A 3 phase submersible pump is a type of pump that is used in a variety of applications, including irrigation, agriculture, and domestic water supply. These pumps are designed to be submerged in water or other fluids and are typically used in wells or boreholes. In this article, we will discuss the wiring diagram of a 3 phase submersible pump and provide you with a downloadable PDF for easy reference.
What is a 3 Phase Submersible Pump?
A 3 phase submersible pump is a pump that is powered by 3 phase AC power. These pumps are typically used in wells, boreholes, or other applications where a large amount of water needs to be pumped over a long distance. The 3 phase power supply provides a more efficient and stable power source for the pump, which can result in lower operating costs and longer pump life.
3 phase submersible pumps are typically designed to be submerged in water or other fluids, which helps to cool the pump and reduce the risk of damage from overheating.
How Does a 3 Phase Submersible Pump Work?
A 3 phase submersible pump works by using a motor to rotate an impeller inside the pump housing. The rotating impeller creates a vacuum that pulls water into the pump from the well or borehole. The impeller then forces the water out of the pump and through a pipe or other conduit to the point of use.
The 3 phase power supply provides the necessary energy to rotate the motor and drive the impeller. The pump is typically controlled by a switch or other device that turns the pump on and off based on the demand for water.
Wiring Diagram for a 3 Phase Submersible Pump
The wiring diagram for a 3 phase submersible pump can vary depending on the pump manufacturer and the specific model of the pump. However, most 3 phase submersible pumps will have a wiring diagram that includes the following components:
- Motor
- Control Box
- Power Supply
The motor is the main component of the pump that drives the impeller and creates the vacuum that pulls water into the pump. The control box is used to regulate the power supply to the motor and can include features such as overload protection and thermal shut off. The power supply is typically a 3 phase AC power source that provides the necessary energy to operate the pump.
How to Wire a 3 Phase Submersible Pump
Wiring a 3 phase submersible pump can be a complex process that requires some knowledge of electrical wiring and safety procedures. Before attempting to wire a 3 phase submersible pump, it is important to consult the wiring diagram provided by the pump manufacturer and follow all safety precautions.
The following steps provide a general overview of the process for wiring a 3 phase submersible pump:
- Shut off the power supply to the pump.
- Remove the cover from the control box and locate the wiring terminals.
- Refer to the wiring diagram provided by the pump manufacturer and identify the correct wire connections for the motor, control box, and power supply.
- Carefully connect the wires to the appropriate terminals, making sure to follow the wiring diagram and all safety precautions.
- Replace the cover on the control box and turn on the power supply to the pump.

FAQs
What is the difference between a 2 wire and 3 wire submersible pump?
A 2 wire submersible pump has only two wires that connect to the control box, while a 3 wire submersible pump has three wires. The third wire is typically used for a start capacitor or a control box with a built-in capacitor. A 3 wire submersible pump can provide better starting torque and more stable operation than a 2 wire pump.
Can a 3 phase submersible pump be used with a single phase power supply?
No, a 3 phase submersible pump requires a 3 phase AC power supply to operate properly. Attempting to use a single phase power supply can result in damage to the pump, motor, or other components.
What size wire should be used to wire a 3 phase submersible pump?
The size of wire required to wire a 3 phase submersible pump can vary depending on the distance between the pump and the power supply, the current rating of the pump, and other factors. It is important to consult the wiring diagram provided by the pump manufacturer and follow all local electrical codes and regulations.
Can a 3 phase submersible pump be repaired?
Yes, a 3 phase submersible pump can typically be repaired if it is damaged or has stopped working. However, it is important to consult a qualified pump technician or electrician to ensure that the repair is done safely and correctly.
What is the lifespan of a 3 phase submersible pump?
The lifespan of a 3 phase submersible pump can vary depending on the quality of the pump, the operating conditions, and other factors. However, a well-maintained 3 phase submersible pump can provide reliable service for many years.
Can a 3 phase submersible pump be installed by a homeowner?
While it is possible for a homeowner to install a 3 phase submersible pump, it is typically recommended to consult a qualified pump technician or electrician to ensure that the installation is done safely and correctly. The installation process can involve working with high voltage electrical wiring and other hazardous equipment.
In conclusion, a 3 phase submersible pump is an important component for a variety of applications, and proper wiring is essential for safe and reliable operation. By following the wiring diagram provided by the pump manufacturer and consulting with a qualified technician, you can ensure that your pump is installed and wired correctly.
