What kind of pump submerged in the well is best for watering the lawn?

Hello.

I have a well (12 circles with a diameter of 1 meter) where the water level is 5 meters (spring and autumn) and 8 meters (summer) below the ground.

I would like to put a pump into the well and use the water discharged from it to water the lawn using a garden hose and a sprinkler like this:



I was browsing the offers of stores and I am confused, because the pumps are different and I do not know which one to buy. Here are some examples that seem fine to my taste:



- maximum water lifting height 8 m, so on the borderline, because one circle protrudes above the ground to a height of 1 meter

Besides, if the switch is deep in the well, how is it turned on? Permanently the switch can be pressed and only the plug can be removed from the socket? Does she keep pumping until it hits the bottom?

The second one I found looks like this:



- water lifting height: 35 m, so much more than the one indicated above and there will be no problems with turning it on.

The third is like this:



Which of these pumps would be most suitable for watering your lawn using well water?

With which technology, theoretically, would I have the highest pressure in my hose?

If I wanted to use a 3/4 "hose, wouldn't it hurt the pump? Specs say 1".

The catalog lifting height does not directly translate into the height / depth of the well. The losses in the water supply hose and the sprinkler itself must be taken into account. The first one has a head that is too low, you need a minimum of 15 m plus the pressure needed for the proper operation of the sprinkler. 1 atmosphere = 10 m water column.

The second ALKO-Jet pump is not a submersible pump, theoretically it should be suitable because its maximum suction depth is 9m, but when the water level drops to -8 plus 1 drain above the level, it will be extremely and may not suck in.

In that case, the submersible pump can probably be rejected, because I do not intend to spend ~ 3000 PLN for this purpose, and I can see that only such pumps have more than 15 m of lifting.

In general, do not look at the head, but at the pump characteristics, because the maximum head means zero water flow - i.e. the pump will raise the water to the given height, but nothing will come out of the hose and the maximum performance is given at zero head - the pump achieves this performance when it pumps water over the same level.

They are also cheaper, depending on the performance you are interested in

You can buy Alkojeta, drill a hole 10 cm above the ground in the lining and pass the suction hose through it, it should be enough.

Added after 18 [minutes]:

See this ALKO product: TDS 1201/4 submersible pump about 700 PLN

There will be no problem with the hole in the circle just above the ground. And with what hose will the water be sucked? 1 "or 3/4"? Besides, what will happen if this type of pump sucks in some foreign body? Does it have a filter, will it break immediately? A total of 2.5 cm in diameter of the hose is not so little.
I found Garden like this:

Its specification:

Therefore, will it be better than the AL-KO Jet 802?

In summer you will not suck, look at the height of the self-priming.
Balance the pump I mentioned above.

At the end of the suction hose, a basket with a check valve is attached to avoid flooding the pump every time it is started. The basket should have a mesh or other protection that will not let foreign objects pass.

I like the AL-KO TDS 1201/4 pump very much. And I'll probably be tempted by it.

Are you writing about something like that?

If you have a covered well, you can do some fixing and permanently attach this pump, e.g. at -1m.

You can also think about an electromagnetic diaphragm pump, e.g .:

Good for filling hen drinkers but not for sprinklers, capacity too low. The cousin has one (he pumps water from -8 m through a 3/4 inch hose, 25 m 2 m up the hill) and the efficiency is very low. Filling the bucket takes approximately 30 seconds.

These pumps are good if someone comes across one of Russian production.

Russian ones are more durable but just as inefficient. The very principle of operation (vibrating diaphragm) limits the efficiency.

Come on, don't talk anymore.

Have you ever connected two or more sprinklers simultaneously on a long cable from a deep well?

I have two such diaphragm products. Russian. They do it, but you can't keep them in the well all the time - the aluminum housing corrodes, not to mention the steel screws that just dissolve. I replaced the screws with stainless ones and I painted the casing with Hammerit and it is better, but for the winter it is better to remove it from the well.

If the use of a similar pump, e.g. eurotec for PLN 85, would work in my well, I do not have water deep, because 3 m including one concrete above the ground, if it is drier, the water will drop a little from 2 meters. At the moment, I have a traditional solution with a bucket and you have to turn your hand. It is a bit of a pain when I have to water the plants, I would like to do something similar to a tap and make a pump switch under my hands as the watering can is full, I turn it off. What do you think, such a pump is enough so that I do not have to stand for half a minute for the bucket to be full ???

Enough, only for the winter you have to take it out of the well.

The well does not freeze, so it should not defrost the pump and you can always submerge it, e.g. a meter under water. How fast do you think it will pump water for these 3-5 meters of lifting? Eurotec from the description has the highest efficiency compared to other similar pumps. Lifting height 82m and capacity 1080l / m

Hello,
When designing irrigation, it is worth doing it from the beginning to the end so that there will be no disappointments:
Every sprinkler (or a group of sprinklers in automatic irrigation) has a range of pressure at which it works and a range of efficiency -> For this, an appropriate pump is selected (giving the appropriate capacity and pressure at the level of sprinkler operation (not the maximum).
The following are not suitable for irrigation:
and) Submersible pumps like this one, for example that do not give the right pressure;
b) Diaphragm pumps like this one which are not suitable for continuous operation and cannot be continuously submerged in water;
Suitable :
and) Submersible peripheral pumps such as this one , rather for small allotments;
b) Submersible screw pumps such as this one , rather for small allotments;
... but the above is not suitable for direct work in a vertebral well.
c) Submersible pumps such as this one ;
d) Submersible pumps for operation in tanks, such as this one ;
e) Single-stage suction pumps such as e.g. ta ;
f) Multistage suction pumps such as e.g. ta .

greetings

What do you need a pump for in winter? You're just going to get me out of the well.

