Try the search box just below, or if you prefer, post a question or comment in the Comments box below and we will respond promptly. Based on this info, do you guys suppose that would work or could such high psi pressure ruin the pump? you really need to know the well's flow rate since it doesn't matter how fantastic a pump's capacity is if it pumps the well dry. by inspectapedia.com.moderator (mod).

To read this chart, follow the 300 Head horizontal line in the chart across from where it crosses the 4 GPM line on the 1/2 HP pump curve over further to the right to see the 1 1/2 HP pump (two models) touching or close to the 300 Head Resistance line at 7 GPM. I purchased a piece of property with a well (120 feet deep, 6 inch casing, 3hp well pump in the well).
Watch out: however as you'll see in our pump capacity tables on this page, the pump's output varies a lot by pump model, even when the horsepower and all other factors remain the same.

And thank you even though I'm sure it's something of a thankless job, it sure isn't with me.
by inspectapedia.com.moderator (mod), @Allen, Measuring the existing system or guessing at the capacity of a replacement pump;
Take a look in the article above on this page and you'll see a table of typical well pump capacities that map
In sum, I'd want to have a more accurate description of the water flow problem in your building and of the causes of any poor water flow complaints before hopping to install a new larger well pump.
You'll see that when you plot pump HP and lift against GPM capacity the results are plotted in curves, not a straight-line linear function such as your example would suggest.
Table adapted from Water Ace data cited in detail at the end of this article.
So, the question is, is there enough information here, to determine if this pump is capable of running a 'Big Gun Sprinkler Head', that requires 65 psi to operate? I lost my prime from a water line I installed charged 800 feet from the pump location which the pump is lower then the water level usually but air must have got up the line somehow, So I just checked and I have a 11 foot lift then 400 feet of travel kinda level then the remaining 400 feet is down a gradually sloped bank so I usually have 10 psi gravity feed at the pump location the other day the hose burst at the pressure side of the pump I replaced the hose and now the pump will not pressure up to 60 psi any more it acts like it is running out of water at the pump I have a check valve on the pressure side so the pressure tank holds water but the pump looses its water somehow, So I now have the back water valve, as well as a foot valve on the suction side and the pressure tank on the pressure side and it seems to no longer be able to pressure up like it used to the pump runs and runs my flow meter shows that around 50 psi pressure it stops flowing so I have just been turning the pressure down until the pump shuts off but I have now turned the pressure down twice so I assume I should just get a new pump?
Because some pump models are capable of developing internal pressures of more than 100 psi, if your building piping, pressure relief valves, safety controls, wiring, and plumbing are not properly installed, very dangerous conditions including electrical shock, tank explosion, and leaks or floods can occur.
Pump had been replaced years earlier,without any manuals available, receipts and the like. In selecting a well pump, the well depth as well as water flow requirements must be considered.
The table include depths to five hundred feet. Readers of this document should also see the water pump types described and our other diagnostic guides for water pumps, wells, motors listed in the "More Reading" section below. Hi

