III. Structural Design & Operating Principle
This precision Hydraulic piston pump adopts advanced swash plate adjustment structure. The drive shaft drives the cylinder block to rotate, and changing the swash plate angle adjusts piston reciprocating stroke to realize stepless flow regulation for the hydraulic system.
1. GA6 Load-sensing Control Module: It dynamically matches pump output with actual load demand of the hydraulic system, cutting idle power consumption and restraining pressure shock effectively.
2. 9-Piston Pre-compression Technology: Greatly reduces flow fluctuation of the hydraulic pump, delivering ultra-smooth oil supply to enhance operational precision of high-end hydraulic system.
3. Automatic Wear Compensation: Spherical valve plate achieves self-alignment during rotation, maintaining long-term volumetric efficiency of the hydraulic pump and extending the overhaul cycle of the supporting hydraulic system.
4. Through-shaft Expandable Design: Supports multi-pump combination with other hydraulic pump models, simplifying power expansion layout of complex hydraulic system.
IV. Core Advantages as a Hydraulic Pump & Hydraulic Piston Pump

2. Ultra-low pulsation & low noise: Suitable for precision equipment hydraulic system requiring strict running stability
3. Strong expandability: Through-drive structure enables flexible combination with auxiliary hydraulic pump for customized hydraulic system upgrading
4. Robust durability: Reinforced pump housing and low-friction components adapt to 24-hour continuous heavy-duty operation of industrial hydraulic system
5. Modular maintainability: Standardized spare parts shorten downtime when servicing the hydraulic pump and the whole hydraulic system
6. Wide compatibility: SAE mounting and customizable ports fit global standard hydraulic system retrofitting projects
V. Typical Hydraulic System Application Scenarios
- Locking & injection hydraulic system for small-and-medium injection molding and blow molding machines

- Auxiliary power hydraulic system for light forging, die-casting and tire manufacturing equipment
- Travel & operation auxiliary hydraulic system for compact construction machinery
- Central oil supply hydraulic system for automated production lines, textile and printing heavy machinery
VI. Selection & Operation Guidelines for Hydraulic Systems
1. Calibrate GA6 control parameters according to the pressure and flow curve of your hydraulic system to maximize energy-saving performance of the hydraulic pump
2. Install a precision filter above 10 μm at the inlet to keep oil clean and protect the precision matching parts of the Hydraulic piston pump
3. Limit each peak-pressure duration within 6 seconds to avoid seal failure and component damage of the hydraulic system
4. Select ISO VG32 oil for cold-start hydraulic system, switch to VG46/VG68 for high-temperature heavy-load hydraulic system
VII. Series Matching Tips
- The GA6 control version is more adaptive to variable-load scenarios than basic constant-pressure models, ideal for frequently fluctuating hydraulic system
- PV016-GA6RM1AON can be connected in series with other hydraulic pump via through-drive to expand the power output of the original hydraulic system
- Mounting dimensions follow PV-series unified standards, easy to replace old-fashioned Hydraulic piston pump for on-site hydraulic system renovation
