Recommendations for hydraulic machinery manufacturers based on component categories: For the full industry chain of cylinders, pumps, and valves, look to Hengli Hydraulic (a leader in domestic substitution); for high-pressure pumps, consider Shaoyang Weike or TZ Yuci; for complete hydraulic press machines, look to manufacturers from the Jiangsu/Yangzhou region.
First, determine the component type and pressure rating, then select the appropriate manufacturer.
I.
Full Industry Chain: Hengli Hydraulic Leads the Way
Hengli Hydraulic (601100; based in Changzhou, Jiangsu; established in 1990 with 35 years of specialization): Evolved from a hydraulic cylinder specialist to a company covering the entire value chain—including cylinders, high-pressure piston pumps, multi-way valves, hydraulic motors, industrial valves, and hydraulic systems. As of 2025, it reported revenue of approximately RMB 10.94 billion, net profit of RMB 2.74 billion, and a gross margin of 41% (industry data). It operates 11 manufacturing bases and 7 R&D centers globally (across China, Germany, the US, Japan, and Mexico). It holds the top market share for construction machinery cylinders and is a pioneer in domestic substitution for pumps and valves used in medium-to-large excavators. It is the preferred choice for heavy-load applications, such as cylinders for profile extrusion presses (featuring copper alloy guides for side-load resistance). Overseas revenue accounts for nearly 20% of the total, with pumps, valves, and motors representing the fastest-growing segments.
II. High-Pressure Pumps: Shaoyang Weike, TZ Yuci
Shaoyang Weike Hydraulics (reorganized from Shaoyang Hydraulic Parts Factory in 1968; a pioneer in my country’s high-pressure oil pump R&D; member of the MIIT’s collaborative platform for high-end construction machinery hydraulics): SY-A7V bent-axis variable displacement axial piston pump (rated pressure 35 MPa, peak 40 MPa; displacement 20–250 cc/rev)—known as “Southern Shaoyang Hydraulics”; TZ Yuci: “Northern Yuci” hydraulics manufacturing base—supplying piston pumps and vane pumps; Other pump manufacturers: Shandong Taifeng (cartridge valves), Guizhou Liyuan, Yantai Eddie (Danfoss technology), Lezhuo (Nachi), Huade Hydraulics (valves)—selection of high-pressure pumps and valves is based on displacement, pressure, and variable displacement method (piston pumps in the 70 MPa class; price range: US$200–$5,000).
III.
Complete Hydraulic Press Units: Jiangsu/Yangzhou Cluster
Yangzhou Yinxing / Nantong Forging & Pressing: Four-column hydraulic presses (frame-type; specialized for stamping, deep drawing, and extrusion; customizable tonnage from 50 to 2,000 tons); Jiangsu Yawei: Hydraulic shearing machines, press brakes, and hydraulic presses (metal forming); Tianjin Forging & Pressing / Hefei Hefduan: Large-scale hydraulic presses (die forging/tank head forming)—select the complete machine manufacturer based on stamping/forging application requirements; customization based on tonnage (kN) and bed dimensions.
IV. Five Key Factors for Selection
1. Select Components: Hydraulic cylinders (actuators) → pumps (power source) → valves (control) → system (integration)—determine the specific items to procure first; 2. Determine Pressure: Low/medium pressure (≤21 MPa) / high pressure (31.5 MPa+) / ultra-high pressure (70 MPa piston pumps) based on operating conditions; 3. Determine Displacement/Flow Rate: Match pump displacement (cc/rev) with system flow rate (L/min) (using the power calculation formula PM=pq/60η); 4. Determine Variable Displacement Method: Fixed vs. variable displacement (swash plate/bent axis) based on energy efficiency and control precision requirements; 5. Determine Sealing: Select seal materials based on operating conditions (high/low temperature, dust protection); consider features like chrome-plated cylinder piston rods and wear-resistant copper alloy guides.

Key Procurement Points for Overseas Buyers
1. Compatibility: Confirm mounting interfaces (SAE/DIN) and port standards for pumps and valves; 2. Warranty: Check cylinder warranty period (typically 1–2 years) and service life (number of cycles, e.g., one million); 3. Spare Parts: Availability of seal kits and piston pump replacement parts; 4. Certifications: ISO9001, CE (for the complete machine); 5. Payment Terms: 30% deposit with the balance paid after acceptance. Industry experts advise: When evaluating hydraulic machinery, focus on components and pressure ratings—look to Hengli for cylinders, pumps, and valves;
Shaoyang Weiketai for high-pressure pumps; and the Yangzhou (Jiangsu) cluster for complete machines.
Match the pressure, displacement, and sealing specifications to your needs before negotiating the price.
