

[@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.

[@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.

[@rogerjoesbury9410]

awesome, thanks for taking the time and showing the steps the pump is taking to get water where I needed it!!!!!

[@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

[@wmoran7111]

The motor is made by Franklin electric, your pump looks like a Goulds or Grundfos. That pump looks like its 10-15 years old, definitely not from the 70s lol

[@victoryfirst2878]

@@juggallo42O The pump made in the 70s, the real expensive ones. would last fifty years. How do I know, cause mine was just replaced. Pump guy told me that the new ones never last longer than dozen years. That is called planned obsolescence.

[@TechnicalLee]

Date code is 2005, so it lasted 13 years.

[@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.

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.

[@GeeTrieste]

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

[@pandiyannitt]

Thank you for the explanation...

[@w5cdt]

Thanks for the video...I just replaced my well pump in my 450 foot deep well. 15 psi for every 33 feet of well depth makes my pump output pressure about 200 PSI

Unless you're pumping into an open tank you also add the pressure switch setting and pipe friction as well to end up about 250 psi :-)

Interesting video, Ive always wondered about the inner workings of a pump like that.

[@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!

[@daveb9370]

I believe the temp switch uses a mosfet as a switch. Use very small signal to control a larger voltage.

[@danieljckson]

The white thing is probably the motors "internal thermal protection" (built in overlaod protection) it will open if the motor draws too much current.

[@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.

[@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.

[@TexasCanuck]

That switch you were holding that popped out the inside looks like a Silicon Controlled Rectifier (SCR) they area high current/voltage switch. possibly hooked up to a temp switch and would turn off the motor if overheat.

[@AaronBilger]

[@jorgegb1022]

Excelente conocimiento, pensé en que la repararías, pero no me voy con mal sabor de boca, tengo algo mas en mi cabeza gracias men

[@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.

[@johnwest7228]

those motors are designed to pull water into them from the bottom to help with cooling- the windings are in resin so the water will not cause a short- if the holes at the bottom of the motor become plugged pressure will build up inside, causing the ejection of the parts- the motor died from bad bearings-

[@jnotlog7040]

Hello there folks. Anyone know how we can find our well which is hidden under ice and snow at our new home in the North of Sweden?

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.

I am not a centrifugal pump guru by no means. But all the pumps I have ever worked on always turned with the vanes pulling fluid into the center of the pump, not pushing it out. To me, you explained the pump backwards..... I will do some research on this just to satisfy my curious mind.

Looks like the triac in the escape pod there is, as another commented, a biac switch, as described in the middle of this page: www.franklinwater.com/media/124008/Page-10.pdf Apparently it disconnects the startup winding once the motor gets up to speed.

My well is 600 feet according to above calculating pump pressure my pump pressure would need to be 260psi, sounds too high for my existing pump, going on 20 years now.

[@FarmCraft101]

It depends on where the water level is, not the depth of the well. They may have hit water at 50 or 100', but they continue to drill deeper to get higher flow. But yes, if the water level was actually at 600 feet deep, it would take 260 psi just to get the water to ground level.
