Marine Gear Pump
Marine gear pump is a type of positive displacement pump commonly used in marine applications to transfer fluids such as fuel, oil, and water. It consists of two or more gears, typically meshed together, within a housing or casing. The gears rotate, creating chambers between their teeth, which trap and move the fluid from the pump’s inlet to its outlet.
Marine gear pumps are known for their ability to provide a steady flow of fluid at a constant pressure, making them suitable for various tasks on boats and ships. They are often used for transferring fuel from storage tanks to engines, circulating lubricating oil, transferring water for cooling systems, and other fluid transfer applications.
Marine gear pumps are available in different sizes and capacities to accommodate various flow rate requirements. They can be driven by an electric motor, a diesel engine, or other power sources commonly found on marine vessels.
Ship Gear Pump Types
There are several types of marine gear pumps commonly used in marine applications. External gear pump consist of two meshing external gears that efficiently transfer fluid. Internal gear pum feature an external gear and a larger internal gear that work together to smoothly transport fluids. Gerotor pumps utilize an outer rotor with internal gears and an inner rotor with external gears to provide high efficiency. Lobe pumps, with rotating lobes creating fluid chambers, are ideal for handling viscous or shear-sensitive fluids. Vertical gear pump offers a compact design with a vertical drive shaft, making them suitable for space-limited marine environments.

Marine Gear Oil Pump
KCB, 2CY, YCB Series Marine gear oil pump applies to deliver non-corrosive lubricating-oil or equivalent liquid without solid particles and fibers at temperature below 300℃ and with the viscosity of 5×10-6～1.5×10-3m2s (5-1500cSt). Reducing the speed, the pumps can delivery the liquid that the viscosity can be up to 5×104cSt.
Oil gear pump performance curve
Performance data of all gear pumps have been defined on basis of the viscosity of 4×10-5m2/s(40cSt). The data indicated in the performance diagram is suitable to medium viscosity of 1×10-5~ 8×10-5m2/s(10—80cSt). If which exceeds the above viscosity, the data will be re-defined according to the client’ s demands. The given exhausting pressure of all marine gear pumps is the highest working pressure, and pumps can perform normally within range of the rated working pressure, which can be found in Diagram NO.1.
YCB-G Model Heat Insulating Gear Pump
The heat insulating gear pump is a type of external gear pump. It features a tooth form that combines arcs and sine curves, allowing for efficient and steady transfer of various fluids with consistent output flow and pressure.
The pump casing is equipped with a heat insulating jacket and inlet and outlet joints, enabling the use of heat-conducting oil, steam, hot water, or cold water to heat, maintain warmth, or cool the transferred medium and the pump itself. It is important to note that when dealing with highly viscous fluids with a viscosity exceeding 1500cSt, it is recommended to reduce the pump speed to ensure optimal performance. This heat insulating gear pump is designed to provide reliable and controlled fluid transfer while accommodating different temperature requirements for the transferred medium.
