Product details

Product Overview

• Model: PD100

• Type: Variable Displacement Piston Pump

• Application Fields: Widely used in construction machinery, hydraulic steering systems, petrochemical, metallurgy, power generation, water treatment, aerospace, wastewater treatment, solid waste management, mining, dredging, cement industry, concrete pumping, shipping, and other related sectors.

Product Features

1. High-Pressure Output:

• Operating pressure up to10,000 psi (700 bar)or higher, meeting demanding high-pressure applications.

2. Easy Flow Adjustment:

• Enables stepless flow regulation by altering the swashplate angle or piston stroke.

3. High Volumetric Efficiency:

• Piston reciprocation in the pump chamber generates pressure differentials for fluid delivery, achieving volumetric efficiency of approximately95%.

4. Compact Structure:

• Space-saving design for straightforward installation and maintenance.

5. Enhanced Durability:

• Core components include piston-cylinder pairs, slipper assemblies, and port plates, featuring dual-metal plate and steel friction pair designs for extended service life.

6. Multiple Controller Options:

• Offers various displacement control methods for user-specific adjustments. Modular compensators ensure rapid response and stable operation.

7. Low-Noise Design:

• Incorporates corrugated chamber noise reduction technology to minimize operational noise, suitable for noise-sensitive environments.

Technical Specifications (Parker PD Series Example)
