Quick Answer
Submersible pumps generally outperform jet pumps, especially in deep wells, due to their ability to handle higher pressures and temperatures. Jet pumps are more suitable for shallow wells with a high water table. This is because jet pumps rely on atmospheric pressure to push water up.
Choosing the Right Pump Type
When selecting between submersible and jet pumps for a deep well, the primary consideration is the well’s depth and water table height. For wells exceeding 200 feet in depth, submersible pumps are generally a better choice. These pumps are completely submerged in the water, eliminating the need for a pipe connection to the surface.
Submersible Pump Performance
Submersible pumps can handle pressures up to 500 feet of head, while jet pumps typically top out at 150 feet. This makes submersible pumps more suitable for deep wells with a low water table. For example, if you have a 250-foot well with a water table at 200 feet, a submersible pump can efficiently pump water up to the surface.
Jet Pump Limitations
Jet pumps, on the other hand, rely on atmospheric pressure to push water up the pipe. This means they require a minimum of 20-30 feet of water table height to operate effectively. In deep wells with a low water table, jet pumps may struggle to maintain sufficient suction, resulting in reduced performance and potentially leading to pump failure.
