Hydraulic pump profiles are aluminium alloy profiles manufactured through an extrusion molding process. They are not the final product, but rather semi-finished blanks used by hydraulic pump manufacturers to process into hydraulic pump housings. These profiles feature precisely pre-formed internal cavities and external walls, greatly simplifying the manufacturing process of hydraulic pump housings and improving production efficiency and material utilization. Therefore, hydraulic pump profiles are a key foundational material for the modern hydraulic industry's move towards efficient, precise, and lightweight manufacturing.
1. Product Advantages
It features high precision and complexity, good toughness, fatigue resistance, and machinability. The aluminium alloy's good thermal conductivity helps dissipate heat during hydraulic pump operation, maintaining system stability. The extruded inner surface is smooth and dense, free from casting defects such as sand holes and porosity. This not only reduces machining allowances but also lowers fluid flow resistance, improving the volumetric efficiency and service life of the hydraulic pump. It offers high production efficiency and economic benefits, being almost a "net-shape" process with a scrap rate far lower than solid bar milling. The material source is clear, with uniform properties, facilitating quality control and traceability.
2. Technical Parameters
| Tensile strength | ≥ 350 MPa (up to 387 MPa after optimized aging treatment) |
| Yield strength | ≥ 290 MPa (up to 345 MPa after optimized aging treatment) |
| Elongation after fracture | ≤ 16.0% (typical value approximately 15.5%) |
3. Product Uses
Commonly used alloys are 6061/6082/7075. Hydraulic pump profiles are mainly used to manufacture housings for core components of various hydraulic systems: Piston pump/motor housings: Axial piston pumps and swashplate piston pumps are the primary applications. Gear pump housings: Used for internal and external gear pumps. Vane pump housings. Hydraulic valve blocks/manifolds: Serving as mounting bases for hydraulic valves, they contain complex internal cross-flow circuits. Other hydraulic component housings: Such as hydraulic motors, hydraulic steering gears, etc.
