Frequently Asked Questions
Q1: What materials are best for seawater pumps?
A1: For raw seawater service, Ni-Al Bronze (nickel-aluminum bronze) is the industry standard due to its excellent resistance to chloride pitting, cavitation, and marine fouling. For more corrosive applications (e.g., ballast water treatment, SWRO feed), Duplex Stainless Steel 2205 or Super Duplex 2507 is recommended for higher strength and corrosion resistance. AISI 316L is suitable for mild seawater or brackish water service.
Q2: What marine classification society certifications do you offer?
A2: FILIPUSI marine pumps can be supplied with documentation and certification from all major classification societies, including CCS (China Classification Society), ABS (American Bureau of Shipping), DNV (Det Norske Veritas), BV (Bureau Veritas), LR (Lloyd's Register), and NK (Nippon Kaiji Kyokai). We provide full type approval documentation, material test reports (MTR), hydrostatic test reports, and third-party inspection certificates as required by the classification society and vessel flag state.
Q3: Can you provide custom dimensions for vessel retrofitting?
A3: Yes. FILIPUSI specializes in custom-engineered marine pumps for vessel retrofitting and fleet modernization. We can manufacture pumps with custom flange-to-flange dimensions, shaft heights, and baseplate mounting patterns to match existing engine room boundaries and legacy flanges, enabling drop-in replacement of aging equipment without pipe modification. Send us your existing pump dimensions or GA drawing, and our engineers will provide a custom proposal within 24 hours.