Probably just about a minute or possibly even less.
On 2020-11-01 Table of Submersible Pump Stages vs HP vs Total Dynamic Head vs. GPM Flow Rate Capacity. Any two-line jet pump or submersible pump - see the pump lift capacity and gpm tables in the article above, Chris. A one-line jet pump can typically raise water from depths of just a few feet (or "0" depth) to about 25 feet in depth.
The pond fill-rate: how much water enters the pond, from what source, when? @Jeff,
InspectAPedia tolerates no conflicts of interest.
The Water Ace charts (shown in part above) make clear that the capacity of a one-line shallow well jet pump to deliver water at a given flow rate varies by these factors: Permission requested, Water Ace Corp. Aug 2010 - Pentair Pump Group. Because the total lift height is so slight (1m) your pump selection will perhaps ignore that.
- How long can a lancaster sumersible deep well 3/4 hp pump run without water, Robert:
Those are discussed in the articles I've recommended. Then find the pump capacity table for your specific well pump brand, type, and model and you'll see its rated output capacity in gph or gpm.
From there you can do the math. You need to read the specific pump flow characteristics for the specific brand and model and type (above ground 2 line jet pump, 1 line jet pump, submersible pump) of the same voltage; BobBe sure that you set the water pressure tank AIR pre-charge to 2 psi below the pressure control switch CUT IN pressure setting, AND that the pre-charge is done with the pump off and all water pressure relieved from the system. Because some pump models are capable of developing internal pressures of more than 100 psi, if your building piping, pressure relief valves, safety controls, wiring, and plumbing are not properly installed, very dangerous conditions including electrical shock, tank explosion, and leaks or floods can occur.
For example a brand A 1hp well pump with a 50 foot total lift and all other piping details identical, pump 50 gpm while another pump brand B 1hp well pump with the same lift and piping details might pump 40 gpm.
Watch out: in some cases of a poor flow-rate well, it is the well's recovery rate or flow rate that limits the water flow rate at the building (unless a large buffer storage tank of water is also installed). On 2020-06-21 by (mod) - what size submersible pump do I need?

For submersible well pumps, typically higher HP pumps also are designed with a greater number of pumping stages - mechanical impellers that increase the lift capacity of the pump. Virgil, We need to get specific. So you add together the height of the hill PLUS the depth of the well from which water has to be lifted. The water usage rate for all sources: home use and other uses. many numbers faded at this point, but, "RPM 3450", PH 1 Single phase, Recapping, calculations of required water pump size consider: Watch out: none of the topics listed in your message or in pump GPM capacity above address the potentially controlling effects on water flow rate at a given fixture caused by in-building piping, valves, clogs, etc. For example, at 70 gpm, 2" ID Sch 40 PVC pipe has a friction loss of 3.71 gpm. Volts 230,,, three wires, one is ground.
- gpm of water delivered. Water pump lift can be defined as the force required to overcome the "head pressure" measured in feet.
There are certainly portable gas powered water pumps like the Honda WX10TA that can pump at higher rates (that model claims 32 gpm)
by Inspectapedia Com Moderator. Hop over to our admired Engineering Toolbox at www.engineeringtoolbox.com/pumping-water-horsepower-d_753.html Actual pump capacities vary by model, manufacturer, design, and installation details. But it is a number independent of the ability of the well itself to deliver a sustained water flow - the well yield.

How long will it take to fill the house tank?
Two-line jet pumps intended for deep well use and made by other manufacturers can be expected to have similar capacities. A nice example table of Deep Well 2-Line Jet Pump Capacities for 1/2 hp and 1 hp deep well pumps is provided in the Water Ace Jet Pump Installation Manual and excerpted above & below to illustrate the factors that determine well pump capacity. In the article above, we show tables and charts helpful in determining the required size in HP required for a water pump in a given installation. Beyond that point, It's not just the pump horsepower that is important to get water lifted 60 feet from a water source.
You can see in the chart that changing from a 1/2 HP to a 1 1/2 HP well pump, if we stay at the same pumping head resistance and using a 300 ft. head resistance example, we would see a theoretical GPM flow rate change from 4 GPM up to around 7 GPM if all other factors remained the same. In the submersible pump capacity table you can see that the table considers: Water Ace asserts that a typical 3-4 bedroom home requires a water delivery rate of 8-12 GPM. Instead, I am achieving 60 GPM and the well itself is only producing 50 GPM thus the pump is out pumping the well and the pump saver is repeatedly stopping and starting the pump. But you can get a GENERAL answer comparing well pump GPM capacities from tables given above on this page. we have a 7and half hp submersible pump pumping through a 4 in line . In such cases, installing a more powerful pump will simply exhaust the well more quickly, leading to loss of water supply entirely. Submersible.
Look at transfer pumps and irrigation pumps.
CAUTION: DO NOT run pump dry. To accurately compute head pressure, expressed as Total Dynamic Head or TDH, the designer adds the pumping level or height that water is moved inside the well, the additional vertical rise from water top to final destination, and the friction losses in the piping system.
To have any more information, would require removal of pump. The two shallow well pump capacity charts above & below are for one-line jet pumps produced by Water Ace. I live in Gillispie County in Texas and have a stock pond that has a slow leak. Original well pump was 1-1/2 HP with a flow of 60 GPM.
Well depth is 140 ft and casing is 4 inches. API-Ferguson, Zoeller Pumps, Flint & Walling, Hammelmann Corporation - Headquarters
Submersible well pumps are typically offered in horsepower ratings of 1/2 HP, 3/4 HP, 1 HP, and 1 1/2 HP. The well pump also needs to be matched against the lift required - how far water must be lifted from the bottom of the submersible pump in the well to the water pressure tank and controls in the building. I understand that the 3 hp well pump will need 9kw power source to drive the pump.
I have 1HP deep well pump that cannot run continuously due to sudden decrease in power supply (230 volts to 115 volts when pump starts running).
Indeed, B.K., the flow rate through piping is affected by more than the pump output pressure.
Bottom-line: we're not so concerned with how quickly the two tanks get filled as the alternative is hauling fresh water 200 gal. Rated water flow rates for pumps range (by horsepower and model) from a nominal 6 gpm to 35 gpm.

