Marine Screw Pump

Overview

Marine screw pumps deliver pulsation-free, low-shear transfer of viscous/particle-laden media, excelling in fuel transfer, lubrication, and wastewater applications. Engineered for stable operation under vessel motion while complying with ISO standards.

Working Principle

Helical Engagement: Precision-meshing screws create sealed chambers for axial fluid progression

Pulsation Control: <±2% flow fluctuation vs gear pumps' ±10%

Shear Sensitivity: Ideal for emulsions and polymer additives

Applications

（1）Heavy Fuel Oil Transfer

      Media: 380cSt HFO, asphaltic residues

      Requirements: 5-200m³/h flow, ≤4.0MPa pressure

      Model: Triple-screw pumps

（2）Sludge Recovery

      Media: Oily sludge with ≤15mm solids

      Requirements: ≥8m self-priming

      Model: Single-screw pumps

（3）Lube Oil Circulation

     Media: ISO VG 460 cylinder oils, synthetic esters

     Requirements: ±1% metering accuracy, 180°C tolerance

     Model: Twin-screw pumps
