South Korea remains a global powerhouse in construction equipment, shipbuilding, and automotive manufacturing. With giants like Hyundai Construction Equipment and Develon (formerly Doosan Infracore) leading the charge, the demand for high-precision hydraulic components—specifically the A11V Series—has reached an all-time high.
In the "Smart City" era of Incheon and Sejong, machinery requires hydraulic pumps that offer not just power, but "Intelligent Displacement." Our A11V series serves as the heart of these machines, providing variable flow that adapts to real-time load requirements, a critical feature for the efficiency-driven Korean market.
Compatibility with Korean-made Excavators
Energy Efficiency Increase via A11VLO Load Sensing
Hydraulic Export Volume to East Asia
Delivering Information Gain through supply chain transparency and technical superiority.
We use vacuum-degassed steel for our swashplates, ensuring 50% longer lifespan compared to standard cast iron variants common in the market.
Our CNC facilities utilize German-made grinders to achieve sub-micron tolerances (0.001mm), ensuring leakage-free operation under 350-bar pressure.
Located in Qingdao/Shandong, we are a 24-hour ship-route away from Incheon Port. We offer the fastest response time for Korean distributors.
We don't just sell pumps; we provide 1:1 replacement solutions for original Bosch Rexroth units, tailored with Korean-specific porting and mounting.
Our A11V pumps power deck machinery and winch systems for bulk carriers, offering high corrosion resistance against salty sea air.
For high-speed rail and tunnel boring machines (TBM), our pumps provide the constant pressure needed for heavy rock excavation.
Eco-friendly hydraulic solutions for orchard tractors, minimizing oil leaks and maximizing fuel economy.
Weitai Hydraulic is one of China’s leading hydraulic suppliers, the earliest hydraulic enterprises which specializing in export business for decades. We are committed to providing excellent hydraulic products and services to both businesses and final users worldwide.
At the first beginning, we are OEM factory, and have gradually developed into a comprehensive company integrating production, trade and investment. Hydraulic motors are one of our main products. In addition to our own hydraulic factories, we are a shareholder of a high-quality hydraulic motor manufacturer. Our factories are all ISO certified and our material suppliers have all obtained CE, RoHS, CSA and UL certificates.
The Motor products include but are not limited to travel motors, swing motors and wheel-motors. Our motors have an advanced design structure and provide high volume efficiency, high strength and good stability which far superior than our competitors’ motors. In 2019, we produced over 40,000 travel motors, serving giants like SANY, XCMG, and SDLG.
The A11VLO series is designed with a swashplate design for hydrostatic drives in open circuit hydraulic systems. It features a displacement range from 40cc to 260cc, capable of nominal pressures up to 350 bar and peak pressures reaching 400 bar.
For the Korea market, we have optimized the LR3 control system. This power control with a remote-controlled pressure cut-off ensures that even under the extreme cold of Gangwon-do winters or the humid heat of July, the pump's response time remains within <20ms. This prevents the "jerky" motion often found in cheaper hydraulic pumps, protecting the mechanical integrity of the excavator arm.
HD, EP, DR, LR, and LG variants available for immediate shipping.
Standardized with Viton seals for superior temperature resistance.
Compatible with adding gear pumps or axial piston pumps of the same size.
100% full-load dynamic test before dispatch (test report included).
A: Yes. Our A11VLO and A11VO series are 100% interchangeable with Rexroth in terms of mounting dimensions, performance parameters, and spare parts. We follow the same ISO mounting standards.
A: For in-stock items, we can ship within 3-5 days. For custom OEM orders, production typically takes 15-25 days. Shipping from Qingdao to Korea takes only 1-2 days by sea.
A: We provide a 12-month comprehensive warranty. Technical support is provided via 24/7 video consultation, and we have local partners in Korea who can assist with on-site diagnostics if required.
A: Absolutely. Our factories are ISO9001 certified, and our products carry CE, RoHS, and UL certificates, ensuring they meet the strict safety and environmental standards of the Korean industrial sector.
