P1060PD04SRM5BC00T00B000 Parker Piston Pump 60cc 280bar

Product Overview

The P1060PD04SRM5BC00T00B000 is a Parker Hannifin P1/PD Series open-circuit swashplate-type axial piston variable displacement pump. The P1 Series is Parker’s compact variable pump line for medium-pressure open-circuit mobile applications, with displacements ranging from 18 to 140 cm³/rev. This model delivers a maximum displacement of 60 cm³/rev.

This model features PD04 control—Pressure Compensator control. The pressure compensator automatically adjusts the swashplate angle in response to system pressure changes, reducing displacement when the set pressure is reached to maintain constant system pressure. SRM5B is the shaft, mounting flange, and port configuration code. C00T00B000 is the seal material, rotation direction, and production batch code.

As a direct OEM-equivalent replacement solution for the Parker P1 Series, this product offers complete in-situ interchangeability, strictly adhering to Parker’s original design specifications and mounting interface standards. Every unit undergoes 100% simulated duty-cycle testing, ensuring that key performance metrics—including volumetric efficiency, pressure-flow characteristics, and case drain flow at rated pressure and full displacement—meet or exceed original factory specifications.

Key Technical Advantages

1. Compact Design for Space-Constrained Installations
The P1060PD04SRM5BC00T00B000 features a compact overall package size, enabling installation in space-constrained mobile equipment engine compartments. The small envelope size makes it particularly suitable for loaders, excavators, and other mobile machinery with stringent installation space requirements.

2. Pressure Compensator Control for Stable and Reliable System Pressure
The PD04 control features a Pressure Compensator that automatically adjusts the swashplate angle in response to system pressure changes. When system pressure reaches the set point, the pump reduces displacement to only the small flow required to maintain pressure, significantly reducing overflow losses and system heat generation for energy-efficient operation. Adjustment range covers 26–280 bar (380–4060 psi).

3. 350 bar Peak Pressure with 9-Piston Low-Noise Design
The P1060 delivers a continuous operating pressure of 280 bar with peak pressures up to 350 bar. The 9-piston design effectively reduces flow pulsation and pressure ripple, while the unique Ripple Chamber Technology significantly reduces operating noise, improving operator working conditions.

4. Full Power Thru-Drive Capability for Flexible Multi-Pump Expansion
The P1 Series features 100% full power thru-drive capability as standard. This design enables the P1060PD04SRM5BC00T00B000 to serve as the lead pump in multi-pump systems, providing drive power for subsequent pump stages and significantly simplifying system layout while saving installation space.

5. Elastomer Seals and Taper-Roller Bearings for Extended Service Life
The P1 Series features elastomer seals that eliminate gaskets and external leakage. Taper-roller shaft bearings and hydrostatically balanced swashplate saddle bearings deliver excellent load capacity and extended service life.

Application Areas

• Wheel Loaders: Hydraulic power for implement and steering systems

• Excavators: Main pump for small to medium excavator hydraulic systems

• Forklifts: Hydraulic power units for material handling equipment

• Agricultural Machinery: Hydraulic systems for combine harvesters and tractors

• Vocational and Municipal Equipment: Refuse compactors, sweepers, etc.

• Forestry Equipment: Hydraulic systems for feller bunchers and skidders

Expert Maintenance Tips

1. Model Confirmation & Pre-Installation Inspection: Prior to installation, confirm the complete model code as P1060PD04SRM5BC00T00B000. The pump supports horizontal or vertical (shaft-up) mounting. Verify that the mounting flange specification and shaft type match the host machine PTO interface. Manually rotate the shaft before installation to confirm smooth, obstruction-free rotation.

2. Fluid Cleanliness Control: Use high-quality hydraulic oil meeting Parker specifications. A minimum filtration rating of ISO 18/15 is recommended. Complete system flushing is mandatory before initial start-up.