If there is really a risk of damaging the pump, I can pull it out of the well for the winter. Grzegorz Siemienowicz, I will not use the pump for irrigation, but I want to have running water by the well so that I can plug Pompe into the socket and the water will pour itself into the watering can without any effort. Plants grow on a large area, but one bush each and there is no possibility of using sprinklers. I don't know if using a submersible pump is a good idea.

If you want to use the pump only occasionally for a specific purpose and only in the season, I would consider the cheap one peripheral suction pump.

What's the price of this pump? It will be used almost every day, but very briefly because I need a few watering cans. I have a question about the diaphragm pump that I mentioned earlier. In the well, the water is not perfectly clean because there are garbage there or the valves in the diaphragm pump will not hang when they find garbage?

The peripheral suction pump can be purchased below PLN 150.
The diaphragm pump should be removed from the water each time, which in my opinion is acceptable only on plots visited on weekends.
The problem is that both are designed for clean water.
If you want to fill only buckets and watering cans with water that is not very clean, a cheap submersible pump will suffice, it will not generate pressure, but you do not need to fill the buckets. In any other context, it will be better than any other in your case .

Always remove the diaphragm pump from the water

Kuzyn has a diaphragm pump. Sinks in spring, stretches out before winter.

I quoted this from the manuals for some diaphragm pumps.
I also know the common causes of failure of these pumps, which prove it.

Until now, I used a diaphragm pump in the well. Russian seems to be so popular, only 230W.
It is used for watering and filling a small reservoir to water from a watering can in some areas.

The well is 6 meters to the bottom, and the water surface is about 80 cm from the bottom.

The 230W diaphragm pump is not a performance demon. This watering goes down a bit.

The pump broke after 4 years. When correcting the mounting, I saw how it sparked from above and that was where it stopped working. I suspect that the power cord in the housing was torn off, because it was attached to the chain so that it was simply tight, i.e. when the pump was pulled out, someone probably pulled the cable more than once, instead of the chain ...


I analyzed the sense of buying an impeller pump, but I can see that the lifting height fluctuates around 5-6 meters, and it is often a parameter cheated in the specification and overstated. As a result, most of them will probably have a similar performance, or slightly higher, than the diaphragm one, and you have to pay for the rotor from PLN 160 upwards.

You advise gentlemen what to buy.

Initially, I was considering the Garland GBS 750 or GBS 550 rotor. But it's probably not a good idea.

I'm slowly coming to the conclusion that he can buy a membrane one again, but instead of 230W is 300-400W? I just don't know what company.

Today, while in Nomi, I saw such 300W pumps, but the price of PLN 119 POWER UP, and Nomi is usually expensive.

I do not want to pack in expensive pumps because it is only used for watering and filling a water tank the size of a bathtub.

But I've already gone crazy with the amount of these pumps.

I would like to add that this Russian diaphragm pump, due to my aunt's amnesia for such matters, was constantly submerged in a well for 4 years, be it summer or winter.

Well, I like this idea the most, the cheapest pump can be bought at the price of a diaphragm pump and the efficiency is several times higher, which is quite important to me, because standing for a minute by the bucket is a bit onerous, best if it was done fairly quickly. On the Allegro there are many cheap pumps up to PLN 100 with a plastic housing. for 130 you can buy with a cast iron housing for sewage. Are the plastic ones enough ??? And the second thing, every time I want to turn on the pump, the water from the hose will run back into the well and I'll have to wait for the hose to fill up. can it be improved somehow by using a check valve at the pump, what do you think?

I am going to use a check valve myself, because one day I forgot to take the end of the pipe out of the tank and it sucked everything back Not to mention the fact that each time the pump has to fill the hose with water again.

I think that with this "higher" efficiency compared to the membrane one it is a big exaggeration.

Unfortunately, I do not have a point of reference.

As I wrote above, the parameters of lifting height and power are important. Cheap centrifugal pumps often have quite a lot of data, including their power.

I am not convinced that the cheap rotor will be more efficient at, say, 6 meters depth of the well relative to the diaphragm. And especially the rotor pumps around PLN 100, in my opinion, it would be a fiction that would be relatively efficient and durable.

Still some cheap centrifugal pumps have some protection that they will run for 30 minutes and then turn off.

The diaphragm pump is about 1000L / ha, the impeller is about 7000L / ha, and my well is 3 meters more efficient and the difference will be significant.

For example, this one should work with us. And the efficiency is very high. It should also be permanent. http://allegro.pl/pompa-zatapialna-do-wody-brudnej-sciekow-1600w-sit-i3390268336.html
