Wilo 4249557 Centrifugal Pump
Product Description :
- It is a type of pump that uses rotational energy to move fluids. The core component of a centrifugal pump is the impeller, which is a rotating disk with blades. When the impeller spins, it imparts kinetic energy to the fluid, accelerating it outward from the center of the pump.
- After the fluid exits the impeller, it enters a volute or diffuser. This component converts the kinetic energy of the fluid into pressure energy, helping to move the fluid through the discharge pipe.
-
A Centrifugal Pump is a mechanical device designed to move liquids through the conversion of rotational kinetic energy to hydrodynamic energy. This energy is typically generated by an electric motor or engine-driven impeller that increases the velocity of the fluid, which is then converted into pressure in the pump casing.
-
Widely used for water supply, chemical transfer, HVAC systems, and industrial processing, centrifugal pumps are known for their simple design, efficient performance, and ability to handle large flow rates with consistent pressure.
