Product Advantages
Core Positioning
Heavy-duty high-pressure internal gear pump built for large-scale hydraulic systems requiring high flow rates and extreme pressure resistance. Engineered to power heavy machinery and industrial equipment with demanding fluid delivery needs.
Key High-Flow & Power Traits
Displacements range from 81.4–162.8 ml/r, delivering nominal flow rates of 120.6–241.3 l/min (at n=1500 r/min) and a maximum permissible flow of 241.3 l/min. Weighs 43.5–52 kg, with a rugged build capable of withstanding heavy-duty operating conditions.
Extreme Pressure Performance
Boasts a maximum operating pressure of 350 bar (intermittent) for smaller specifications (080–125) and 260 bar for larger models (160), with continuous operation at 315 bar (HLP hydraulic oil). The axial and radial pressure compensation system ensures high volumetric efficiency even at maximum flow and pressure.
Structural & Installation Robustness
Features SAE-C-2 threaded flange (socket diameter 152.4mm) for secure subplate mounting, compatible with ISO 3019-1. Port sizes range from Φ32 (P) to Φ76 (S), with spline shaft options (Φ51–Φ76) designed for high-torque drives. Requires 4 M6 x 40 fixing screws (tightening torque 12.5–15.5 Nm) and fits subplates G66/01 (G3/8) to G534/01 (G3/4).
Environmental & Fluid Compatibility
Operates in ambient temperatures of -20 to +60 °C, with hydraulic fluid temperatures of -10 to +80 °C (HLP mineral oil) and -10 to +50 °C (special oils). Compatible with HLP, HEES, HFC, and HFD-U hydraulic oils, supporting viscosities of 10–300 mm²/s (10–100 mm²/s recommended for 3000 r/min).
Unique Application Fit
Designed for large hydraulic presses, heavy-duty material handling equipment, mining machinery auxiliaries, and high-flow hydraulic power units. Perfect for energy-intensive industrial processes such as metal forming, large-scale die-casting, and heavy conveyor systems.
Durability & Reliability
Constructed with reinforced high-strength cast iron housing to withstand high pressure and mechanical stress. The hydrodynamic lubricated radial sliding bearings and hydrostatically mounted internal gear ring ensure minimal wear, even in continuous high-load operations. Insensitive to oil contamination (ISO 4406 Class 20/18/15), extending service life in harsh environments.
Operational Stability
Features a long meshing involute tooth profile that minimizes flow and pressure pulsation, reducing system vibration and noise. The crescent plate gap adjustment (via plastic rod) maintains optimal sealing, ensuring consistent performance across the entire speed range (200–3000 r/min).
