Understanding the Pump Pressure Switch

A pump pressure switch is a device that monitors the water pressure in a water supply system. It is typically installed near the water tank or well and connected to the pump's electrical circuit. The pressure switch works by sensing the pressure in the water supply system and turning the pump on and off accordingly.

When the pressure drops below a certain level, the switch sends a signal to the pump to turn on and start pumping water into the system. When the pressure reaches a certain level, the switch sends a signal to the pump to turn off.

There are different types of pump pressure switches available in the market. The most common types are the diaphragm type and the bellows type. The diaphragm type is more commonly used and is known for its durability and reliability.

The bellows type, on the other hand, is more sensitive to pressure changes and is often used in low-pressure applications.

In conclusion, a pump pressure switch is an essential component of water supply systems. It helps to ensure that the water pressure in the system remains within the desired range, thereby preventing damage to pumps and other components of the system. Understanding the function of the pressure switch and the different types available is crucial for proper maintenance and adjustment of the system.
