Gear pump is used for oil extraction. Gear pump: The gear pump generates power through gear rotation. The meshing process of gears has a higher possibility of wear, resulting in a shorter lifespan for the gears. Therefore, the gears in the pump often need replacement. Moreover, replacing a gear pump is costly, making it a high-cost component replacement. Diaphragm pump: The diaphragm pump generates power through the back-and-forth friction of the pump diaphragm. The contact area of the diaphragm is smaller, resulting in less wear and a longer lifespan compared to the gear pump. Replacing a worn diaphragm is relatively inexpensive. In usage, gear pumps consume more oil, while diaphragm pumps are more economical in terms of consumables.
