Product Advantages
Core Positioning
Versatile high-pressure internal gear pump engineered for medium-flow industrial hydraulic systems, balancing power, adaptability, and compactness. Suitable for a wide range of equipment requiring consistent medium-volume fluid delivery with high-pressure capability.
Key Flow & Power Traits
Displacements span 25.3–63.7 ml/r, with nominal flow rates of 37.5–94.4 l/min (at n=1500 r/min) and a maximum permissible flow of 94.4 l/min. Weighs 14.5–18.5 kg, offering a mid-range size that fits most standard hydraulic setups without sacrificing performance.
High-Pressure Reliability
Supports a maximum operating pressure of 350 bar (intermittent) and 315 bar (continuous for HLP hydraulic oil), with special hydraulic oils rated at 245 bar. The gap compensation design ensures high volumetric efficiency across the entire flow range, even under fluctuating pressure conditions.
Structural & Installation Flexibility
Features SAE-B-2 flanged socket (socket diameter 101.6mm) for subplate mounting, compatible with ISO 3019-1. Port sizes range from Φ18 (P) to Φ32 (S), with spline shaft options (Φ32) adhering to ANSI B92.1 standards. Requires 4 M5 x 50 fixing screws (tightening torque 7–8.9 Nm) and fits subplates G341/01 (G1/4) to G502/01 (G1/2).
Environmental & Fluid Adaptability
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 multiple hydraulic fluids, including HLP, HEES, HFC, and HFD-U, supporting viscosities of 10–300 mm²/s (10–100 mm²/s recommended for 3000 r/min).
Unique Application Fit
Ideal for medium-sized plastic molding machines, hydraulic presses, die-casting equipment, and material handling vehicles. Excels in servo frequency drive systems and industrial automation setups, where medium flow rates and stable pressure output are essential for process consistency.
Durability & Low Noise
Constructed with high-strength cast iron and a unique internal silencing design, achieving ultra-low noise levels (tested per DIN45635). Insensitive to oil contamination, with a robust sliding bearing and crescent plate structure that resists wear and extends service life.
Operational Stability
The floating spline coupling structure (for combination pumps) enables self-centering, ensuring stable operation and low vibration. Extremely low flow and pressure pulsation maintain consistent performance, even during long continuous runs.
