What parts make up the electrical circuits of a water pump motor?

Water pumps or single-phase hydraulic pumps are tools designed to suck or extract water from underground sources or at ground level. And send it, through elevated pipes, through an electrical scheme, going against gravity.

To fulfill their function, they require an electrical circuit. It is for this reason that today we are going to explain about this electrical diagram and how the electrical circuit of the motor of a single-phase water pump is structured ? Thus, you have a notion about what the diagram of the hydraulic pump is like, and how is its installation together with its connection to the power plug.

What are electrical circuits?

Loa electronic circuits or electronic diagram, serve to conduct current through a device or diagram, and give utility to energy. It is necessary, a structure that directs it with precision, such as plugs or light gardens, an electrical circuit is that structure . Through various components, it creates a path for electricity to be conducted from the ground connection of a plug or orchard, to the motor of an electrical device.

In general terms, for the installation of this diagram or electronic schematic of a single-phase water pump. It requires two elements: power source and connection conductor or electronic schematic. The first can be fixed or portable, that is, come from a plug or from a battery.

The second is usually a metallic cable with high electrical conductivity. Interlaced copper wires are commonly used for this task.

Also, other components are added to the circuit depending on its purpose . For example, lamps integrate electrical receivers to transform current into light.

They also usually include switches to control the flow of energy manually. Depending on the complexity of the instrument, the circuit contains more components.

Electrical diagram of a single-phase water pump

The electrical schematic or light diagram graphically represents the structure of each circuit, showing all the components it integrates and their layout. All electrical devices, including single-phase water pumps, have an electrical diagram attached to their cover .

Therefore, it is possible to know how its electrical circuit is formed , at the time of installing the orchards or connections.

What parts make up the electrical circuits of a water pump motor?

Each type of motor uses a different structure or diagram . There are differences in the electrical circuit even between one model of water pump and another. For example, some pumps use a thermomagnetic switch mechanism. While others use traditional mechanical switches, which are manually actuated after installation.

However, all water pumps share the same series of main components , regardless of the additives that they integrate. Next, learn about the parts that make up the electrical circuits of a water pump motor.


What function do they fulfill within the pumping mechanism and how do they interact to form a circuit.

main pump

It is the main part of the circuit, which gives power to the entire mechanism to propel the water. At the same time, it supports the entire internal movement of the water pump . It is composed, by the motor, the drive shaft and the rotor.

Together, these three elements generate the mechanical force to transport the water that reaches the interior of the pump in the direction determined by the user. The mechanical shape of this part can vary a bit but it is always adjusted to its function of moving the liquid.

Inlet and outlet duct

Because the water pump acts as a bridge to carry water from one container to another , it requires two holes: an inlet duct and an outlet duct. Through these cavities, the water flows that the pump sucks in and then pushes out.

The inlet duct is usually in the front connector of the pump, allowing it to be adapted to any piping system installed in the environment to obtain water. Meanwhile, the outlet duct tends to be at the top of the pump so that it can be attached to a hose or other piping system.

suction pipes

They are the external ducts that are connected to the inlet and outlet ducts of the pump. Thanks to the impeller shaft mechanism, it exerts a suction force capable of extracting the liquid and taking it towards the pump rotor. In turn, it leaves the outlet duct with a reverse force to drive the pumping.

Bearings and electric pump

Both bearings and bushings are mechanical parts of the pump that support the drive shaft . Since the shaft is constantly moving and generates a strong vibration, both components give it stability during use.

On the other hand, the electric pump is a special element that differs from motor pumps due to its ability to submerge in water. They have a magnetic float that measures the water level and automatically turns off the pump when there is no liquid flow to prevent it from burning. It is a part that is only present in certain types of water pumps.

Thermostat and valves

The thermostat is also another special part in some water pumps, such as those used in vehicles, to regulate the temperature of the engine and prevent it from overheating due to prolonged use. In turn, the valves help adjust the flow of water, controlling the internal pressure of the water and being able to block the passage of the liquid completely.

How to carry out the electrical installation of a single-phase water pump?

With a very simple process you can install a switching circuit or make a domestic installation for a single-phase water pump. You only need to have the suction pipes or connections, the valves and a universal union .

The connections or electrical diagram must be as close as possible to the pump and avoid passing over its electrical components . Also, the suction pipe should not be inserted too close to the bottom, as it could suck in sediment and become clogged.

Therefore, the installation of the electrical diagram will be wrong and you will have to repeat the process, until you manage to make the connection perfectly. Thus, you will avoid damage to the pipes and the energy diagram of the place where you are going to place the water pump.

Before starting the pump, the priming plug must be removed and filled with water to generate the initial impulse of the rotor. Then it is sealed again. If you want to learn more about electricity, you can download the Electricity Course app from the Google Play Store .
