My dad is re-doing (is that a word?) an old hand dug well. Its probably 75 feet or more deeper and water is at 25 feet down. Instead of going with a jet pump he is considering this- Diaphragm Type Submersible Vibratory Pump Anybody have experiance with these? What is 7bar in the pressure rating? It shows it has a 12mm outlet, thats basicly a 1/2 inch correct?

13MM is just a little under 1/2 in. 12mm is a little under 13MM or between 1/2 & 7/16th in. as far as the pump goes , Never used one we have submersible Jet Punp here for last 10 years , still working (Knocks on wood) :rolleyes:

Re: Well pump?

A bar is 14 PSI so it can max out at 98 PSI<br /><br />but the flow rate is only 2 GPM at 75 ft and there usally not as good as they promise<br /><br />

Re: Well pump?

So what does a typical house pressure flow at, pressure and volume? What are your reccomendations? He seen this and it appeared to be cheap is why he asked me.

Re: Well pump?

KB, if you have no water filtration requirements and no yard irrigation requirements, you could get by with about a constant 8 gpm at 70 psi at ground level.

Nope, its gonna be for there new house. My great grandfather either dug the well or had it dug. They are setting a double wide next to it. It'll have to be filtered since its such a shallow well. I have been looking and I am seeing anywhere from 30-65 psi and 7-15 gpm, depends on what ya wanna pay.

Re: Well pump?

FWIW, the water ace is made by Myers pump out of ashland oh. When installing this unit do not over tighten the discharge pipe as it is possible to crack the composite discharge material which would throw off your performance and cause the system to short cycle thus destroying it in less than one year. Be sure to add a check valve one stick of pipe down from the top of the well. This will help eliminate waterhammer and protect the pump if the floating poppet style check in the pumps discharge fails for whatever reason. As this is a water cooled motor you will need to sleeve the unit in some 4" pvc or the water around the motor will create a heat bloom and overheat the motor and it will kick out on thermal overload and shorten the life of the motor. You want to have the water enter the pipe from the bottom and pass over the motor, thus adequately cooling it. You can use a length of pipe as short as the length of the pump. Notch out the top and tighten down with a progressive screw type hose clamp. A poor mans flow inducer and works just as well as the fancy 200 dollar models. Also put a gate valve on the discharge for fine tuning of the pumps performance. Pumps are sized based on the performance of the well. If the well produces 15 gpm then you can use a pump that produces 1-14gpm. This is where the gate valve comes in. Remember most homes can't handle much more than 12gpm as the plumbing is so small in many of todays modern homes. I would assume but don't know the capasity of your well, but I would guess it to be acceptable with this pump. Just a note, pumps lifespans are rated in cycles not day months or years. If your pump turns on and runs for 5hrs, that is one cycle. If you pump turns on and runs for 10seconds, that too is one cycle. This is why the tank and pump work hand in hand.<br /><br />This is a 3/4hp 10gpm unit which will be exactly what your application requires. It is important that you use at least a 35gal equivalent tank that will provide 10gal of drawdown at a 30-50 pressure setting. This will eliminate short cycling of the motor. Using a smaller tank will reduce the life of the pump substantially. You can purchase a pressure switch preset at 40-60 at any hardware store for under $20.<br /><br />FYI, this is what I sell for a living. If you have any questions along the way please don't hesitate to contact me. Good Luck.

Thanks Pointer, I knew that this is what ya did and was hoping you would chime in. I don't know if he's gonna use his tank off of the cabin or if he's gonna get a new one. The information you've provided is great, I'm gonna pass this on to him. Thanks

Re: Well pump?

No problem. If something comes up let me know. Dug wells are easier to work with and an afternoon should be all this takes.