3. Pressure Compensator Tuning: The PD04 control features pressure compensator control. The compensator pressure set point can be adjusted via the adjustment bolt, with an adjustment range of 26–280 bar (380–4060 psi). Perform initial settings under no-load conditions, then gradually increase load to target pressure with fine adjustments.

4. Initial Start-Up & Priming: Before first start-up, pre-lubricate the pump by filling the housing with clean hydraulic fluid through the case drain port. Perform a brief jog start (5–10 seconds) to check for abnormal noise, leakage, or excessive vibration. Then正式 start the pump and run at low load for several minutes to purge air from the pump and system lines. Ensure the shaft end is oriented upward during first start-up for proper priming and housing fill.

5. Case Drain Port Positioning & Pressure Monitoring: The P1 Series housing features multiple drain ports for various mounting orientations. During installation, ensure at least one drain port is positioned higher than the pump body to prevent oil starvation in the pump chamber after shutdown. Continuous case pressure must not exceed 2 bar absolute, with peak case pressure not exceeding 4 bar absolute.

6. Scheduled Maintenance & Filter Replacement: Follow the maintenance intervals specified in the Parker P1/PD Series Service Manual (Bulletin HY28-2708-02/SVC/EN). Pay particular attention to filter condition, fluid cleanliness, and seal integrity during routine inspections.

Model 2: P1140PS01SRM5BAM0T00B0000

Product Overview

The P1140PS01SRM5BAM0T00B0000 is a Parker Hannifin P1/PD Series open-circuit swashplate-type axial piston variable displacement pump.

Expert Maintenance Tips

1. Model Confirmation & Pre-Installation Inspection: Prior to installation, confirm the complete model code as P1140PS01SRM5BAM0T00B0000. This is the largest displacement model in the P1 Series, weighing approximately 75–82 kg—ensure lifting equipment and mounting brackets have adequate load capacity. The pump supports horizontal or vertical (shaft-up) mounting. Verify that the mounting flange specification and shaft type match the host machine PTO interface. Manually rotate the shaft before installation to confirm smooth, obstruction-free rotation.

2. Fluid Cleanliness Control: Use high-quality hydraulic oil meeting Parker specifications. A minimum filtration rating of ISO 18/15 is recommended. The P1140’s large displacement (140 cc) means higher flow rates and more demanding lubrication requirements. Complete system flushing is mandatory before initial start-up.

3. PS01 Controller Tuning: The PS01 control configuration integrates load sensing and pressure limiter functions. During commissioning, note the following:

   • Load Sensing Setting: Set the LS differential pressure (10–30 bar / 145–435 psi) based on maximum system load demand

   • Pressure Limiter Setting: Set the cut-off value based on maximum system working pressure (80–280 bar / 1160–4060 psi)
     Perform initial settings under no-load conditions, then gradually increase load to target operating conditions with fine adjustments.

4. Initial Start-Up & Priming: Before first start-up, pre-lubricate the pump by filling the housing with clean hydraulic fluid through the case drain port. Perform a brief jog start (5–10 seconds) to check for abnormal noise, leakage, or excessive vibration. Then正式 start the pump and run at low load for several minutes to purge air from the pump and system lines. Ensure the shaft end is oriented upward during first start-up for proper priming and housing fill.

5. Case Drain Port Positioning & Pressure Monitoring: The P1 Series housing features multiple drain ports for various mounting orientations. During installation, ensure at least one drain port is positioned higher than the pump body to prevent oil starvation in the pump chamber after shutdown. The P1140’s large displacement means higher case drain flow—ensure the drain line has adequate diameter. Continuous case pressure must not exceed 2 bar absolute, with peak case pressure not exceeding 4 bar absolute.

6. Scheduled Maintenance & Filter Replacement: Follow the maintenance intervals specified in the Parker P1/PD Series Service Manual (Bulletin HY28-2708-02/SVC/EN). Pay particular attention to filter condition, fluid cleanliness, and seal integrity during routine inspections. The P1140’s large displacement design means larger rotating group components with higher load demands—requiring higher maintenance quality.
