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.
