WebA plant has installed a single-suction centrifugal pump with a discharge of 68 m3/hr under 60 m head and running at 1 200 rpm. It is proposed to install another pump with double suction but of the same type to operate at 30 m head and deliver 90 m3/hr. WebOct 9, 2011 · A centrifugal Pump impeller has an external diameter of 12 inches and a discharge area of 1.2ft. The blades are bent backwards so that the direction of the relative velocity at the discharge surface makes an angle of 145 degrees with the tangent to this surface drawn in the direction of the impeller rotation.
