A Series High-Performance Axial Piston Variable Displacement Pump

Product Overview: The A Series is a range of high-efficiency, low-noise axial piston variable displacement pumps engineered specifically for Open Circuit industrial hydraulic systems. Known for their exceptional reliability and compact footprint, these pumps are staples in plastic injection molding machines, metalworking tools, stamping presses, and various automated hydraulic power units (HPUs). Core models such as A10-F-R-01-C-K-10 and A16-F-R-01-C-K-32 utilize classic pressure compensator logic, automatically modulating flow once the set pressure is reached to significantly reduce energy consumption and prevent system overheating.

Key Technical Advantages:

• Superior Energy Efficiency: Equipped with high-sensitivity Type 01 Control (Pressure Compensator). Once the system hits the preset pressure (e.g., C-range 1.5-21 MPa), the pump reduces displacement to the minimum required to maintain pressure, eliminating unnecessary overflow loss.

• Low Noise & Low Vibration Design: The A Series features acoustically optimized internal components and a heavy-duty cast iron housing. Even at peak pressure, its decibel levels remain well below industry averages, making it ideal for modern factories with strict noise regulations.

• High Response & Long Service Life: Utilizing specially treated piston groups and spherical port plate designs, these pumps ensure rapid response times during frequent start-stop cycles and high-pressure operations, significantly extending MTBO (Mean Time Between Overhauls).

• Flexible Mounting Specifications: Offers multiple mounting styles (F: Flange, L: Foot) and shaft configurations. Suffixes like K (Keyed Shaft) and design sequence numbers 10/32 ensure 100% physical compatibility with OEM standards.
