What is an automatic water pump and how does it work?

An automatic water pump is a device that automatically turns the water pump on and off. It works by measuring water pressure and activates the pump when the pressure reaches the desired level. Once the water pressure reaches its maximum, the pump is turned off. This ensures that the water pump doesn’t run continuously, which helps extend its lifespan. An automatic water pump is a valuable investment for anyone using a water pump. This device can help you save both water and energy. In the following, we will discuss its benefits and applications further, so stay with us until the end of this article from Tavantak.

What is an automatic water pump?

An automatic water pump is a device used to control and protect the water pump. This device turns the pump on or off based on the water pressure or flow in the pipe. Automatic pumps come in both mechanical and digital types. For example, after purchasing a 1-horsepower water pump from Tavan Tak, you can also use an automatic pump.

A mechanical automatic pump (pressure switch) consists of a spring and two electrical contacts. The spring is compressed by the water pressure, and when the pressure reaches a certain level, the contacts open, and the pump turns off. When the water pressure drops, the spring expands, the contacts close, and the pump turns on.

A digital automatic pump (set control) consists of an electronic board and a pressure sensor. The pressure sensor measures the water pressure in the pipe and sends the data to the electronic board. The electronic board turns the pump on or off based on the received water pressure.

The types of automatic water pump

An automatic water pump is a device that turns the pump on or off based on the water pressure or flow in the pipe. This device is generally divided into two main categories:

  1. Pressure Switch: This is the simplest and oldest type of automatic pump. The device works by adjusting the water pressure at the location of the switch using a spring and a pressure gauge. With frequent switching of the pump, the pressure switch tries to maintain the pressure within the desired range.

  2. Set Control: This is the newest and most advanced type of automatic pump. The device operates using a pressure sensor and water flow, automatically turning the pump on or off. Set controls offer many advantages over pressure switches.

The automatic water pump is an essential device for supplying and distributing water in agricultural irrigation systems, building water supply systems, and similar applications. Due to its important role in maintaining water pressure and regulating water flow, it must be selected carefully based on specific needs.

To choose the most suitable type, consider the following:

  • Type of Water Pump: The type of water pump you are using (such as a surface or submersible pump) can determine the most appropriate type of automatic pump to use.

  • Building Height: If your building is very tall or has many floors, a set control is more suitable as these devices adjust pressure intelligently.

  • Water Consumption: The amount of water you need is also important. If you require more precise pressure control, consider using a set control.

  • Budget: Based on your available budget, you can choose between a pressure switch and a set control. Pressure switches are less expensive but offer limited adjustments.

The advantages of using an automatic water pump

An automatic water pump or pressure control unit is an electronic device responsible for controlling water pressure and flow. This device automatically turns the water pump on and off to maintain the water pressure within an optimal range in the water supply system. By purchasing a domestic sump pump and installing an automatic pump, many benefits can be gained.

The advantages of using an automatic water pump include:

  1. Energy Savings: The water pump is an electrical device used to supply water to buildings and facilities. Frequent turning on and off of the pump increases its energy consumption. The automatic pump controls water pressure and flow precisely, preventing the pump from turning on and off repeatedly. This reduces energy consumption and saves on electricity costs.

  2. Extended Pump Lifespan: The water pump is a mechanical device subject to wear and tear. Excessive operation of the pump can cause damage. The automatic pump prevents the pump from overworking, thus protecting it from damage. This increases the pump’s useful lifespan.

  3. Maintaining Water Quality: Severe fluctuations in water pressure can damage faucets and other water supply equipment. The automatic pump prevents such pressure fluctuations, protecting faucets and other water-related equipment. This helps maintain water quality.

  4. Ease of Use: This type of water pump operates automatically, requiring no user intervention. This enhances the convenience of using the water pump.

Overall, the automatic pump is a practical device that offers numerous benefits for users.

How to choose the right automatic water pump.

Choosing the appropriate automatic water pump (single-phase submersible pump, three-phase submersible pump) depends on several factors, including:

  1. Type of Pump

    • Automatic Water Pump for Centrifugal Pumps: This device is suitable for centrifugal pumps used in irrigation, water purification, and other applications.
    • Automatic Water Pump for Diaphragm Pumps: This automatic water pump is suitable for diaphragm pumps used for transferring water, chemicals, and other liquids.
    • Automatic Water Pump for Gear Pumps: This automatic water pump is suitable for gear pumps used for transferring water, oil, and other lubricants.
  2. Required Flow Rate
    The required flow rate is the amount of water the pump needs to pump over a specified period. To determine the required flow rate, you should consult an engineer or irrigation expert.

  3. Type of Water Source
    The automatic water pump must be compatible with the type of water source. Some types of water sources include:

    • Groundwater Source: Water is supplied from a well or underground water source.
    • Surface Water Source: Water is supplied from rivers, lakes, or ponds.
  4. Environmental Conditions
    The automatic water pump should be able to operate under various environmental conditions, including temperature, humidity, and dust.

To choose the appropriate automatic water pump, you should consider all the factors mentioned above. Based on your needs and environmental conditions, you can select the best option.

Steps to install an automatic water pump.

First, you need to choose an appropriate location (for a domestic or industrial submersible pump) for installing the automatic water pump. This location should be easily accessible and not exposed to moisture or dust.

Next, you should connect the water pipes to this device. The water inlet pipe should be connected to the inlet of the automatic water pump, and the water outlet pipe should be connected to the outlet of the automatic water pump.

Finally, you need to connect the automatic water pump to the power supply.

The setup process for the automatic water pump is as follows:
First, you need to check the water pressure in the system. The water pressure should be at least 1 bar.

Then, you should configure the device. To adjust the automatic water pump, you need to turn two pressure adjustment screws for start pressure and stop pressure. The start pressure is the pressure at which the pump turns on, and the stop pressure is the pressure at which the pump turns off.

Finally, you should turn on the water pump.

When installing the automatic water pump, ensure that the water pipes are properly connected to it. Before starting the automatic water pump, check the water pressure in the system.

When adjusting the automatic water pump, make sure that the start and stop pressures are set correctly.

To adjust the automatic pump, turn the two adjustment screws for start and stop pressure. The start pressure is the pressure at which the pump turns on, and the stop pressure is the pressure at which the pump turns off. To adjust the start pressure, turn the start pressure adjustment screw clockwise (downward) to increase the start pressure. Turning this screw counterclockwise (upward) will decrease the start pressure.

To adjust the stop pressure, turn the stop pressure adjustment screw clockwise (downward) to increase the stop pressure. Turning this screw counterclockwise (upward) will decrease the stop pressure.

Before performing any work on the automatic water pump, you should disconnect its power supply.

When working with electricity, you must use appropriate safety equipment.
