Why is the booster pump constantly making noise?

[StHarper]

There are mainly two reasons why a pressure pump keeps making noise: damage to the pressure switch and failure of the check valve. If the pressure switch is damaged, it cannot sense the normal pressure conditions, causing the pump to keep working and making noise continuously. If the check valve fails, it cannot prevent water from flowing back into the pump, which prevents the water pressure from reaching the set level, resulting in continuous operation and noise. Below are the types of booster pumps: 1. Biogas booster pump: This is a pneumatic design, available in gas-liquid and gas types. It operates based on the principle of low air pressure and high hydraulic pressure during piston movement. If the air source pressure is insufficient, a booster pump can be used to increase the pressure. 2. Gas-liquid booster pump: This type is generally used for gases or liquids, such as when water pipe pressure is insufficient. These products are mainly made of aluminum alloy, and the parts in contact with liquids are made of carbon steel or stainless steel, depending on the liquid type. 3. Air booster pump: Similar to the first type, this pump operates using the effect generated by piston movement. It can be used in original air compression systems, increasing air pressure by about 5 times during operation.
