Why Choose Horizontal Split-Case Architecture?
|
Rapid Overhead Maintenance The axially split upper casing lifts easily to grant immediate inspection of bearings, seals, and impellers without unbolting pipeline connections, drastically cutting dry-dock downtime. |
Low-Vibration Base Mounting Horizontal mounting lowers the center of gravity compared to vertical pumps, minimizing operational vibration during heavy sea states and boosting bearing operational longevity. |
Double Suction Hydraulic Balance Liquid enters both sides of the impeller simultaneously, neutralizing axial hydraulic thrust and reducing seal stress for vibration-free continuous duty. |
Marine Metallurgical Armor Customized bronze alloys (C95800) and Duplex Stainless Steels prevent erosion-corrosion, pitting, and galvanic failure in high-velocity seawater loops. |

Marine Pump Engineering FAQ
Q: How does FILIPUSI guarantee long service life against aggressive seawater corrosion?
A: We utilize specialized Bronze alloys (C95800 Nickel-Aluminum Bronze) and Duplex Stainless Steel (2205/2507) specifically cast for raw seawater exposure to eliminate galvanic pitting and velocity erosion.
Q: Can these horizontal double suction pumps be integrated with smart VFD controllers?
A: Yes. All our units are fully VFD/PLC-compatible, allowing automated speed adjustments to lower power consumption during low-demand cooling cycles and meet EEXI/CII energy efficiency standards.
