Parker Axial Piston Pumps for Marine Main Engines

Parker axial piston pumps specifically designed for marine main engines are core components in marine hydraulic systems, renowned for their high reliability, robust performance, and excellent adaptability to harsh marine environments. These pumps are engineered to meet the rigorous operational demands of marine main engines, providing stable and efficient hydraulic power for critical marine applications such as propulsion systems, steering mechanisms, and auxiliary equipment drive.

Key Product Series & Technical Specifications

Parker offers a range of axial piston pump series tailored for marine main engine applications, with the PV Series and PVplus Series being the most widely adopted. Their technical specifications are optimized to match the power requirements and operating conditions of marine main engines:

• Displacement Range: 16 – 360 cc/rev (for PVplus Series), covering a wide spectrum of flow rate demands for different marine main engine sizes.
• Operating Pressure: Continuous operating pressure up to 350 bar; intermittent operating pressure up to 420 bar, ensuring sufficient power output for heavy-duty marine operations.
• Speed Rating: Maximum operating speed up to 3000 rpm (PVplus Series), compatible with the rotational speed range of most marine main engines.
• Fluid Compatibility: Suitable for standard hydraulic fluids, water glycol, biodegradable fluids, and fire-resistant fluids, adapting to various marine hydraulic system configurations.
• Temperature Range: Operating fluid temperature from -40°C to 115°C, capable of withstanding extreme temperature fluctuations in marine environments.

Core Features & Advantages

• High Power Density: Compact design with high operating pressure and displacement, enabling efficient power transmission in the limited installation space of marine engine rooms.
• Low Noise & Vibration: Equipped with integrated pre-compression volume, which effectively reduces pulsation and noise levels, improving the working environment of the engine room and reducing overall ship vibration.
• Fast Response & Precise Control: Advanced swashplate design and highly dynamic control systems ensure rapid response to load changes, enabling precise regulation of hydraulic power for marine main engine auxiliary systems such as fuel injection and valve control.
• Corrosion & Wear Resistance: Key components (e.g., fluid end manifolds, plungers) are made of high-strength titanium, cast iron, or corrosion-resistant ceramics, providing excellent resistance to seawater corrosion and wear, extending service life in harsh marine conditions.
• Easy Maintenance & High Reliability: Modular design and cartridge seal structure simplify maintenance procedures; no packing gland adjustment is required, reducing maintenance time and costs. Oversized crankshaft bearings enhance bearing life, ensuring long-term stable operation of the pump under continuous marine service conditions.
• Thru-Drive Capability: Supports 100% nominal torque thru-drive, facilitating multi-pump combination configurations and improving the integration and flexibility of the marine hydraulic system.

Marine Main Engine Application Scenarios

Parker axial piston pumps are widely used in hydraulic systems associated with marine main engines, including but not limited to:

• Propulsion system hydraulic control (e.g., main engine clutch and gearbox actuation).
• Steering gear hydraulic power supply, ensuring precise and reliable ship steering.
• Auxiliary equipment drive (e.g., marine lifts, hoists, winches, and cranes) powered by the main engine hydraulic system.
• Marine diesel engine fuel injection system control and valve actuation mechanisms.
