Product Description: Parker PGP330 Hydraulic Gear Pumps
The Parker PGP330 gear pump is a high-performance, heavy-duty hydraulic solution engineered for demanding industrial and mobile applications. Renowned for its robust construction and versatility, this pump excels in environments requiring reliable power delivery, efficiency, and longevity. Designed with Parker's signature precision engineering, the PGP330 series is ideal for systems operating under extreme pressures and variable loads.
Key Features & Benefits
Robust Cast Iron Construction:
Built with a three-piece cast iron body, the PGP330 ensures exceptional durability and resistance to wear in harsh conditions
. Its low-friction bronze bushings enhance lubrication and reduce heat generation, extending service life even in abrasive or high-temperature environments.
High-Pressure Capability:
Delivers continuous operating pressures up to 241 bar (3,500 psi) and accommodates intermittent peak demands, making it suitable for heavy machinery, construction equipment, and material handling systems
Optimized Efficiency:
Features balanced side plates to minimize internal leakage and friction, improving volumetric efficiency and energy savings
The design ensures stable performance with both standard hydraulic oils and specialty fluids like water-glycol or phosphate esters
Flexible Configurations:
Available as single, multiple (up to 6 pumps), piggyback, or thru-drive units
Supports SAE, ISO, DIN, NPT, BSPP, and ODT port connections for seamless integration into diverse hydraulic circuits
Integrated Valve Options:
Optional integrated valves enhance functionality and reduce system complexity:
Relief valves for pressure control.
Load-sensing priority valves for optimized flow distribution.
Unloading valves for energy efficiency
Wide Operating Range:
Speed: Up to 3,000 RPM.
Fluid Temperature: -20°C to 80°C (-0°F to 180°F).
Viscosity: Compatible with fluids ranging from 50 to 7,500 SUS, ensuring adaptability to varying operational conditions
