Quick Answer
Expect around 0.5-1.5 gallons per minute (GPM) from a 1 HP submersible pump, depending on the well depth, pump efficiency, and the specific model chosen.
Pump Performance Factors
The performance of a submersible pump is influenced by several factors, including the well’s static water level, the pump’s efficiency, and the flow rate it can achieve at a given head (pressure). A 1 HP submersible pump can achieve a flow rate of around 0.5-1.5 GPM when pumping from a depth of 100-200 feet, but this can vary depending on the pump’s efficiency and the well’s conditions.
Pump Efficiency Considerations
To achieve optimal performance, it’s essential to choose a pump with a high efficiency rating. A pump with a higher efficiency rating can move more water with the same amount of power, resulting in a higher flow rate. Look for pumps with an efficiency rating of at least 50% to ensure you get the best possible performance from your 1 HP submersible pump.
Real-World Examples
For example, a popular 1 HP submersible pump model from a well-known manufacturer can achieve a flow rate of 1.2 GPM at a head of 150 feet. However, this can vary depending on the specific well conditions and the pump’s configuration. To get the best possible performance, it’s essential to consult the pump’s datasheet and consider factors like the well’s static water level, the pump’s efficiency, and the flow rate it can achieve at a given head.
