Key Technical Advantages
1. Three-Piece Cast Iron Construction – High Power Density & Extreme Durability
Featuring Parker’s signature three-piece cast iron construction. The three-piece design provides excellent distribution flexibility, while cast iron material ensures long-term reliability under high-pressure shocks, severe temperature variations, and high-contamination conditions. Ideal for demanding construction, forestry, and oil & gas applications.
2. Balanced Thrust Plates & Journal Bearings – High Volumetric Efficiency & Long Life
Integrated balanced thrust plates minimize friction and internal leakage under high pressure. Paired with journal bearings, friction losses are significantly reduced while extending service life. Volumetric efficiency reaches up to 98%.
3. Bi-Rotational Capability – Maximum Installation Flexibility
The “65” suffix indicates bi-rotational capability. Whether the drive motor/engine rotates clockwise or counterclockwise, the pump can be installed directly—significantly simplifying inventory management and field adaptation.
4. Broad Speed & Temperature Operating Range
Supports speeds up to 3,000 rpm with operating temperature range from -20°C to +80°C. Maintains stable flow characteristics from cold start to high-speed continuous duty.
5. Extensive Integrated Valve Options
The PGP315 series supports integration of multiple control valve functions including: Relief, Load Sense, Priority, and Unloading valves. Flexible configuration reduces external valve groups and piping.
6. Multi-Section Capability & 100% Drop-In Interchangeability
Supports single, tandem, and multiple pump configurations. All models are manufactured to original equipment mounting dimensions and interface standards, ensuring 100% drop-in interchangeability.
7. 100% Simulated Duty-Cycle Testing
Every pump is 100% tested on dedicated hydraulic test benches under simulated real-world operating conditions—validating pressure-flow characteristics and efficiency curves at rated pressure (241 bar) and full speed range—ensuring zero-defect, plug-and-play performance upon installation.

Expert Maintenance Tips
1. Fluid Cleanliness Control
Maintain system fluid cleanliness to ISO 4406 19/17/14 or better. Install a ≤10 μm absolute filtration filter upstream of the inlet port to prevent particle contamination from damaging precision gear pairs, journal bearings, and thrust plates.
2. Inlet Line Requirements
Keep suction lines short and straight with adequate diameter—not less than the port size. Recommended suction line flow velocity: ≤1.5 m/s to prevent cavitation from excessive inlet resistance.
3. Coupling Alignment Precision
Ensure pump shaft-to-drive shaft coaxiality deviation ≤0.05 mm and angular deviation ≤0.5° during installation. Flexible couplings are strongly recommended. If the drive involves sprockets or V-belt pulleys, an independent outboard bearing MUST be installed to protect pump shaft bearings.
4. First-Start Priming Procedure
Before initial startup, prime the pump by bleeding air through the drain port or a loosened outlet fitting. Perform 2–3 jog starts with the outlet open (no load) until oil fills the pump cavity without air bubbles, then connect the load circuit for full operation.
5. Rotation Direction Confirmation
The “65” suffix indicates bi-rotational capability—the pump can be installed with either clockwise or counterclockwise drive rotation. Always verify that the pump nameplate indication matches the actual drive direction before installation.
6. Radial Load Limitations
This model is standard configuration without thru-drive capability. For applications requiring additional radial loads, consult Parker factory for specialized configurations.
