Question: :in my farm pipeline is 90mm lenth is 1700 feet and height is (from starting point to end point)50to 60 feet pumpset is 7hp then for which pumpset i buy for beter flow of water for agri in river and which type of valve i use for no comes pressure on pipeline i am a farmer and total land is 10 hector in this place.
Because it is located in the well and under-water, the work described by a submersible well pump is described as "lift" rather than "building pressure". So I'll make a ballpark guess at your friction loss of say 5 gpm or roughly 20 lpm.
Specifics are unavailable, without pulling pump, however, I'm certain pump is 7.5. 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. Measuring the existing system or guessing at the capacity of a replacement pump; 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. And on this same page in our section titled "What is the Pumping Capacity in Gallons per Minute for a Submersible Deep Well Pump?" 
Using an EXAMPLE (This is not necessarily your pump's capacity) you might see a maximum of 7 gpm, On 2021-10-28 at a time from a public source that's 7 miles away - which BTW takes about 7-8 hours to accomplish. 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. Pump can be severely damaged if run dry. Watch out: check the specific pump capacity tables for the manufacturer of the specific pump brand and model you're considering, I have a shallow well ( 25ft ) submersible 1 h.p. What is GPH for 3 HP (10CS30) Gould well pump. The actual effective water flow rate in gallons per minute (GPM) delivered by the water pump through well piping and fittings to the building is typically described as a curve plotting GPM against the pumping head distance in feet, for pumps of various horsepower or pumping capacity. Watch out: be sure that you have an accurate idea of the trouble and costs involved in tripling the well pump horsepower. In such cases, installing a more powerful pump will simply exhaust the well more quickly, leading to loss of water supply entirely. @Jeff, 
Something as simple as a clogged faucet strainer will significantly cut water flow rate there - a problem for which the trouble and expense of changing to a larger horsepower water pump would be very much the wrong "fix". This article includes well pump capacity and model example tables from well pump installation manuals provided by the Water Ace Corporation. Any advice? The idea would be to plug off enough sprinkler heads and 'leaks', in order to reach that 65 psi and run the gun.

A nice example table of Deep Well Submersible Well Pump Capacities is provided in the Water Ace 4-inch (diameter) Submersible Well Pump Installation Manual and excerpted below to illustrate the factors that determine well pump capacity. depth of your well) that is critical. Or see WATER PUMP CAPACITY & GPM FAQs - questions and answers about pump capacity posted originally at the end of this page. 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. @Khanh, and I'm not confident of its heavier duty use over a longer or more regular interval much less over a long pumping distance. On 2021-07-30 We're going to need to look for a commercial gas-powered pump with that capacity. Joyce, Any ideas, @Neal Wittels, MD, 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. Table of Submersible Pump Stages vs HP vs Total Dynamic Head vs. GPM Flow Rate Capacity. Well depth is 140 ft and casing is 4 inches. Based on this info, do you guys suppose that would work or could such high psi pressure ruin the pump? You'll see that you will want the pump model name and model general rating, such as 4" Series V Pump, 10 gpm (catalog p. 32). Jon A cistern is a water-tight container that holds a reserve of water. Will Auto Voltage Regulator help? Model CP6K02,,, Thanks for your help. Virgil, 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. While jet pumps have a pickup placed typically 5 feet above the well bottom, when installing a submersible pump, it is placed ten feet above the well bottom (maximum) or ten feet below the draw down limit for the well. "18 Inch" with perhaps more faded inl numbers below the '60 degree centigrade' mark. 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. What is the PSI for a 3/4 horsepower submersible pump. What will that do to the existing water line. So do read through that material, and don't hesitate to post a status update. Table adapted from Water Ace data cited in detail at the end of this article. How many gallons per hour am I pumping ? 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. - has a total head lift capacity of 121 Feet Control panel stats are as follows, The Water Ace charts (excerpted in part above) make clear that the capacity of a deep well pump to deliver water at a given flow rate varies by the factors we listed previously for both shallow well one line jet pumps and deep well 2-line jet pumps. I purchased a piece of property with a well (120 feet deep, 6 inch casing, 3hp well pump in the well). McDonald Co. Mfg. 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). 2. the pond leakage rate: how much does the water level fall over a specific time period - calculate that volume too 370 volts ac Watch out: the water delivery rate at plumbing fixtures is determined by the water pump as well as building water supply piping and controls. For example, even a pump smaller than yours, say a 5 hp. @chris, a 1 hp. Because the total lift height is so slight (1m) your pump selection will perhaps ignore that. Note: appearance of your Comment below may be delayed: if your comment contains an image, web link, or text that looks to the software as if it might be a web link, your posting will appear after it has been approved by a moderator. What size gas pump/hose combination would I need to achieve a 10, 20 or 30 gpm flow rate. It looks like your pump has a 40 ft. total lift. 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. Finally, the larger pump will deliver a faster water flow rate in liters per minute, but watch out: if the pump rate out of the well exceeds the well's water in-flow rate then you'll pump the well dry. Shiddeshar,The horizontal distance and pipe diameter should not affect the pump requirements unless the friction and other losses (such as from many elbows or bends in piping) are unusually great. The pond evaporation rate On 2020-07-27 by Peeweehenson@charter.Net. @Inspectapedia Com Moderator, Thank You for the information. 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? I think with that pumping rate you're also going to want to take a look at the pump duty cycle. 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. API-Ferguson, Zoeller Pumps, Flint & Walling, Hammelmann Corporation - Headquarters Control panel remained and was used with new pump, strongly suspected to be a Sta Rite. holding tanks locateded near our house. sure just use the on page search box above to find our articles on SUMP PUMPS to see the type of pump you need and several options. Can you weigh in?
IMO if your question is "what GPM water flow rate am I going to get from a new pump" Submersible well pumps are typically offered in horsepower ratings of 1/2 HP, 3/4 HP, 1 HP, and 1 1/2 HP. On 2020-07-27 by (mod) - How far will the pump push the column of water in a 2 inch line? On 2020-08-25 by (mod) - how much water am I pumping out of my well? But it is a number independent of the ability of the well itself to deliver a sustained water flow - the well yield. 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. 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. and you'll see a 7 1/2 hp F&W pump with 23 stages can lift water as much as 700 ft total vertical distance, with a flow rate of about 24 gpm at a 20 psi output pressure. 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. by (mod) We put a 1/3 HP utility pump and it helps, however can any one recommend a pump we can use? - pump horsepower
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: And thank you even though I'm sure it's something of a thankless job, it sure isn't with me. [permission requested]. Typical pressure ranges are 20/40 psi or 30/50 psi. Volts 230,,, three wires, one is ground. Apologies for the delay. Was told I could crank down valves, wait until I reach 65 psi, then measure how fast I fill a 50 gallon barrel and then they could calculate whether or not pump would run that Big Gun under these conditions. and 30psi with some leaks. The well is about 850 ft. and the pump is set about 725 feet. Would the flow with a 1 HP motor be 40 GPM? I am trying to measure the existing system, as we are adding on a new cottage and landscaping. We have no relationship with advertisers, products, or services discussed at this website. Source: adapted from A.Y. Typical residential well pumps range in horsepower from 1/2 HP to about 2 HP. You are increasing the planned total water usage quantity and rate for your property; knowing the well's flow rate and recovery-rate are probably more critical than the well pump's GPM rate.
