ABOUT H-STAR

Guangzhou Huasheng Construction Machinery Co., Ltd. is a manufacturer and global supplier of hydraulic pumps, hydraulic components and engine parts for construction, agricultural and industrial machinery.
H-STAR is the professional foreign trade company and brand under Huasheng, dedicated to providing global customers with a more reliable and efficient sourcing solution through our production workshop, assembly capability, testing equipment, warehouse and quality-control process.
We supply products for excavators, bulldozers, wheel loaders, tractors, concrete pump trucks, mixer trucks and other heavy equipment.
More Than a Parts Supplier
We understand that purchasing machinery parts is not simply about finding a product with a similar appearance.
The correct part number, machine model, mounting dimensions, ports, configuration and application must be carefully checked before shipment.
For this reason, our team reviews the information provided by customers and helps confirm product compatibility before an order is finalized.
Customers can send us:
Part numbers
Nameplate photos
Machine models
Product photos
Dimensions
Existing product information
Our goal is to reduce incorrect orders, installation problems and unnecessary purchasing risks.

To improve regional communication and customer support, we have a local office in Brazil and a local representative network in Russia.
Our Brazil team supports regional customer communication, order coordination and after-sales follow-up for South American customers.
Our local representative in Russia helps improve communication and regional service for Russian-speaking customers.

As an integrated industrial and trading enterprise, Huasheng combines manufacturing capability with global supply chain experience. We operate through H-STAR — our dedicated international trading division — to serve overseas markets with specialized expertise and localized support.
Our technical team and experienced international trade specialists work together to deliver reliable products and efficient service for our global partners.
Global Brands We Support
We supply replacement parts and components for the world's leading construction machinery brands, including:
Kubota — engines, hydraulic systems, and precision components
Caterpillar — heavy-duty hydraulic pumps and engine assemblies
Komatsu — complete hydraulic and powertrain solutions
Danfoss — high-performance hydraulic pumps and system components
Epiroc — specialized parts for mining and tunneling equipment
Our product range is engineered to meet or exceed OEM specifications, ensuring seamless integration and consistent performance across all major equipment brands.
Hydraulic Systems — The Core Power of Construction Machinery
Hydraulic systems drive every movement — from boom lifting to bucket tilting. Huasheng provides a comprehensive range of hydraulic pumps and pump accessories, engineered for stable performance, precise control, and extended service life.
Our hydraulic product line includes:
Hydraulic pumps — axial piston pumps, gear pumps, and variable displacement pumps
Pump accessories — control valves, seal kits, swashplates, cylinder blocks, and pressure regulators
Hydraulic system components — motors, filters, and cooling units
Every hydraulic component we supply is developed to withstand demanding working conditions — high pressure, temperature fluctuations, and continuous heavy-duty operation. Whether for excavators, loaders, bulldozers, or concrete pumps, our hydraulic solutions keep machines moving.
Engine Assemblies and Components — Power That Lasts
Engine performance determines machine productivity and operating cost. Huasheng supplies complete engine assemblies and engine components built to maintain consistent power output in the toughest environments.
Our engine product range includes:
Complete engine assemblies — drop-in replacements for major brands
Engine components — cylinder heads, pistons, rings, injectors, fuel pumps, turbochargers, and gasket kits
Cooling and lubrication system parts — radiators, oil coolers, and filtration elements
All engine parts are manufactured to precise tolerances, ensuring reliable starting, smooth operation, and long service intervals — even under extreme loads.
Protecting What Matters — Sealing Solutions
Sealing solutions are essential for protecting hydraulic and engine systems from contamination and pressure loss. Our sealing products are manufactured from high-grade materials designed to withstand high pressure, extreme temperatures, and abrasive environments.
From O-rings and oil seals to full gasket sets and rotary shaft seals, our sealing solutions help extend equipment life, reduce fluid consumption, and minimize maintenance costs — critical factors for fleet operators working in remote or harsh locations.
Global Reach with Local Support
Today, Huasheng products are trusted by customers across Latin America, South America, and North America — markets where our presence and expertise are deeply established.
We maintain a dedicated business unit in Brazil, providing:
Local-language support and technical consultation
Faster response times for urgent inquiries
On-site inspection and pick-up options for Brazilian customers
While our Brazil office offers convenient local access, our international trading division H-STAR is positioned to deliver even broader supply options, competitive pricing, and flexible logistics arrangements for customers across all markets. For the most comprehensive support and the most competitive solutions, working directly with our global team ensures you get the full strength of our supply network.
Strategic Warehousing — Ready When You Are
We operate large-scale warehouses and manufacturing facilities strategically located across China's major ports, enabling faster consolidation, shorter shipping times, and lower freight costs for bulk buyers.
This infrastructure advantage means:
Bulk orders are processed and shipped with minimal lead time
Urgent spare-parts demands are met through strategically positioned inventory
Large-scale procurement benefits from reduced logistics complexity and cost efficiency
Whether you are a distributor, repair workshop, or equipment owner, our organized warehouse management and efficient logistics coordination ensure you get what you need — when you need it.

Customization Services:
Labeling — custom logo printing and branded packaging
Engraving / Laser Marking — part numbers, specifications, or branding directly on components
Packaging — customized packaging solutions for retail-ready presentation or bulk shipment
One-Stop Solutions for Bulk Buyers:
