Generally, the more horsepower your pump has, the deeper it can go underground. More horsepower also increases pressure, allowing you to have a consistent water flow for each fixture of your home, farm or field. Try to find a replacement pump that has a similar or higher horsepower than your existing unit.
An oversized pump will deliver more flow than is required for the system. Depending on the application, it may be necessary to reduce the flow with a throttling valve, or by trimming the impeller.
In some cases, the well pump can be too powerful or strong for the well and consequently pulls sand in from the surrounding aquifer. This sand can cause a rapid deterioration in the pump's valves and cause a build-up of sand at the bottom of the well, which can lead to sand in your water lines.
Note: Never set the cut-off pressure setting above 60 psi.
Pressures higher than 60 psi can damage your pipes, fittings, and switches. This damage can lead to plumbing failure and costly leaks. If the pressure is set at 80 psi, it's very possible the pump will be unable to reach the cut-off pressure.
If the depth of your well is between 25 and 110 feet, you should use a deep well jet pump. If the depth of your well is between 110 and 400 feet, use a four-inch submersible pump.
“Undersizing a progressive cavity pump leads to more problems than oversizing because the volumetric flow is determined by the cavity size, meaning that a smaller pump has to run more quickly to generate the required flow rate, leading to higher wear,” says Seepex Northern Area manager Tim Kaye.
The 1 HP pump operates from depths up to 325 Ft. providing up to a 12 GPM performance. This premium grade pump provides you with long-term peace of mind. Instructions and a quick-start guide are included for your convenience to ensure easy installation and operation for this Zoeller submersible well pump.
The 3/4 HP 2873G-13 submersible well pump provides efficient water delivery from depths of up to 200 ft. All Simer submersible well pumps install into well casings with a 4 in.
Normal well water pressure should fall between 40 and 60 psi, so if your pressure is outside the normal range, adjust the pressure switch.
Typical residential well pumps range in horsepower from 1/2 HP to about 2 HP.
3/4 HP - 1 HP Submersible Sump Pumps
In addition, if you have an installation where you need a high vertical lift or head (20-30 feet) and/or a long horizontal run (150-250 feet), 3/4 - 1 HP pumps provide the additional power needed to pump that water.
Pumps are rated in GPM (gallons per minute). A typical 3- to 4-bedroom home requires 8-12 GPM. When determining your home water needs, add one GPM for every water fixture in your home. Such fixtures include clothes washers, dishwashers, faucets, refrigerators, showers and outdoor water spigots.
Improper inlet conditions are one of the most common reason pumps fail to produce their expect pressure. Inlet issues may also cause ongoing reliability problems. One culprit is air entrainment or lack of prime. It is important to make sure that system is designed so that liquid floods the pump to prime it.
The typical depth of a residential well ranges from 100 feet to 800 feet deep. Some wells are even 1,000 feet or deeper. The deeper a well is, the better the water quality.
Replacing a well pump is something that every homeowner with a private well will need to do at some point. The average lifespan of a well pump is 15-25 years, and you will typically start to notice more issues with your pump as it ages like an increase in repairs, changes in water pressure or increasing utility costs.
This 2 HP pump can run up to 30 spray heads or 20 rotary heads at up to 70 gallons per minute.
A pump that is too big can cause the water lines to hold too much pressure.
Well Pump Sizing
There's no single, set-in-stone right answer, but according to O'Brian, “Well pumps with flow rates between 6 and 12 gallons per minute are generally considered appropriate for most single-family homes.”
Flanges that are too small may cause excess friction, pinching, or squeezing as the nipple is pulled against it. As a result, your nipple or areola could become white or discolored, and you could experience low milk supply or painful milk extraction.
Specifications: Franklin Electric Item Number: 96330740 Horsepower: 3/4 Flow: 10 GPM @ 100' with 50 PSI discharge pressure.
Excluding large, industrial water wells used to supply mines and factories, most water wells contain casings between four and eight inches in diameter. Four to six-inch casings tend to be the most popular for residential and agricultural users.
The best easiest to use deep hand pump well available today is Simple Pump. The unique thing about the Simple pump is that it reduces the pumping effort by half as compared to the other deep well hand pumps. Also, it delivers water from static water level as deep as 300 feet while others are just limited to 200 feet.
