The materials were cast iron, cast brass and cast iron coated with chemical polymer composite. Reducing surface roughness caused an increase in pump efficiency and a decrease in power requirement. The power requirement of the pump coated with polymer composite was 9.11 % less than that of the cast iron pump. Power requirement of the cast brass impeller was higher (1 %) than the cast iron pump for the open type pumps. Total head, pump efficiency and the flow rate of the cast brass impeller were higher than those of the cast iron impeller.eninfo:eu-repo/semantics/closedAccessCast Iron; Energy Efficiency; Energy Utilization; Impellers; Polymers; Surface Roughness; Cast Brass; Cast Iron Impeller; Flow Rate; Polymer Composites; Pump Efficiency; Centrifugal PumpsArticle37262672-s2.0-33747605295N/A
