PD075PS02SRS5AC10S1000000 Parker Hydraulic Pump 75cc 280bar

Model Number	PD075PS02SRS5AC10S1000000, PD075PB01SRS5AAN0S0000000

Product Description

Product Overview

The PD075PS02SRS5AC10S1000000 is a member of Parker Hannifin’s P1/PD Series medium-pressure axial piston variable displacement pumps. With a maximum displacement of 75 cm³/rev (4.58 cu.in/rev), this open-circuit pump delivers continuous operation at pressures up to 280 bar (4060 psi).

Engineered as a premium drop-in replacement for Parker original hydraulic pumps, this unit strictly adheres to Parker P1/PD Series B-mod design standards, ensuring complete interchangeability — no modifications to mounting interfaces, piping connections, or control logic are required for direct replacement of the corresponding Parker OEM model.

Every unit undergoes 100% simulated duty-cycle testing — full performance curve validation under rated pressure, rated speed, and expected operating temperature ranges — guaranteeing volumetric efficiency, response characteristics, and noise levels that meet or exceed Parker factory specifications.

Key Technical Advantages

1. Precision Machining & High-Strength Cast Iron Housing
High-strength cast iron housing combined with precision machining ensures micron-level fit tolerances across all moving components. Pistons and cylinder bores undergo superfinish grinding for optimized clearance and maximum volumetric efficiency. An integral supercharger maintains stable oil intake even at high speeds up to 2400 rpm.

2. High Volumetric Efficiency & Reduced Power Consumption
Hydrostatically balanced slippers and cylinder design minimize internal leakage. Optimized port plate timing delivers up to 98% volumetric efficiency across the full pressure range. Higher operating efficiency means lower power consumption and reduced heat generation, minimizing system temperature rise.

3. Long-Life Bearings & Low-Noise Design
Long-life tapered roller shaft bearings and low-friction, hydrostatically balanced swash plate saddle bearings ensure extended service life. The nine-piston design reduces output flow ripple, while Parker’s proprietary “ripple chamber” technology further attenuates pressure pulsations for significantly lower system noise.

4. Modular Control & Configuration Flexibility
The B-mod design features a unique 5-port control mounting pattern, enabling the same control valve to be used on both clockwise and counterclockwise pumps. Modular control architecture allows for easy on-site control conversions. The PD075PS model is equipped with a remote pressure limiter for remote pressure setting and adjustment.

5. Thru-Drive Capability & Installation Flexibility
Full-power thru-drive capability enables tandem mounting of a second hydraulic pump without additional power input. Three case drain ports support multiple mounting orientations, including horizontal and vertical shaft-up configurations.

Application Areas

Industrial Power Units
Industrial Molding Equipment
Pressing & Stamping Equipment
Water Jet Cutting Systems
Material Handling Equipment
Oil & Gas Industry Equipment
Power Generation Equipment
Top Drive Drilling Systems

Expert Maintenance Tips

1. Case Fill Before Start-up
Prior to first start-up, fill the pump housing with clean hydraulic fluid through the case drain port to ensure pre-lubrication of bearings and rotating components. For vertical shaft-up mounting, bleed air through the D1 drain port located near the mounting flange.

2. Fluid Cleanliness Management
Maintain system fluid cleanliness at or above the rated ISO 20/18/14 requirement. Use return-line filters with minimum 10μm absolute rating (β₁₀≥100) and conduct regular fluid contamination analysis.

3. First Start-up & Pressure Settings
During initial start-up, temporarily reduce compensator and relief valve pressure settings. Gradually increase to operating pressure only after the pump runs smoothly and the system is fully purged of air. Never apply load before complete air bleeding.

4. Viscosity & Temperature Monitoring
Ensure operating fluid viscosity remains within the optimal 14-50 cSt range. Cold starts with transient high viscosity (up to 5000 cSt) are permissible, but loading should only commence after fluid temperature reaches the normal operating range (-40°C to +95°C).

5. Scheduled Inspection & Maintenance
Perform comprehensive performance testing every 2000 operating hours or annually (whichever comes first), including volumetric efficiency testing, response time verification, and noise level assessment. Always use genuine Parker service kits when replacing seals.
