Key Technical Advantages
1. 280 bar Continuous Operating Pressure – Reliable Power for Medium-Pressure Systems
The PD045 delivers stable continuous operation at 280 bar (4,060 PSI), providing reliable pressure oil for medium-pressure hydraulic systems. With 45 cm³/rev displacement and 1,800 rpm speed, it delivers 81 L/min flow with excellent power density.
2. Compact Design for Maximum Installation Flexibility
The P1/PD series features a compact overall package size, delivering high power density in a limited footprint. The SAE B two-bolt flange simplifies assembly for space-constrained equipment.
3. Low-Noise Nine-Piston Design with Ripple Chamber Technology
The nine-piston design combined with unique “ripple chamber” technology effectively reduces pressure pulsation and operating noise. Maximum noise level is only 83 dBA, making it ideal for indoor environments with strict noise restrictions.
4. Long-Life Bearings and Hydrostatically Balanced Swashplate Bearings
Long-life roller shaft bearings and low-friction hydrostatically balanced swashplate saddle bearings significantly reduce wear on critical friction pairs, extending pump service life. The hydrostatic balance design forms a stable oil film support under high-pressure conditions.
5. Elastomer Seals – Eliminating External Leakage
Elastomer seal design completely eliminates traditional gasket sealing methods, effectively preventing external leakage. Combined with “no-leak” hydraulic control adjustments, this significantly enhances long-term operational reliability.
6. Full Power Thru-Drive Capability
Full power thru-drive capability allows series mounting of additional hydraulic pumps or motors at the pump rear end, eliminating the need for additional power dividers and simplifying multi-pump system layouts.
Application Areas
Industrial Hydraulic Systems: Power units – medium-pressure hydraulic power for various industrial equipment
Injection Molding: Injection molding machines, extruders – precise controllable hydraulic power
Metal Forming: Presses, stamping equipment – medium-pressure variable flow supply
Water Jet Cutting: Water jet cutting equipment – stable high-pressure water source
Oil & Gas: Oil lift pumps, top drives – reliable hydraulic power in harsh environments
Material Handling: Conveyor drives, lifting equipment
Expert Maintenance Tips
1. Housing Priming Before First Start
Before starting a newly installed or overhauled PD045, fill the pump housing with clean hydraulic fluid through the case drain port. Never start the pump with an empty housing – this will cause instantaneous dry-running damage to critical friction pairs.
2. Fluid Cleanliness Control
PD series pumps require fluid cleanliness to ISO 4406 20/18/14 or better. Use high-precision return filters. Contamination is the leading cause of wear on the valve plate and cylinder block face.
3. Piping Connection and Bleeding
After installation, run the pump at low pressure and bleed slowly to ensure complete air removal from the housing and suction line. The suction line must be completely leak-free to prevent air ingress and cavitation damage.
4. Shaft Alignment Precision
Maintain shaft concentricity within allowable limits. Use standard flexible couplings to compensate for minor misalignment and prevent premature bearing failure.
5. Regular Inspection and Maintenance
Regularly inspect pump shaft seals and the sealing condition of all connecting lines. Follow the Parker P1/PD Series Service Manual (Bulletin HY28-2708-02/SVC/EN) for scheduled maintenance and servicing.

Expert Maintenance Tips
1. Housing Priming Before First Start
Before starting a newly installed or overhauled PD075, fill the pump housing with clean hydraulic fluid through the case drain port. Never start the pump with an empty housing – this will cause instantaneous dry-running damage to critical friction pairs.
2. Fluid Cleanliness Control
PD series pumps require fluid cleanliness to ISO 4406 20/18/14 or better. The 75 cc large-displacement pump is particularly sensitive to contamination – use high-precision return filters (β10≥75).
3. Suction Line Design
At 1,800 rpm, the PD075 delivers 135 L/min flow. Ensure sufficient suction line diameter (2″ piping minimum) to maintain inlet velocity below 1.2 m/s. Keep suction lines as short as possible with minimal bends to prevent excessive suction resistance.
4. Shaft Alignment Precision
SAE C flange pumps require higher mounting rigidity. Maintain shaft concentricity within allowable limits. Use standard flexible couplings to compensate for minor misalignment.
5. Thru-Drive Series Mounting Precautions
When using the thru-drive for series mounting of additional pumps, ensure the total torque load does not exceed the PD075 thru-drive rating. Use Parker-recommended couplings and mounting adapters.
