Top 10 Hydraulic Pump Manufacturers in China: A Practical 2026 Buyer’s Guide

Finding a hydraulic pump manufacturer in China is easy. Finding one that can match your technical requirements, deliver consistent quality, support your documentation needs, and remain dependable after the first shipment is much harder.

For OEMs, distributors, repair specialists, and hydraulic system builders, a supplier list is only the starting point. The real decision depends on pump type, operating pressure, control method, mounting dimensions, quality validation, lead time, and long-term spare-parts support.

This guide introduces ten China hydraulic pump manufacturers and explains how buyers should evaluate them. It is not a universal "best-to-worst" ranking. Different suppliers serve different applications, and the right partner for a compact power unit may not be suitable for a high-pressure excavator drive system.

Quick Comparison: 10 Hydraulic Pump Manufacturers in China

1. Bohang Hydraulic

Bohang Hydraulic is a strong option for buyers seeking high-pressure piston pumps, hydraulic motors, valves, spare parts, and application-specific hydraulic solutions. Its product range is positioned around Rexroth-compatible configurations for mobile and industrial equipment, including A10VO, A4VSO, A4VG, A6VM, A2FM, and A2FO series.

For example, its A10VO series is specified from 18 to 140 cm³/rev with 280 bar nominal and 350 bar peak pressure, while its A4VSO range extends from 40 to 1,000 cm³/rev at up to 350 bar nominal pressure. This makes Bohang particularly relevant for equipment builders, distributors, and repair specialists who need to match a pump by displacement, pressure, mounting interface, and control type.

Bohang is best suited to projects where technical compatibility, customized selection, and cost control matter as much as the initial unit price. Buyers should submit the complete model number, nameplate photo, circuit type, pressure, displacement, and installation dimensions for review.

2. Hengli Hydraulic 

Hengli Hydraulic is a large-scale Chinese manufacturer with hydraulic pumps, motors, cylinders, valves, electronic controls, precision castings, and system-integration capabilities. Its public product range covers both open-circuit and closed-circuit pumps, making it relevant to buyers of construction machinery, agricultural machinery, mining equipment, marine equipment, and industrial machinery.

For larger OEM programs, Hengli's advantage is product breadth. Buyers can potentially source more than one hydraulic subsystem from one manufacturing group, which may simplify engineering coordination and supply-chain management. The company states that it operates 12 manufacturing bases and seven R&D centers worldwide.

3. Jiangsu Guorui Hydraulic Machinery (GRH) 

GRH has a broad hydraulic component portfolio covering external gear pumps, gear motors, orbital motors, proportional valves, sectional valves, manifolds, power units, and hydraulic systems. Its application pages focus on agricultural machinery, construction machinery, handling equipment, marine winches, aerial work platforms, and municipal vehicles.

This makes GRH particularly useful for buyers who need compact hydraulic power packs, gear-pump-based systems, or a coordinated combination of valves, motors, and pumps. The company also presents itself as a system supplier rather than only a component vendor.

GRH is a practical candidate for distributors and OEMs sourcing mobile hydraulic components in volume. Buyers should confirm whether the selected product is designed for continuous industrial duty, mobile duty, or a specific vehicle application. 

4. Ningbo Hilead Hydraulic

Ningbo Hilead Hydraulic focuses on high-pressure axial piston pumps, hydraulic motors, hydraulic systems, and hydraulic machinery. Its stated application coverage includes construction, metallurgy, machine tools, marine equipment, petrochemical equipment, agriculture, automotive, mining, aerospace, and defense-related industries.

For buyers of high-pressure piston-pump systems, its axial-piston specialization is the key point. The company states that it develops A4V and A10V axial piston pump technologies and has production, R&D, and testing capabilities for high-pressure and large-displacement products.

5. Huade Hydraulic Technology

Huade Hydraulic Technology offers directional valves, pressure valves, flow-control components, cartridge valves, proportional valves, hydraulic pumps, motors, equipment, and castings. Its product structure is particularly relevant to system builders that need pump-and-valve matching rather than a pump-only purchase.

The company presents applications in filter presses, plastics machinery, water-conservancy equipment, mobile machinery, and marine engineering. For an industrial buyer, the benefit is the ability to discuss control logic, pressure control, flow regulation, and pump selection with one supplier.

Huade is best considered for industrial hydraulic circuits where valves play a major role in system performance. Buyers should verify the selected pump/motor product line separately, because the company's visible product depth is especially strong in hydraulic control valves. 

