Overview
This HTS classification covers hydraulic pumps specifically designed for fluid power applications, which operate using gears to displace and move hydraulic fluid. These pumps are characterized by their internal mechanism, where meshing gears create chambers that expand and contract to draw in and expel fluid under pressure, generating the power for hydraulic systems. Examples include pumps used in heavy machinery, construction equipment, and industrial manufacturing processes where controlled hydraulic force is required.
The "Gear type" designation distinguishes this category from its sibling, 8413.60.00.20, which specifically enumerates vane type pumps. While both are rotary positive displacement pumps within the hydraulic fluid power category, the operative mechanism for fluid displacement is the key differentiator. Vane pumps utilize vanes that slide in and out of a rotor, whereas gear pumps rely on the meshing action of rotating gears.
As a leaf node, this classification does not have further subcategories. Therefore, classification within 8413.60.00.30 relies on confirming the pump's function as a hydraulic fluid power pump and its specific internal construction utilizing gears for positive displacement, differentiating it from other pump types or classifications.
