What type of pump is typically used for oil pumping?

The type of pump that is typically used for oil pumping is a gear pump. Gear pumps are positive displacement pumps that use interlocking gears to move fluid through the system. Their design is particularly suited for handling viscous fluids like oil, as they can maintain a constant flow rate regardless of the pressure. The mechanical action of the gears ensures that oil is effectively drawn into the pump and expelled at high pressure.

This type of pump excels in applications requiring high-pressure delivery, making it ideal for transferring oil in various systems, including lubrication and hydraulic applications. The robust design of gear pumps and their efficiency in moving thick liquids contribute to their widespread use in oil and fuel transfer.