6. Qidong Deke Hydraulic Machinery 

Qidong Deke Hydraulic Machinery specializes in hydraulic oil pumps and lists a range of commonly requested piston-pump and motor families, including A2F, A2FE, A2FM, A7V, A6V, A4VSO, A10VSO, and PV2R vane pump series.

Its main advantage for aftermarket buyers is model familiarity. When an importer, repair workshop, or equipment owner needs to source a replacement unit based on an established series number, a supplier with this type of portfolio can make initial matching easier.

This is most relevant to replacement and repair sourcing. Buyers should never rely on series names alone: shaft type, mounting flange, port arrangement, rotation direction, controller, seals, and operating pressure must all be checked.

7. Qidong Hengyu Hydraulic Equipment 

Qidong Hengyu Hydraulic Equipment presents axial piston pump series including CY14-1B and HY ranges. This makes it relevant to buyers looking for established Chinese axial-piston-pump formats used in industrial machinery and hydraulic power systems.

Its potential advantage is a focused product selection for buyers who already understand the pump series they need. This is useful in maintenance replacement, legacy equipment repair, and applications where the original drawing or model code is available.

Before ordering, buyers should request a data sheet showing displacement, rated pressure, peak pressure, speed range, efficiency, case-drain requirements, and installation dimensions. A series-level match is only the first step in proving functional interchangeability.

8. Liyuan Hydraulic 

Liyuan Hydraulic positions itself as an experienced developer and manufacturer of high-end core hydraulic components, with a focus on axial piston pumps and motors. Its public profile highlights more than 60 years of R&D and manufacturing experience.

For buyers, long-term product development experience can be relevant when the project demands deeper technical discussion, higher pressure capability, or a more established engineering base. It may be especially suitable for industrial users looking beyond simple commodity replacement parts.

Buyers should investigate current product availability, export support, documentation language, and the exact pump/motor series offered for their application.

9. Boxinhuasheng Hydraulic

Boxinhuasheng Hydraulic supplies hydraulic gear pumps, piston pumps, directional control valves, and PTO units for mobile and industrial machinery. Its website states that it supports OEM/ODM customization, operates multiple manufacturing plants, and conducts workload simulation tests before shipment.

Its broader strength is the combination of gear pumps, valves, and truck/mobile-hydraulic components. This can be valuable to distributors and vehicle-equipment manufacturers that need product breadth, rather than only high-pressure axial piston pumps.

The supplier may be a good fit for tipping systems, mobile equipment, truck hydraulics, and standard OEM component programs. Buyers should confirm whether the required pump is suitable for the application's actual flow, pressure, duty cycle, and fluid conditions.

10. Kunjoho

Kunjoho presents itself as a supplier of axial piston, vane, and gear pumps, orbital motors, hydraulic assemblies, and spare parts. It highlights OEM/ODM support, in-house testing, pressure/flow/leakage checks, and product lines for construction, agriculture, material handling, mining, marine, and industrial equipment.

For buyers who need a mixed order involving several pump types or motor assemblies, this broad range can be useful. It is also relevant to aftermarket distributors that need a flexible portfolio rather than a single pump family.

Buyers should ask for product drawings, quality records, production location, sample lead time, and confirmation of compatibility before placing a bulk order. 

What Makes a Good Hydraulic Pump Manufacturer?

A serious hydraulic pump manufacturer should be evaluated on more than price and catalogue appearance. The most useful questions are practical:

• Can the supplier match the required pressure, displacement, rotation direction, control type, shaft, flange, and port configuration?
• Can it provide a drawing, data sheet, and test record before production?
• Does it have machining, assembly, inspection, and testing capability?
• Can it support pilot samples, repeat orders, spare parts, and technical troubleshooting?
• Is its product suitable for your application duty cycle rather than only for a short demonstration test?

For positive-displacement pumps and motors, ISO 4409:2019 defines methods for determining and presenting steady-state performance and efficiency. Buyers do not need to become test engineers, but they should ask what conditions were used to test pressure, speed, temperature, flow, and leakage. A supplier that cannot explain its test conditions is difficult to qualify for an OEM project.

Mounting compatibility matters just as much. ISO 3019-2 covers metric mounting flanges and shaft ends for rotary positive-displacement pumps and motors, while SAE J744 addresses mounting and drive dimensions for hydraulic pumps and motors used on off-road work machines. Matching only a product’s external appearance is not enough.

