Marine Ejector Pump

Overview

Marine Ejector leverage motionless fluid dynamics for suction, mixing, and pressure boosting, delivering maintenance-free operation in hazardous/emergency scenarios. Compliant with SOLAS and ISO, these pumps excel in ballast systems, cargo holds, and explosive environments.

Working Principle

Venturi Effect:High-velocity motive fluid (water/steam/air) creates low-pressure zone to entrain secondary fluid.

Energy Conversion:Mixed flow decelerates in diffuser, converting kinetic energy to static pressure.

Self-Priming: 8-10m lift capability (motive pressure dependent).

Applications

(1)Emergency Bilge Dewatering

    Motive Fluid: Firemain seawater (0.7-1.2MPa)

    Capacity: 20-200m³/h with ≤15mm solids

    Advantage: Power-independent operation

(2)Cargo Tank Gas Evacuation

   Motive Fluid: Compressed air (0.5-0.8MPa)

   Performance: 90% vacuum (IGC Code compliant)

   Certification: ATEX Zone 1 approved

(3)Ballast Water Mixing

   Motive Fluid: High-pressure seawater

   Purpose: Sediment prevention

(4)Vacuum Sanitation Systems

   Motive Fluid: Fresh/seawater (0.3-0.6MPa)

   Capacity: ≤25mm waste handling

   Standard: USPH/MLC 2006 compliant

Certification

DNV/ABS/LR/CCS/BV.Etc.
