What is the difference between centrifugal pump and jet pump?

Centrifugal pumps and jet pumps are both used to move fluids, but they operate differently and are suited for different applications.

Centrifugal pumps use a spinning impeller to create a centrifugal force that moves the fluid through the pump and into the discharge pipe. The fluid enters the pump through an inlet and is directed to the impeller, which spins at a high speed to push the fluid out through the discharge port. Centrifugal pumps are efficient and reliable, and they can handle a wide range of flow rates and pressures. They are commonly used in applications such as water supply systems, irrigation systems, and industrial processes.

Jet pumps, on the other hand, use a jet of fluid to create a pressure difference that moves the fluid through the pump. A jet pump has two sections: a shallow well injector and a deep well ejector. The injector section draws water from the well and mixes it with a high-pressure stream of water, creating a high-velocity jet that drives the water through the ejector and up to the surface. Jet pumps are typically used in applications such as wells, underground storage tanks, and booster systems. They are often used in rural areas where municipal water supplies are not available.

In summary, centrifugal pumps use a spinning impeller to move fluid through the pump, while jet pumps use a jet of fluid to create a pressure difference that moves the fluid. Centrifugal pumps are more efficient and reliable, and are suited for a wider range of applications, while jet pumps are commonly used in rural areas for well and booster systems.
