Overview

The marine cooling water pump is a critical component of a vessel’s power system, providing circulating cooling water for engines, generators, and auxiliary equipment to ensure optimal operating temperatures. Compliant with energy efficiency and environmental standards, it is suitable for bulk carriers, container ships, LNG carriers, and more, balancing reliability and energy savings.

Drive Options

Electric Drive: Powered by the ship’s main or emergency generator, offering stable and low-noise operation for routine cooling cycles.

Variable Frequency Drive (VFD) : Adjusts pump speed to match cooling load variations, saving up to 30% energy and reducing carbon emissions.

Applications

Engine Cooling: Supplies stable cooling water to main and auxiliary engines, preventing overheating.

Central Cooling System: Integrates with plate heat exchangers for closed seawater-freshwater loops, minimizing corrosion risks.

Seawater/Freshwater Circulation: Adapts to diverse water sources (seawater, freshwater, or mixed media) for complex operational needs.

Performance Parameters

Flow Range: 50 ~ 2000 m³/h.

Head Range: 20 ~ 80 m .
