Principle of Operation

The Ebara centrifugal pumps follow the standard centrifugal principle. Two main parts are responsible for the conversion of energy: the impeller and the casing. The impeller rotates the fluid while the casing is the airtight passage that surrounds the impeller. To work, the fluid enters into the casing, falls on the impeller blades at the eye of the impeller, and is whirled tangentially and radially outward until it leaves the impeller into the diffuser part of the casing. The fluid gains both velocity and pressure while it passes through the impeller which is mechanized by the motor. This is how the pump can push out the fluid to a high-level head.
