Centrifugal Pump · Pumps
Crew members and marine engineers depend on reliable pumping systems to maintain essential operations aboard ships. Naniwa Pump's DRV model, a vertical centrifugal pump designed for marine service, ensures smooth operation in both sea water and fresh water environments. Engineered with an electric drive, this pump is crucial for various shipboard functions, from ballast control to cargo handling. Common issues include line shaft bearing wear, mechanical seal leakage, impeller corrosion, and vibration due to shaft misalignment. Regular maintenance focusing on monitoring vibration, checking for leaks, and inspecting discharge pressure is essential. Spare parts such as seal kits, line shaft bearings, wear rings, shaft sleeves, and gaskets should be kept readily available for prompt repairs during overhauls.
