Quick Answer
SHALLOW WELL JET PUMPS ARE MORE SUITABLE FOR SHALLOW WELLS BECAUSE THEY REQUIRE LESS LIFT, RESULTING IN GREATER EFFICIENCY AND LESS ENERGY CONSUMPTION. THEY ALSO TEND TO BE LESS EXPENSIVE AND EASIER TO INSTALL THAN DEEP WELL PUMPS. THESE CHARACTERISTICS MAKE THEM IDEAL FOR APPLICATIONS WITH SHALLOW WATER SOURCES.
Choosing the Right Well Depth
When deciding between a shallow well jet pump and a deep well pump, the first consideration is the well depth. Shallow well jet pumps are designed for wells with static water levels (SWL) between 20 and 40 feet below the ground surface. This depth range allows them to operate efficiently, drawing water from the well without the need for extensive piping or complex priming systems.
Technical Considerations
In wells with SWLs below 20 feet, shallow well jet pumps may experience reduced suction pressures, leading to decreased pumping efficiency. Conversely, in wells with SWLs above 40 feet, deep well pumps become a better option due to their ability to handle greater lift pressures. It’s essential to note that some shallow well jet pumps can be modified or paired with additional components to accommodate deeper wells, but this may compromise their overall performance.
System Design and Installation
When selecting a shallow well jet pump, it’s crucial to consider the total dynamic head (TDH) of the system, which includes the well depth, piping elevation, and any additional lift requirements. Proper system design and installation are critical to ensure optimal performance and longevity. A thorough assessment of the well’s geology, pump specifications, and local building codes will help determine the best approach for a specific application.
