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.
