A 1 horsepower (hp) well pump is a pump used to extract water from a well. The depth that a 1 hp well pump can reach depends on several factors, including the size of the well, the type of pump, the discharge capacity of the pump, and the static water level in the well.
There are two main types of well pumps: shallow well jet pumps and submersible pumps. Shallow well jet pumps are designed to extract water from wells with a static water level that is less than 25 feet below the ground surface. These pumps are installed above ground and use a jet of water to create suction that draws water from the well and into the pump. Shallow well jet pumps are typically less expensive than submersible pumps and are capable of pumping water from depths of around 25 feet.
Submersible pumps, on the other hand, are designed to be fully immersed in water and are used to extract water from wells with a deeper static water level. Submersible pumps come in a variety of sizes and capacities, and they can pump water from depths of up to around 300 feet. A 1 hp submersible pump is capable of pumping water from depths of around 150 to 300 feet, depending on the specific conditions of the well and the pump.
In addition to the type of pump, the size of the well also plays a role in determining how deep a 1 hp well pump can go. The larger the well, the more water it is capable of holding, and the deeper a pump can reach. In general, a well that is 4 inches in diameter is capable of holding enough water to support a 1 hp pump, while a well that is 6 inches in diameter or larger can support a pump with a higher horsepower rating.
The discharge capacity of the pump is another important factor that determines how deep a 1 hp well pump can go. The discharge capacity refers to the amount of water that the pump is capable of pumping per minute, and it is measured in gallons per minute (GPM). A pump with a high discharge capacity will be able to pump more water from a well in a shorter amount of time, and it will be able to reach deeper water levels.
Finally, the static water level in the well also plays a role in determining how deep a 1 hp well pump can go. The static water level is the depth of the water in the well when the pump is not running, and it is a function of the rate of water replenishment in the well and the rate of water extraction. If the static water level is deep, a pump with a high discharge capacity will be required to reach the water, while a pump with a lower discharge capacity will be sufficient for a well with a shallow static water level.
In conclusion, the depth that a 1 hp well pump can reach depends on a variety of factors, including the size of the well, the type of pump, the discharge capacity of the pump, and the static water level in the well. A 1 hp submersible pump is capable of pumping water from depths of around 150 to 300 feet, while shallow well jet pumps can reach water levels of up to around 25 feet. It is important to consult a professional well installer or pump specialist to determine the appropriate pump for your well and to ensure that it is installed and operated properly.
