Engineered Advantages & Centrifugal Superiority
|
Back-Pull-Out Maintenance Allows ship mechanics to service or replace rotating elements (shaft, impeller, mechanical seal) without unbolting suction or discharge piping. |
Heavy-Duty Rigid Baseplate Structural horizontal mounting frame absorbs axial thrust and shipboard vibration, ensuring shaft alignment under severe sea states. |
Marine Metallurgical Armor Impellers, wear rings, and casings cast in Nickel-Aluminum Bronze (C95800) or Duplex SS to eliminate galvanic corrosion in raw seawater. |
CFD Balanced Low-Vibration Precision CFD hydraulic design prevents localized cavitation, lowering noise levels and dramatically extending bearing and seal operational lifespans. |

Structural Rigidity & Back-Pull-Out Design: Features a heavy-duty fabricated steel baseplate to absorb axial thrust and hull vibrations, paired with a back-pull-out end-suction casing that allows quick impeller servicing without dismantling suction or discharge piping.
Primary Maritime Systems & Applications
FILIPUSI’s marine horizontal centrifugal pump series serves as the primary fluid circulation workhorse across diverse vessel engineering nodes. Built for continuous 24/7 duty, these units deliver robust performance across critical shipboard systems:
| • | Main & Auxiliary Engine Cooling Loops: Delivers steady, high-volume raw seawater or freshwater circulation through central heat exchangers, maintaining optimal engine operating temperatures. |
| • | Shipboard HVAC & Chilled Water Circulation: Provides constant, pulse-free chilled water circulation throughout closed-loop vessel climate control networks. |
| • | Ballast Water Transfer & Bilge Utilities: Engineered for multi-tank trim balancing, general washdown, and rapid bilge water discharge during emergency sea operations. |
| • | Auxiliary Boiler Feed & Fire-Fighting Services: High-head configurations configured for high-pressure deck washdown, auxiliary boiler feed, and standby fire-fighting circuits. |
Frequently Asked Questions (FAQ) — Marine Horizontal Pumps
Q: What is the benefit of a Back-Pull-Out horizontal marine pump during vessel maintenance?
A: The Back-Pull-Out feature enables marine engineers to remove the complete rotating assembly (bearing housing, shaft, mechanical seal, and impeller) without disconnecting the pump casing from suction and discharge piping, saving critical repair hours in dry-dock.
Q: Can FILIPUSI horizontal pumps be supplied with IACS marine class type approval?
A: Yes. We provide class certification and inspection reports from major international classification societies including ABS, BV, CCS, DNV, LR, NK, and KR according to client shipbuilding requirements.
