Hydraulic Power Core: Wantong Power Unit Solves Equipment-Driving Challenges

Recently, Shandong Wantong Hydraulic Co., Ltd., a national-level "Little Giant" enterprise specializing in niche and innovative products (hereinafter referred to as "Wantong Hydraulic"), announced that its independently developed hydraulic power unit has entered mass production. Featuring "integration, miniaturization, and high efficiency with energy savings" as its core advantages, the product is widely compatible with applications such as hydraulic machine tools, compact construction machinery, medical equipment, and automated production lines, providing a stable power source for hydraulic systems.

According to the head of Wantong Hydraulic R&D Center, the hydraulic power unit features an integrated design that combines a motor, hydraulic pump, oil tank, and control valve group. This compact configuration significantly reduces the unit's overall volume compared to conventional split-type power units, making it easier to integrate and install into equipment. The motor is equipped with a high-efficiency permanent-magnet synchronous motor, offering power output ranging from small to medium capacities—and delivering a notable energy-saving advantage over asynchronous motors. Meanwhile, the hydraulic pump can be either a gear pump or a piston pump, selected based on specific operational requirements, with rated pressures spanning from low-to-medium to high-pressure ranges, and flow rates covering a wide variety of commonly used applications. The control valve group integrates overflow valves, directional control valves, and check valves, minimizing pipeline connections and thereby reducing the risk of leakage. Additionally, the power unit can be customized to meet specific equipment needs, including options for oil tank capacity (ranging from small to medium sizes) and control methods (manual or electrically controlled), ensuring optimal compatibility with the power demands of diverse hydraulic systems.

Enterprise Strength: R&D and Testing Capabilities

As one of the first companies listed on the Beijing Stock Exchange, Wantong Hydraulics boasts a dedicated R&D team specializing in power units, equipped with end-to-end development capabilities spanning motor selection, pump-valve matching, and system integration. The company has already secured multiple patents related to its power unit technology. Additionally, Wantong has established a specialized testing platform for power units, capable of conducting no-load tests, load tests, noise assessments (with operational noise levels kept impressively low), and thousands-of-hour durability tests—ensuring that its products perform reliably across a wide range of temperature conditions, from extremely cold to high-heat environments. Leveraging its "Hydraulic Power Unit Production Line," the company can meet the bulk procurement demands of hydraulic equipment while maintaining a remarkably short delivery cycle.

Market Application: Multi-Scenario Power Needs Met

At a hydraulic machine tool factory in Zhejiang, multiple CNC hydraulic punch presses equipped with Wantong Hydraulic Power Units have been running smoothly for several months. These machines have seen improved processing efficiency, significantly reduced energy consumption, and reliable, fault-free operation of the power units—resulting in maintenance costs that are notably lower than those of the original equipment. "Hydraulic machine tools demand high stability and energy efficiency from their power units, and Wantong’s products have far exceeded our expectations," said the factory’s production director. Additionally, the same product line has also been adopted by a medical device company in Jiangsu, where it powers hydraulic surgical beds, perfectly suited to the quiet and stable operational environment required in operating rooms.

The Marketing Director of Wantong Hydraulics stated that as hydraulic equipment evolves toward "miniaturization and energy efficiency," the demand for power units will continue to grow. Moving forward, the company plans to develop power units equipped with intelligent variable-frequency technology, further enhancing energy-saving performance and better meeting the needs of new-energy hydraulic systems.
