Marine Hydrophore Unit

ZYG(S) Series Marine Hydrophore Unit – Marine Pressure Tanks for Fresh & Sea Water Systems

Product Overview
The ZYG(S) Series Marine Hydrophore Unit is essential marine pressure vessels designed for reliable water supply systems onboard ships and offshore installations. These robust hydrophore tanks serve as critical components in freshwater supply systems, seawater washing systems, and general marine water distribution networks. Manufactured with corrosion-resistant materials and CCS-B certified construction, these units ensure consistent water pressure for all onboard personnel and operational requirements.

Key Applications & Uses
• Marine Fresh Water Supply Systems – Potable water distribution for crew and passengers
• Shipboard Washing Water Systems – Seawater supply for cleaning and sanitation purposes
• Marine Plumbing Infrastructure – Integrated water pressure maintenance systems
• Vessel Hotel Services – Accommodation and galley water supply solutions
• Marine Engineering Systems – Auxiliary water supply for engine room operations

Operating Principle
The ZYG(S) Marine Hydrophore System maintains constant water pressure through compressed air technology. The vortex pump delivers water into the pressurized tank, where compressed air maintains system pressure between 0.3-0.4 MPa. The automatic pressure controller regulates pump operation, while safety systems ensure reliable performance:

Liquid Level Gauge: Provides visual indication of water levels
Pressure Gauge: Monitors system pressure in real-time
Automatic Pressure Control: Activates pump at 0.3 MPa, stops at 0.4 MPa
Safety Valve Protection: Releases pressure exceeding 0.42 MPa
Dual Control Modes: Manual and automatic operation options
