Premature wear, internal leakage, or flow instability 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, high pressure resistance, and long service life, ideal for high-load scenarios like construction machinery and industrial forging equipment.
Field Fault Maintenance Case
A mining site reported that a hydraulic loader equipped with the A4VS0250DR30RPPB13N00 pump experienced frequent pressure drops. 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 loader restored stable operation, achieving 4,500+ hours of trouble-free work.
