High-Volume Seawater Solutions with 30 Years of Field Expertise

Reliable Fluid Handling for the Maritime Industry

In the demanding environment of modern shipbuilding and marine engineering, the reliability of fluid systems is non-negotiable. Our horizontal double suction split case pumps are specifically engineered to handle high-capacity requirements while resisting the aggressive nature of seawater.

Leveraging 20 years of practical field experience in water supply systems and retrofitting, FILIPUSI provides pumps that balance hydraulic excellence with operational durability.

Engineered for marine-grade reliability, FILIPUSI horizontal double suction split case pumps deliver exceptional flow rates for seawater cooling, ballast water management, and on-board fire protection. The horizontal split design allows for rapid internal inspection without disturbing piping, ensuring minimum downtime during vessel operations.

Why Choose the Horizontal Split-Case Configuration?

Rapid Maintenance access

The horizontal split design allows the upper casing to be removed without disturbing the suction or discharge piping. This is critical for shipboard repairs where dry-dock time is limited.

Maximized Structural Stability

The horizontal orientation provides a lower center of gravity compared to vertical models, significantly reducing vibration during high-sea operations and increasing the lifespan of bearings.

Built for Harsh Seawater EnvironmentsSeawater circulation flow in corrosion resistant marine double suction centrifugal pump

Our marine pumps utilize optimized material selections to combat seawater corrosion:

  • Bronze Impellers: Resistant to erosion-corrosion in high-velocity flows.
  • Duplex Stainless Steel: Offers superior strength and resistance to pitting in chloride-rich environments.
  • Mechanical Seals: Specialized seawater-resistant seals to prevent leakage in continuous industrial operations.

Core Marine Applications

These pumps are engineered for critical shipboard infrastructure:
● Seawater Cooling Systems
● Shipboard Ballast Operations
● Marine Circulation Systems 
● On-board Fire Protection & Emergency 
● Vessel Water Management
