Gear pumps in ships are positive displacement pumps used for transferring fuel, lubricating oil, and other viscous fluids. They operate by meshing gears to create suction and discharge flow, ensuring consistent pressure. These pumps are compact, reliable, and commonly used in marine applications for their efficiency and durability.

Size: Typically ranges from 1/2 inch to 12 inches in diameter.

Grade: Industrial-grade, marine-grade, and corrosion-resistant variants.

Viscosity: Suitable for fluids with viscosities ranging from 1 cP to 100,000 cP.

Buoyancy: Not applicable as gear pumps are not buoyant devices.

Material: Cast iron, stainless steel, bronze, or engineered plastics for corrosion resistance.

Flow Rate: 0.1 GPM to 500 GPM depending on size and design.

Pressure Range: Up to 3000 PSI for high-pressure models.

Temperature Range: -20°C to 200°C, depending on material and sealing.

Drive Type: Electric motor, hydraulic, or mechanical drive.

Sealing: Mechanical seals or lip seals for leak-proof operation.

Applications: Fuel transfer, lubrication, hydraulic systems, and cargo pumping.

Compliance: Meets ISO, ABS, DNV, and other marine standards.
