Penyebab kerusakan diatas, pompa mengalami penurunan performa sehingga perlu adanya reparasi agar tidak mengalami suatu dampak yang lebih serius. Dengan dilakukan penggantian seal, bearing dan memperbaiki poros. Pompa setelah direparasi kami analisa hasil menguji performa pompa dengan menghitung head pump, daya pompa dan daya motor setelah direparasi. Pompa dioperasikan selama kurang lebih tiga tahun, pompa mengalami kerusakan pada bearing, seal dan poros hal ini mengakibatkan penurunan performa. Tercatat performa awal pompa equipment 713WP ini memiliki debit 250 m 3 /jam menjadi 170m 3 /jam, untuk itu kami melakukan perbaikan.
