NACHI FUJIKOSHI PVD-1B-32 & PVD-00B-15 Technical Specifications & Applications
PVD-1B-32 Core Parameters & Applications
• Technical Specifications
• Displacement: 32 cm³/rev (typical), supports multi-stage displacement adjustment (e.g., P1/P2-16 cm³/rev, P3-10.5 cm³/rev).
• Pressure: Maximum operating pressure 21–24 MPa (some models up to 240 bar), suitable for high-load conditions.
• Rotational Speed: Rated 2300 r/min, maximum 2500 r/min, ensuring efficient power output.
• Structure: Semi-cylindrical swashplate design reduces flow loss; slipper, swashplate, and port plate adopt noise-reduction structures, with noise levels ≤75 dB.
• Control: Standard constant power control, optional load-sensing valve or electro-hydraulic proportional control valve for precise flow regulation.
• Applications
• Primary use in 3–6-ton mini excavators (e.g., Caterpillar 305, Hitachi 200 Electronic Injection), providing main pump power; compatible with 2.5–3-ton mini excavators, drilling rigs, and loaders.
• Industrial: Machine tools, metallurgical equipment, injection molding machines for hydraulic drives requiring high precision and low energy consumption.
• Performance Features
• Energy Efficiency: Optimized flow path design reduces power loss by 15–20%; constant horsepower control maximizes engine power utilization.
• Durability: High-quality materials and advanced manufacturing processes ensure reliability in harsh environments (e.g., high temperature, dust), extending lifespan by over 30%.
• Compact Design: Small size and lightweight facilitate installation in confined spaces (e.g., excavator engine compartments).
PVD-00B-15 Core Parameters & Applications
• Technical Specifications
• Displacement: 15 cm³/rev (typical), suitable for light-load scenarios; some models support dual-pump structures (e.g., IPH-46B-32-80-11).
• Pressure: Maximum operating pressure 24.5 MPa, meeting needs of small-to-medium equipment.
• Rotational Speed: Rated 2800 r/min, compatible with high-speed operations.
• Structure: Variable axial piston pump design supports flow adjustment; internal drainage structure eliminates need for external drainage piping.
• Applications
• Primary use in 1.5–2.5-ton micro excavators (e.g., Kubota U15, Caterpillar 301.8) as main or auxiliary pumps.
• Agricultural Machinery: Tractors and harvesters' hydraulic systems; construction equipment: small loaders and forklifts.
• Industrial: Light machine tools and automation equipment for hydraulic drives.
• Performance Features
• Low Noise & High Efficiency: Corrected cycloidal + short-tooth internal gearing design reduces noise to ≤70 dB; optimized flow path enhances efficiency.
• Flexible Control: Supports pressure compensation and dual-pressure/dual-flow control for multi-scenario adaptability.
• Easy Maintenance: Modular design simplifies replacement of wear parts; standard constant power control improves energy efficiency.
Comparison & Selection Recommendations
• Key Differences
• PVD-1B-32: Larger displacement, higher pressure, ideal for medium-to-heavy equipment.
• PVD-00B-15: Smaller displacement, lower pressure, suited for lightweight equipment. Both support customizable controls (e.g., electro-hydraulic proportional, load sensing), but PVD-1B-32 offers a broader power range.
• Selection Guidelines
• Choose models based on equipment tonnage, load conditions, and space constraints; prioritize OEM-compatible or compatible models (e.g., Caterpillar, Hitachi, Komatsu).
• Refer to NACHI official documentation for parameter matching (e.g., displacement, pressure, speed).
