Marine Twin Screw Pump

Marine Twin Screw Pump – High-Efficiency Double Screw Pump for Marine Applications

Product Overview
The Marine Twin Screw Pump, also known as a Marine Double Screw Pump, is a highly efficient positive displacement pump specifically engineered for demanding marine and industrial applications. Featuring an advanced double-suction design, this pump automatically balances axial forces by maintaining both screw ends within the same pressure chamber. Its externally mounted bearings are independently lubricated, ensuring reliable performance completely isolated from pumped media. Equipped with precision synchronous gears that maintain minimal clearance between non-contacting screws, this pump minimizes wear and handles impurities without direct abrasive contact. Most models include an integrated safety valve for overpressure protection (standard on pumps above 2.0 m³/h capacity).

Key Features & Benefits

Axial Force Balance: Double-suction structure eliminates axial thrust for reduced bearing load
External Bearing System: Independently lubricated bearings prevent media contamination
Non-Contact Operation: Synchronous gear drive maintains precise screw clearance without metal-to-metal contact
Overpressure Protection: Built-in safety valve protects system components (standard on most models)
Flexible Port Configuration: Horizontal inlet/outlet or horizontal inlet/vertical upward discharge options
Abrasion Resistance: Handles impurities without direct screw surface contact (minimal冲刷 wear)
High-Viscosity Capability: Efficiently handles fluids from 1 to 3,000 mm²/s (up to 1,000,000 mm²/s at reduced speeds)
