A protective barrier positioned at the entry point of a water extraction system located within a body of fresh water. Its primary function is to prevent debris, aquatic life, and sediment from entering the pump, ensuring efficient and uninterrupted operation. A common application is in irrigation systems drawing water from a natural reservoir.
This preventative component is vital for maintaining the longevity and performance of the pumping mechanism. By filtering out particulate matter, it reduces the risk of clogging, impeller damage, and decreased flow rates. Historically, rudimentary versions were employed, but advancements in materials and design have led to more effective and durable solutions, contributing significantly to water resource management and efficient water usage.
