Marine gear pump is very suitable to handle the oil liquid. So the gear marine oil pump is very widely used in marine and offshore industry. The marine gear oil pump is used for oil supply, oil transfer and oil circulation and so on.
There are two main types of oil for marine purpose. One is for the fuel oil, for example the MDO, marine diesel oil and HFO, heavy fuel oil and so on. (It is called HFO gear pump, MDO gear pump, MGO gear pump). Another is the Lub oil. It is also named as lube oil, lubricating oil, lubrication oil or lubricant. (lube oil gear pump, lubricating oil gear pump). The marine gear oil pump is very suitable for the both type of oil. The marine gear pump sometimes can be used for sludge oil or waste oil. But the marine gear pump could be used for bilge or oily water.
There are two main gear types. The external gear pumps use two external spur gears. And the internal gear pumps use external and internal spur gears. SILI PUMP can offer both type of the marine gear pump. Usually, with simple construction, the external gear pump is more popular. However the internal marine gear pump is more suitable for the liquid with high viscosity.
Gear pumps are positive displacement pump, so does the marine gear pump. This mean the marine gear pump provide a constant amount of fluid for each revolution. Some gear pumps are designed to function as either a motor or a pump.
Compared with screw pump, gear pump production cost is much smaller. So it is really a good choice for the oil liquid. However, for some big capacity and high pressure, it will be out of the range of gear marine pump.
