Key Technical Advantages

1. High Power Density with Compact Design – Space-Saving Installation

The P2/P3 series features an optimized envelope and unique port layout, enabling direct mounting on mobile transmission PTOs for fast and cost-effective installation. The compact design delivers exceptional power density within limited installation space, making it the ideal choice for mobile equipment.

2. Built-In Impeller (P3 Series Exclusive) – High Self-Priming Speed & High-Altitude Capability

The P3 series incorporates a built-in impeller for enhanced self-priming capability. The P3105 achieves a self-priming speed of 2600 rpm at 1 bar absolute inlet pressure. This feature makes the P3 series particularly suitable for high-altitude operations or applications with challenging inlet conditions, eliminating the need for external charge pumps.

3. Integrated Pre-Compression Volume – Significant Noise & Pressure Ripple Reduction

Every P2/P3 pump comes standard with an integrated pre-compression volume. This design reduces pressure pulsations by up to 60%, achieving a full-flow noise level of 78 dB(A) (@ 1800 rpm, 250 bar)—delivering low-noise operation without additional silencing components.

4. Flexible Control Options – Energy-Efficient On-Demand Operation

The P2/P3 series offers a wide range of control options including pressure compensation, remote pressure control, load sensing, and torque control. Load-sensing control adjusts flow according to system demand, delivering significant energy savings. Torque limitation effectively manages input power, adapting to equipment with varying flow requirements.

5. Thru-Drive Capability – Supports Multi-Pump Configurations

The P2/P3 series features thru-drive capability, supporting tandem, triple, or even quad pump configurations to supply multiple independent hydraulic circuits simultaneously—greatly simplifying complex hydraulic system layouts.

6. Rugged Cast Iron Construction with Long-Life Design

High-strength cast iron body and precision-machined internal components ensure long-term reliable operation under heavy-duty, high-impact conditions. The modular design facilitates quick and easy maintenance.

Expert Maintenance Tips

Model Code Verification (verify each element):

Before installation, carefully verify the complete model code on the pump nameplate—P3105R00C1C25LA25N 00A1A1P—and confirm the following:

• P3: P3 Series (Supercharged Version), distinct from the standard P2 series.

• 105: Maximum displacement of 105 cm³/rev (P3105 frame size).

• R00: Rotation direction and shaft configuration — “R” indicates clockwise rotation (viewed from shaft end).

• C1: Control type code.

• C25: Pressure setting code.

• LA25N: Port and mounting configuration code.

• 00A1A1P: Additional configuration code (seals, special options, etc.).

Verify Rotation Direction:

“R” indicates clockwise rotation (viewed from shaft end). Confirm that the drive shaft rotation matches the direction code in the model. “L” indicates counter-clockwise rotation. Incorrect rotation will prevent pressure build-up and may damage internal rotating components.

Suction Line & Inlet Pressure Requirements:

Although the P3 series features a built-in impeller, ensure the suction line is properly sealed. The P3105 requires a minimum inlet absolute pressure of 0.9 bar at maximum speed, with maximum inlet absolute pressure not exceeding 1.5 bar. Ensure the suction filter is not clogged and select suction line diameter appropriately based on flow rate.

Case Drain Line Configuration:

The P3 series requires a maximum continuous case drain pressure not exceeding 1 bar. The case drain line must be routed separately back to the reservoir and should not share lines with other return circuits to ensure the housing remains fully filled with oil.

Coupling Alignment Precision:

Ensure shaft concentricity between the pump and drive shaft is within 0.05 mm during installation. Excessive misalignment will cause premature bearing wear, seal leakage, or internal pump damage. Use flexible couplings and dial gauges for precise alignment.

First-Start Priming Procedure:

After new pump installation or system overhaul, perform priming before first start. Jog the pump at low pressure (not exceeding 50 bar) and low speed (approx. 600 rpm) until the pump body is fully filled with oil and air is purged, then gradually increase to rated speed and working pressure. The swashplate should be set to minimum displacement during start-up to reduce starting shock. Running the pump dry will cause irreversible damage to pistons and cylinder barrel due to metal-to-metal contact.

Oil Cleanliness Management:

P2/P3 series axial piston pumps have high requirements for oil cleanliness. Hydraulic oil with cleanliness not lower than ISO 4406 18/16/13 is recommended, with filtration rating β10 ≥ 75. Regularly inspect return filter condition and replace hydraulic oil and filters per equipment manufacturer recommended intervals.

Regular Maintenance & Temperature Monitoring:

Inspect pump operating condition every 1,000 operating hours. Regularly monitor pump body temperature—if it consistently exceeds +80°C, inspect the system cooling and relief valve settings. Listen for abnormal noise or vibration during operation; if detected, shut down and troubleshoot immediately.
