Sure it's informative to measure flow rate at the well, but that's not telling us what the pump's original rating data were. I have a Franklin motors1.5 horsepower pump at 30 feet deep with a 2-inch line. 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. - gpm of water delivered. 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. 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). 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. Below are some submersible pump design stages and horsepower ratings: The data in this table is for example purposes. Apologies for the delay. Jon Beyond that point, It's not just the pump horsepower that is important to get water lifted 60 feet from a water source. Currently I have a 1/2 hp water pump that will pump 100 gal in 15 min. Sure we have some very clear diagnostics for the problem you described, found in the article
Submersible. 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. I was told by my well tester that the 1 1/2HP pump with a 35 GPM wet end would give me 42 or 43 GPM which is what I want. On 2020-08-24 by (mod) - what's the gpm from a Franklin 1.5 horsepower pump at 30 feet with a 2-inch line. 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. A two-line jet pump can typically raise water from depths of 30 feet to 80 feet, and at water delivery rates of 4 gpm (for a 1/2 hp 2-line jet pump serving an 80 foot deep well) to 16 gpm (for a 1 hp 2-line jet pump serving a 30 foot deep well). 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 the WX10-TA shown here comes with a 16 foot hose Serial 1D77 (April, 1977) But this existing pump was replaced in early 1990's with one that works with this control panel 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. 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. Watch Out: Safety warnings are throughout any pump manufacturer's instructions. 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. Would going from a 1 1/4" to a 2" point and pipe delivery likely offer any effective improvement. Control panel remained and was used with new pump, strongly suspected to be a Sta Rite. 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. In such cases, installing a more powerful pump will simply exhaust the well more quickly, leading to loss of water supply entirely. Because the total lift height is so slight (1m) your pump selection will perhaps ignore that. or 1 1/4" ID from well to pressure tank and pump), but also We have sharpened the text and provided a larger, more legible table (click to enlarge) than the original. 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. 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). On 2020-08-25 by (mod) - how much water am I pumping out of my well? Thank you. 30psi with some leaks. On 2020-07-27 by (mod) - How far will the pump push the column of water in a 2 inch line? On 2020-07-26 by (mod) - how high a hill can we pump over with a 7 hp pump? I cannot get the pump to run unless it runs 22 psi on to 68 psi off. Bottom-line: we're not so concerned with how quickly the two tanks get filled as the alternative is hauling fresh water 200 gal. See this catalog that gives pump capacity tables for Franklin Electric's submersible pumps: FPS SUBMERSIBLE PUMPS, RESIDENTIAL, LIGHT COMMERCIAL CATALOG [PDF]. of course. It's at a level of about 4 feet and covers about 1/4 of an acre. 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. submersible, will have an output rate that might fall from 43 gpm to 4 gpm if it has to face a total lift of 700 ft. On 2020-07-26 by (mod) Total lift capacity of a 7 hp water pump? 2" pipe to the house up a hill 300' 10% incline. Control panel stats are as follows, But you can get a GENERAL answer comparing well pump GPM capacities from tables given above on this page. And thank you even though I'm sure it's something of a thankless job, it sure isn't with me. how high a hill can it go over? How far will the pump push the column of water in a 2 inch line? pump sucking from about 20ft deep. I replaced a 2HP submersible pump with a 1 1/2HP submersible pump with a 35 GPM wet end hoping to achieve about 43 GPM because the 2HP pump was delivering 60 GPM which is more than I want. I think with that pumping rate you're also going to want to take a look at the pump duty cycle. 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. Water pump lift can be defined as the force required to overcome the "head pressure" measured in feet. Nobody can give a completely accurate answer to your question as you pose it because we don't know the pumping capacity of your pump in gpm - though you might get close to that by identifying the pump brand and model and then checking it's owner's manual. Any two-line jet pump or submersible pump - see the pump lift capacity and gpm tables in the article above, Chris. submersible well pump - varying by model - can deliver 10 gph while lifting water from a 200 ft. deep well. Runs a wheel line system, with 33 heads. 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. Am told, 'with leaks fixed' psi would reach around 45psi. The effect of the height to which your pump has to lift water is to reduce the pump's output rate; it won't fall to zero except in extreme cases. Typical pressure ranges are 20/40 psi or 30/50 psi. 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. I think that the ability to vary pump output is different across Brands and models. So a silting in very old sand point wells flow can't be improved with a higher horsepower pump. 400' horizontal and 80' below our house, by way of a submersible. You need to specify the pipe material and also the number of bends or elbows. Shallow cistern 10' deep. 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. a 1 hp. 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. @Allen, 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. What will that do to the existing water line. To get to a 20 psi discharge pressure a typical submersible in the 3 hp.

Watch out: check the specific pump capacity tables for the manufacturer of the specific pump brand and model you're considering, House has 1000 Gallon storage tank. Watch out: the water delivery rate at plumbing fixtures is determined by the water pump as well as building water supply piping and controls. From there you can do the math.
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.

@Jeff, The Water Ace charts (shown in part above) make clear that the capacity of a deep well pump to deliver water at a given flow rate varies by pretty much the same factors as those we listed for shallow wells and well pumps. 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. What problem are we solving here? HP. On 2020-07-27 by Peeweehenson@charter.Net. I'm just a little nervous about even trying that, obviously I would not want to ruin the pump and am not certain of the earlier test suggestion. A two line jet pump of the same horsepower will have no trouble lifting water 60 feet. We put a 1/3 HP utility pump and it helps, however can any one recommend a pump we can use? They suggested disconnecting the water line from the well to the house (they used some other term for this), and just filling 5 gal buckets straight from the well, and see how long it takes to fill them. There are certainly portable gas powered water pumps like the Honda WX10TA that can pump at higher rates (that model claims 32 gpm)
