Buyers must verify that the pump they are purchasing strictly adheres to the standard indicated by the model number, as deviations can lead to incompatibility with the grader's hydraulic system.

The Standard attribute also appears with values like Standard and specific weight or load indicators such as 0.5kg or 10kg. While these may seem like simple descriptors, they often refer to the product's adherence to a specific industry norm or its rated capacity. The presence of a Standard value of 143.11KG in the data suggests that some heavy-duty units have specific weight classifications that must be accounted for in logistics and installation planning.

Cost Drivers and Pricing Dynamics

The pricing structure for grader parts hydraulic pumps is influenced by a multitude of factors, resulting in a wide observed range of 1 to 50,000 USD. This vast disparity is not arbitrary but reflects the fundamental differences in the components being sold. The lower end of the spectrum likely corresponds to smaller auxiliary components, such as Hydraulic fittings, Hydraulic valves, or minor Spare Parts like seals and gaskets. These items, while essential, have lower manufacturing costs and material requirements compared to full pump assemblies.

Conversely, the higher price points are associated with complete hydraulic pump units, particularly those from the K3V series or other complex piston pump models. The cost of these units is driven by the precision engineering required for the Pistons and Cylinder assemblies, the quality of the Steel used, and the complexity of the Hydraulic power system integration. The Customization attribute being Available also plays a significant role in pricing. Buyers requesting Customized Size or specific modifications to the prod_packing or internal specifications will incur additional costs compared to purchasing off-the-shelf standard models.

The prod_packing method is another cost driver. Options range from Carton Box and Carton to Wooden Box and Export Standard Package. While a Carton is suitable for smaller, lighter components, larger pumps often require Wooden Box packaging to prevent damage during transit. The Ocean Freight option mentioned in the data indicates that shipping costs are a significant variable, especially for heavy units. Buyers must factor in the logistics of transporting these items from China or Shandong China to their destination, as freight charges can substantially impact the total landed cost.
