How Deep Well Submersible Water Pumps Work

Submersion in Water

Deep well submersible pumps are designed to be fully submerged in the water source, allowing them to draw water from significant depths without the need for priming. This submersion also helps in cooling the motor during operation, enhancing the pump’s efficiency and lifespan.

Pressure and Water Flow

As the impeller rotates, it creates a low-pressure zone that draws water into the pump. The water is then forced through the pump housing and up to the surface, providing a continuous flow of water at the desired pressure. The flow rate can be adjusted based on the system’s requirements, ensuring optimal performance.

Automatic Operation and Control

Deep well submersible pumps are equipped with automatic controls that allow for seamless operation without the need for constant monitoring. These controls can include features such as pressure switches, float switches, and integrated pump protection systems. Advanced systems may offer automated adjustments to maintain consistent water flow and pressure.

Components of Deep Well Submersible Water Pumps

Submersible Motor

The submersible motor is the heart of a deep well pump. It is hermetically sealed to prevent water from entering and damaging the internal components. The motor provides the necessary power to drive the impeller and pump water to the surface. The efficiency and durability of the submersible motor are crucial for the long-term performance of the pump.


The impeller creates the centrifugal force needed to push water towards the surface. This component is critical in determining the pump’s flow rate and water supply capacity. The design and material of the impeller can vary, affecting the pump’s efficiency and suitability for different applications.

Pump Housing

The pump housing encases the motor and impeller, providing protection and support for these critical components. It is designed to withstand high pressures and forces exerted during the pumping process. The housing must be robust and resistant to corrosion, especially when used in harsh environments.

Control Box

The control box contains the electrical components necessary to start, stop, and protect the pump. It includes features such as overload protection and voltage regulation to ensure the pump operates safely and efficiently. Advanced control boxes may offer remote monitoring and diagnostics capabilities.

Wiring and Cables

Deep well submersible pumps are connected to the surface control system through specialized wiring and cables designed to withstand submersion in water and provide reliable electrical connections. These cables must be durable and properly insulated to prevent electrical faults.
