Abstract
Pompa sentrifugal sering dijumpai hampir di seluruh sektor kehidupan, seperti sektor energi, maritim dan lain-lain. Pada pengaplikasianya, pompa sentrifugal sering menjumpai masalah-masalah tertentu. Pompa yang digunakan seringkali melebihi dari kebutuhan yang ada. Akibatnya timbul kerugian pada sisi performansi pompa dan biaya dalam pengoperasiannya. Trimming impeller merupakan cara yang paling diminati dalam meningkatkan performansi suatu pompa. Pada penelitian ini mengevaluasi pengaruh trimming impeller dengan variasi putaran motor terhadap performansi pompa. Diameter impeller dipotong pada rentang 10%-20% dari diameter asli, dimana diameter asli dari impeller sebesar 126 mm. Pompa yang digunakan memiliki kapasitas maksimum sebesar 92 L/menit dan head total sebesar 22 m. Pompa terinstalasi pada CUSSON friction in pipeline apparatus yang digerakkan oleh motor listrik dengan daya 370 Watt. Pengukuran dilakukan dengan menggunakan pressure gauge untuk mengukur tekanan pada sisi isap dan buangan. Clamp meter untuk mengukur tegangan dan arus pada pompa. Parameter yang dievaluasi pada penelitian ini meliputi head pompa, daya pompa, dan efisiensi pompa. Hasil dari penelitian ini menunjukkan bahwa seluruh data yang diperoleh sesuai dengan hukum afinitas. Parameter yang dievaluasi yaitu head pompa, daya pompa, dan efisiensi pompa menunjukkan penurunan seiring menurunnya diameter impeller dan kecepatan putaran motor. Pada trimming impeller pada rentang 10%-20% dari diameter awal tidak menunjukkan adanya kenaikan efisiensi pompa. Efisiensi terbaik setelah pemotongan diperoleh pada diameter 111 mm sebesar 34,85% pada kecepatan putaran 2850 rpm dan 11,27% pada kecepatan putaran 1500 rpm.

Centrifugal pumps are used in practically every aspect of life, including the energy and marine industries. Pumps are frequently utilized more than what is required. As a result, reductions in pump performance and operational expenses occur. The most common method for increasing a pump's performance is impeller trimming. In this study evaluated the effect of impeller trimming with variations in motor rotation on pump performance. The impeller diameter is reduced by 10%-20% of its original diameter, with the original diameter of the impeller is 126 mm. The pump has maximum capacity is 92 L/minute and total head is 22 m. The pump is set up on the CUSSON friction in pipeline apparatus, which is powered by a 370-watt electric motor. Pressure gauge is used to measure the pressure on the suction and discharge sides. Clamp meter is used to measure the voltage and current at the pump. Parameters evaluated in this study include pump head, pump power, and pump efficiency. The results of this study indicate that all data obtained are in good agreement with the law of affinity. Pump head, pump power, and pump efficiency decrease as the decreasing impeller diameter and motor rotation speed. Trimming the impeller to 10%-20% of its original diameter has no impact on pump efficiency. At a diameter of 111 mm, the best efficiency after cutting was 34.85% at a rotational speed of 2850 rpm and 11.27% at a rotating speed of 1500 rpm.
