ABSTRAK Salah satu rotating machinery yang menunjang fasilitas produksi di PT. Pertamina EP Asset 4 Field Cepu adalah pompa sentrifugal single stages. Pompa sentrifugal paling banyak terpasang (ter-install) di lokasi PPP Menggung. Salah satu merk pompa tersebut adalah Deeb Blue, yaitu pompa sentrifugal Single Stages. Dalam pelaksanaan operasionalnya, banyak sekali kerusakan-kerusakan yang terjadi. Sehingga mengakibatkan rendahnya keandalan (reliability) dan ketersediaan (availability) pompa tersebut. Permasalahan teknik yang sering terjadi adalah kebocoran fluida dari mechanical seal pompa, temperatur bearing yang tinggi, impeller mengalami korosi, keausan wearing ring impeller hingga mengenai base metal cassing. Evaluasi ini dapat digunakan sebagai dasar untuk mengetahui penyebab kerusakan pompa dan mencari solusi yang terbaik untuk mencegah kerusakan pompa. Dengan mengetahui kinerja pompa maka dapat dihitung besarnya NPSHa (Net Positive Suction Head yang tersedia) dan NPSHr (Net Positive Suction Head yang diperlukan) agar dapat di evaluasi apakah terjadi kavitasi, karena dengan adanya kavitasi menyebabkan rusaknya pompa. Metode evaluasi ini dengan cara pengambilan data, perhitungan dan evaluasi. Pada perhitungan daya pompa sebesar 2,5399 kW dan daya poros sebesar 2,988 kW. Sedangkan dari perhitungan NPSH nilai NPSHa sebesar 1,885 m sedangkan NPSHr sebesar 3,2 m sehingga kerusakan pompa disebabkan kavitasi. Maka solusi untuk menghidari kavitasi dengan cara mesndesain ulang sistem perpipaan di bagian suction dan dilakukan perhitungan kembali. Dari hasil perhitungan di dapatkan nilai NPSHa sebesar 3,789 jadi pompa Deep Blue sudah tidak mengalami kavitasi. Kata Kunci : Pompa Sentrifugal, Kerusakan, Evaluasi, Solusi ABSTRACT One of the rotating machinery to support the production facility at PT. Pertamina EP Cepu Field Asset 4 is a single centrifugal pump stages. The most widely installed centrifugal pump (installed) in the PPP Menggung location. One brands such pumps are Deeb Blue, which is a centrifugal pump Single Stages. In the implementation of its operations, a lot of the damage that occurred. Thus resulting in poor reliability (reliability) and availability (availability) of the pump. Technical problems that often happens is the leakage of fluid from the pump mechanical seal, bearing high temperature, corrosion impeller, wear impeller wear ring to the base metal casing. This evaluation can be used as a basis to determine the cause of damage to the pump and find the best solution to prevent pump damage. By knowing the performance of pumps are used to determine the amount of NPSHa (Net Positive Suction Head available) and NPSHR (Net Positive Suction Head required) to be evaluated whether cavitation occurs, because of the presence of cavitation caused damage to the pump. This evaluation method by means of data collection, calculation and evaluation. In the calculation of 2.5399 kW of pump power and shaft power of 2.988 kW. While the calculation of NPSH value NPSHa of 1,885 m by 3.2 m, while NPSHR that pump damage caused by cavitation. So the solution to avoid cavitation by means mesndesain the piping system at the suction and do perhtungan back. From the calculation results get NPSHa value amounted to 3,789 so the pump Deep Blue had not experienced cavitation. Keywords : Centrifugal Pumps, Damages, Evaluation, Solutio
