On the Tank Mounted Centrifugal Lubricating Oil Pump

Abstract

In accordance with recent development of large oil tanker, the output of marine diesel engine has become larger, and also large quantity of lubricating oil has been required for such large diesel engine. Accordingly the screw pump which has been usually used for the lubricating oil pump is not able to circulate so much capacity of oil that is required by large diesel engine with one pump. Therefore three (3) sets of the screw pump should be installed for one vessel including one (1) stand-by pump. We recently made our subcontractor design and manufactured the tank mounted centrifugal lubricating oil pump of large capacity. This centrifugal pump is able to circulate every necessary capacity for large diesel engine, so it is sufficient to install two (2) pumps for one vessel including one (1) stand-by pump. And also this pump is superior at characteristics in lubricating oil service. This article states some merits due to the application of the tank mounted centrifugal lubricating oil pump of large capacity, in comparison with the screw pump.
