Abstract

Centrifugal pumps are the most commonly utilized in industries, agriculture, and households. In the microbubble generator, the centrifugal pump is driven by a DC motor for efficiency. This research was conducted to determine the optimal centrifugal pump design for microbubble generators using 3D-printed PLA material. The pump drive uses a brushless DC motor. With impeller dimensions r1=16mm, r2=26mm, β1=46.8, β2=62.8, and number of blades = 8, the resulting head is 2m at a constant operational current of 3A and a flowrate of 0 L/m. The same operational current input yields a maximum flow rate of 14 L/min with a head of 0.5 m. Maximum head exists when there is no liquid on the outlet side. At current ≥ 6.5A, there is a deviation from the previously formed trend. The input power of 58W is generated when the maximum flow rate is 25L/m. Maximum efficiency can be achieved as the input current increases to ≤6.5A and 18L/m. At conditions ≥6.5A, efficiency decreases drastically as the input current increases. This centrifugal pump design can work optimally at a constant input current of 6.5A with an input power 58W for the microbubble generator.
