All components comply with international standards such as ISO 4401 (hydraulic valve specifications) and ISO 13709 (axial piston pump requirements), providing a comprehensive reference for both procurement decision-making and technical problem-solving.
Axial Piston Pumps
Axial piston pumps serve as the power core of hydraulic systems, converting mechanical energy into hydraulic energy. Premature wear or internal leakage can lead to insufficient system pressure, reduced equipment efficiency, and costly production downtime. Our pumps feature high-strength alloy materials and precision machining, ensuring stable output and long service life, ideal for high-load scenarios like construction machinery and industrial forging equipment.
Field Fault Maintenance Case
A construction site reported frequent stalling of an excavator equipped with the A4VS0250DR/30RPPB13N00 pump. Inspection revealed severe wear of the pump's piston-cylinder pair caused by using hydraulic oil that did not meet ISO 4406 Class 13/10 cleanliness standards. After replacing the pump with our compliant product and upgrading the oil filtration system, the excavator restored normal operation, achieving 3,500+ hours of trouble-free work.