We have a outlet outside, and we submerge the pump in the drain. However, we've also considered using a submersible electric pump to fill the holding tanks rather than a gas powered pump.We have decent flow to our house from a 200' deep alkaline well located appx.
IMO if your question is "what GPM water flow rate am I going to get from a new pump" You'd think maybe so, but no, not really. 1-Line jet pumps intended for shallow well use and made by other manufacturers can be expected to have similar capacities.
The idea would be to plug off enough sprinkler heads and 'leaks', in order to reach that 65 psi and run the gun.

You need to ID the specific pump brand and model as well as the total lift height to be able to get the pump's output rate in GPM at a specific height.
@Khanh, So any pump sized to give 500 lpm with low-lift requirement ought to work.
On the page above you will see a colored line chart with pump capacity curves that go to & beyond the depth in your example, please take a look at
Most water pump manufacturers provide lift capacity curves for their particular water pumps, plotting horsepower and flow rate and lift height as shown in our example chart above. Thank you. Water table remains at 15 feet at all times.
That's 4% of the LPM flow rate that you want - probably not significant.

Using an EXAMPLE (This is not necessarily your pump's capacity) you might see a maximum of 7 gpm, On 2021-10-28
Unfortunately, the well company does not have records from 25 years ago on the 1 HP pump they installed.
I can only answer in general concept that a larger driven point will generally get better water flow if the surrounding water table can support it.
Typical pressure ranges are 20/40 psi or 30/50 psi.
so there's no single "right" answer. and I'm not confident of its heavier duty use over a longer or more regular interval much less over a long pumping distance.

I need to pump water from a river that is 500' horizontal plus 100' vertical from two 600 gal. then you need to know well depth or / and total lift height, and
A change from a smaller 1/2 hp pump to a 1 1/2 hp model may require electrical wiring changes of wire size or gauge and possibly a change from 120V to 240V service along with appropriate changes in pump controls and switches - all adding to the cost of installation of the new pump.

Question:
range can deliver 35 gpm, and at 40 psi discharge pressure, the same pump will deliver about 30 gpm. Thanks for your help. You'll see in the pump output capacity tables we give on this page that you need to specify a few more parameters, such as the desired delivery pressure. switch is set at 30 psi on and 50 psi off.
Any advice?
@Wade I.,
You need to specify the pipe material and also the number of bends or elbows.
Keep in mind that it is the lift, not the horizontal distance, that is the hardest work that the pump has to do, so it's the pump depth (probably something less than the 120ft. Yes, in general,
Thanks for the assistance If a gas powered pump could deliver 10 gpm that would suffice. But we don't know the rate of water flow into the soil around your well point. There is a tremendous number of portable, gas-powered water pumps, some of very high capacity, some used for transfer, for trash liquids, and for fire-fighting (higher delivery pressure, smaller diameter hose); a 1 hp submersible well pump - varying by model - can deliver 23 gpm at 40 foot lift, down to 14 gpm if that same pump has to lift water from greater depth. On 2020-08-14 by (mod) pump loses power and can't keep running, The pump wiring is under-sized for the length of run. McDonald Co. Mfg. Runs a wheel line system, with 33 heads.

