Marine Centrifugal Pump

Overview

Engineered for harsh marine environments, marine centrifugal pumps deliver high-efficiency fluid transfer through centrifugal force, serving as critical components in ship cooling, ballast, and firefighting systems. Designed for seawater, freshwater, and low-viscosity oils with corrosion-resistant and low-maintenance features.

Installation Types

（1）Vertical

     1、Structural Features:

         Top-mounted motor with horizontal inlet/outlet,40% footprint reduction vs horizontal models

  2、Applications:

      ①Engine cooling systems: Space-constrained engine rooms

      ②Bilge water evacuation: Bottom suction in low-deck compartments 

  3、Advantages:

        ①Ideal for compact machinery spaces

        ②Enhanced dry-run tolerance (≥5 minutes for select models)

（2）Horizontal 

     1、Structural Features:

 Horizontal shaft with quick-access maintenance cover,In-line or right-angle port configurations

     2、Applications:

        ①Deck firefighting systems: Simplified piping layout

        ②Central cooling systems: High-flow stability with easy maintenance

    3、Advantages:

        ①30% extended bearing life from balanced loading

        ②Maintenance without pipeline disassembly
