Marine Gear Pump

Overview

Marine gear pumps deliver high-pressure, low-flow fluid transfer with compact design and robust performance, ideal for hydraulic systems, fuel pressurization, and lubricant circulation. Precision-engineered for 10-10000cP viscosity fluids under ISO cleanliness standards and DNV-GL certification.

Working Principle

Meshing Volume Variation:Driving/driven gears rotate to create sealed chambers.

Intake Phase: Chamber expansion creates vacuum suction.

Discharge Phase: Chamber compression forces fluid to outlet.

Flow Characteristics: Linear RPM-flow relationship, ±8-12% pulsation (external gear type).

Applications

(1)Deck Machinery Hydraulics

    Media: ISO VG 46/68 hydraulic oil

    Requirements: ≤25MPa, 5-200L/min

    Model: External gear pumps

(2)Fuel Boost Transfer

    Media: MDO/MGO/diesel

    Requirements: ATEX compliance, ≥5m self-priming
