A17FO Series Hydraulic Piston Pump: Selection and Maintenance Guide

The A17FO series fixed-displacement axial piston pump is a high-performance core component built for reliable, efficient operation across mobile and industrial hydraulic systems. Featuring a displacement range of 23 to 107 ml/r, 350 bar continuous rated pressure and 400 bar peak pressure, the product line covers six standard models: A17FO023, A17FO032, A17FO045, A17FO063, A17FO080 and A17FO107. Proper sizing, system compatibility and routine upkeep help operators avoid costly unplanned downtime and extend service life even in harsh working environments.

Core Features and Applications

Engineered with an axial conical piston bent-axis structure, the A17FO series minimizes internal energy loss for highly efficient power transmission. Designed for open-loop hydraulic circuits, it integrates easily into diverse equipment setups. Its robust construction ensures long-term reliability under heavy loads, and it works with a wide range of specification-compliant hydraulic fluids, including environmentally friendly formulations.

Widely used across industries, the series delivers steady hydraulic power for construction machinery (excavators, wheel loaders), agricultural equipment (tillage and harvesting machines) and industrial manufacturing (hydraulic presses, injection molding systems), performing reliably in high-pressure, heavy-duty operations.

Key Selection Factors

1.Flow and pressure requirementsCalculate system flow demand based on actuator needs and operating speed, then select the corresponding displacement model. Ensure continuous working pressure does not exceed 350 bar and transient peak pressure stays within the 400 bar limit to prevent premature wear.

2.System compatibility

Confirm your system uses an open-loop circuit. Verify mounting interfaces, port connections and shaft dimensions for physical fit. Use only hydraulic fluids meeting published performance specifications to avoid efficiency loss and internal component damage.
Environmental and operating conditionsAccount for ambient temperature, humidity and contamination levels, as the pump performs optimally within defined temperature and viscosity ranges. Applications with frequent load fluctuations require appropriately sized models and regular preventive maintenance.

3.Performance Highlights

The fixed-displacement bent-axis design delivers stable energy consumption and high volumetric efficiency, helping reduce running costs. While not equipped with variable displacement technology, correct model selection across the A17FO023 to A17FO107 range optimizes energy use by avoiding oversizing or continuous overload.

Thanks to its heavy-duty structure and low-stress piston design, the series offers exceptional durability. Its 350 bar rated and 400 bar peak pressure capacity supports consistent, reliable performance in high-load applications.

Maintenance Guidelines

Routine inspection

Regularly check for external leaks, seal damage and hydraulic fluid condition. Replace contaminated or oxidized fluid promptly, and clean or replace filters on schedule to maintain unobstructed flow. Keep the pump exterior clean to support proper heat dissipation.

Frequently Asked Questions