you'll see that a typical 1hp submersible pump with a 20 ft. lift with an average of 40 psi output might pump around 40 gpm. 370 volts ac This pump, at 1.5hp (not necessarily your model) at 30 ft. is pumping around 13 gpm.
Unless a well pump is protected by one or more special devices to prevent the pump from running without water flowing through it, the pump can be damaged or destroyed.
On 2020-07-26 by (mod) - how high a hill can we pump over with a 7 hp pump? 30psi with some leaks. What you can infer is that you are tripling the pump horsepower - which is a big jump, so it would be reasonable to expect a significantly increased water flow rate - all other components being equal.

We're going to need to look for a commercial gas-powered pump with that capacity. @David, So we're still not quite comparing actual pump specifications. Fair question but we have no data at all that would let us tell you how much water you can take out of your stock pond each week:
So I'll make a ballpark guess at your friction loss of say 5 gpm or roughly 20 lpm.
1. the volume of the pond (if it's a rectangle that's easy, if it's like most ponds, bowl shaped, you'll have to either make detailed measurements or calculate the rectangular volume and then guess it's half that Am told, 'with leaks fixed' psi would reach around 45psi.

We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. What size gas pump/hose combination would I need to achieve a 10, 20 or 30 gpm flow rate. A 70 meter deep (230 ft deep) well can be served by a 2 hp.
For your present circumstance I would consider either installing a suitable pressure tank to stop the short cycling problem Or having a conversation with technical support at the manufacturer to see if they will permit Control that will vary the pump speed and output.

It is also the type of pump. Currently I have a 1/2 hp water pump that will pump 100 gal in 15 min.
Joyce, the distance from the well to the tank is 100 meters. I think if you're watching the pump pressure and you don't let it get much above 65 PSI you're not going to destroy the pump during the test. - pump lift height (or depth)
Sure we have some very clear diagnostics for the problem you described, found in the article with tank at 18 psi.
a fixed answer would be mere arm-waving speculation. Apologies for the delay.
Typical shallow well jet pumps sport water delivery rates from 4 gpm or 15 liters per minute (lpm) up to as much as 25 gpm (95 lpm) depending on the variables we list below the well pump capacity tables shown. Or use the SEARCH BOX found below to Ask a Question or Search InspectApedia. If you can get power to the pumping site, I'd look at a submersible pump that can deliver water perhaps at a slower rate but as you suggest, over a longer interval, filling storage tanks. and holding tanks locateded near our house. or 1 1/4" ID from well to pressure tank and pump), but also
I'll see what I can find. I was looking at a 1 HP models, but can't find a good one. review again: pipe material

We have no relationship with advertisers, products, or services discussed at this website.
It's worth noting that across manufacturers a number of pumps use Honda engines,. As we don't know any of that data, nor the well piping diameter of your installation, its length, bends, etc. In addition to the table above, the following page will give more details on how to determine submersible pump size: As best I can answer: the horizontal pumping distance that your pump can push water doesn't drop to zero, but rather the longer the piping the slower the pumping output rate will be in gpm.
For example, even a pump smaller than yours, say a 5 hp.
Would the flow with a 1 HP motor be 40 GPM?

House has 1000 Gallon storage tank. If your cistern were 10 ft deep and 6 ft. in diameter and round, it would hold about 282 cubic feet of water. Watch out: the water delivery rate at plumbing fixtures is determined by the water pump as well as building water supply piping and controls. Watch Out: Safety warnings are throughout any pump manufacturer's instructions.
