ASN
Horizontal Split Casing Centrifugal Sea Water Destination PumP
ASN Series Horizontal Split Casing Centrifugal Pump adalah pompa sentrifugal single-stage, double suction, horizontal split casing (axially split) yang dirancang khusus untuk aplikasi transfer air laut (sea water), air industri, dan sistem pendingin.
Pompa ini memiliki desain casing terbelah secara horizontal sehingga memudahkan maintenance tanpa harus melepas pipa utama. Impeller double suction memberikan keseimbangan hidrolik yang sangat baik sehingga mengurangi axial thrust dan meningkatkan efisiensi.
