Key Technical Advantages

• High Power Density: The ADY098 delivers a high 98cc output within a frame size typically reserved for smaller pumps, offering designers unparalleled flexibility.

• Low Noise Cradle Swashplate: Utilizing a specialized cradle-type design within a dampened cast-iron housing, the pump minimizes fluid pulsation and noise emission levels.

• Precision Load Sensing: The AD30 compensator provides surgical accuracy in flow matching, ensuring that only the required flow reaches the actuator, reducing heat buildup and fuel consumption.

• Heavy-Duty Bearing System: Equipped with premium tapered roller bearings designed to handle high radial and axial stresses, extending the service life even under extreme duty cycles.

Application Areas

• Construction & Mobile: Primary hydraulic source for wheel loaders, backhoes, and compact excavators.

• Material Handling: Lift and tilt systems for reach stackers, heavy forklifts, and container handlers.

• Industrial HPUs: Hydraulic power units for plastic molding, scrap balers, and metallurgical machinery.

Expert Maintenance Tips

• Mandatory Pre-Fill: Never start the pump dry. Fill the case with clean, filtered hydraulic oil through the highest drain port before the initial startup to protect the internal rotating group.

• Compensator Adjustment: Always use a calibrated gauge when adjusting the pressure limiter on the AD30 controller. Do not exceed the peak rating of 320 bar.

• Contamination Vigilance: To ensure the longevity of the precision-lapped valve plates and piston shoes, maintain fluid cleanliness at ISO 4406 18/16/13 or better.