How to Choose the Right China Hydraulic Pump Manufacturer

Start With the Application, Not the Brand Name

The first step is to define where the pump will work. A pump used in a loader, excavator, paver, or concrete mixer must handle dynamic loads, frequent speed changes, shock pressure, and demanding field conditions. A pump for injection molding, die casting, CNC equipment, or a hydraulic power unit may place more emphasis on flow stability, energy efficiency, noise control, and continuous operation.

Buyers should provide the following information with an RFQ:

1. Existing pump model or a clear nameplate photo
2. Required displacement and operating speed
3. Nominal and peak pressure
4. Open-loop or closed-loop circuit type
5. Shaft, mounting flange, and port dimensions
6. Control method and direction of rotation
7. Hydraulic fluid, operating temperature, and cleanliness target
8. Annual quantity, sample requirement, and target delivery date

This information lets the supplier assess compatibility before giving a price. It also reduces the risk of receiving a pump that fits physically but cannot perform correctly in the system.

Check the Product Range and Technical Depth

A broad catalogue can be useful, but it should not replace technical focus. For example, a supplier of low-pressure gear pumps may not be the best choice for high-pressure variable piston pumps. Similarly, a company that sells hydraulic parts may not be able to provide the engineering support needed for an OEM replacement project.

Bohang Hydraulic focuses on piston pumps, motors, valves, spare parts, and custom solutions for hydraulic transmission systems. Its published range includes models commonly used in mobile and industrial hydraulics:

• The A10VO variable pump range covers 18 to 140 cm³/rev, with 280 bar nominal pressure and 350 bar peak pressure.
• The A4VSO heavy-duty variable pump range covers 40 to 1,000 cm³/rev, with 350 bar nominal pressure and 400 bar peak pressure.
• The A6VM variable motor range covers 5 to 1,000 cm³/rev, with 400 bar nominal pressure and 450 bar peak pressure.

These figures do not automatically make one product suitable for every machine. They show why buyers must compare actual operating conditions against the selected model’s specifications. A pump should be selected for the real duty cycle, not simply for its highest advertised pressure rating.

For product comparison, buyers can review Bohang's hydraulic pump range and hydraulic motor range before submitting an RFQ.

Manufacturing Quality: What to Verify Before You Order

A reliable manufacturer should be ready to discuss how quality is controlled, not simply state that quality is "high."

Ask for evidence of:

• Incoming inspection for castings, bearings, seals, and critical parts;
• Machining and dimensional inspection processes;
• Assembly cleanliness controls;
• Functional, pressure, leakage, and efficiency testing;
• Final inspection records and traceability;
• Packaging methods suitable for export transport;
• Warranty terms and spare-parts availability.

Fluid cleanliness should also be part of the conversation. ISO 4406:2021 provides a coding method for the level of solid particle contamination in hydraulic fluid. In practice, the required cleanliness level depends on component design, application, and system requirements. Buyers should ask both how a pump is protected during production and what filtration or fluid cleanliness conditions are recommended during operation.

This is especially important for variable piston pumps, proportional control systems, and high-pressure components. Poor contamination control can shorten component life even when the pump itself is correctly specified.

Application Matters: Examples for Buyers

For construction machinery, buyers should prioritize peak-pressure capability, load response, durability, service access, and compatibility with travel or work circuits.

For industrial equipment, important factors often include stable flow, low noise, thermal performance, controllability, and energy efficiency.

For port, marine, and offshore equipment, buyers should consider corrosion resistance, heavy-duty operating conditions, continuous service requirements, and spare-parts planning.

For agricultural machinery, the focus may be compact installation, efficient load-sensing control, steering performance, and dependable field service.

Bohang's application coverage includes construction machinery, agricultural machinery, industrial equipment, municipal vehicles, port equipment, marine projects, and wind-power-related hydraulic applications. Review the relevant hydraulic application scenarios before choosing a component series.

Common Sourcing Mistakes

The most expensive sourcing errors are usually preventable:

• Choosing only by the lowest quotation;
• Assuming two visually similar pumps are interchangeable;
• Ignoring control type, shaft, flange, ports, and rotation direction;
• Ordering bulk quantities before testing a sample;
• Accepting unsupported certification claims;
• Failing to confirm warranty, lead time, and spare-parts support;
• Treating a supplier list as a final purchasing decision.
