Product Advantages
Core Positioning
Compact high-pressure internal gear pump designed exclusively for small-scale hydraulic setups, prioritizing space-saving design and efficient low-flow output. Ideal for equipment where installation space is limited but high-pressure performance is non-negotiable.
Key Size & Flow Traits
Weighs just 4.6–6 kg with a compact footprint, featuring displacements ranging from 8.2 to 25.0 ml/r. Delivers low nominal flow rates of 12.2–37.1 l/min (at n=1500 r/min), perfectly matching the demand for precise, low-volume fluid delivery in miniaturized systems.
High-Pressure Performance
Boasts a maximum operating pressure of 350 bar (intermittent) and 315 bar (continuous for HLP hydraulic oil), ensuring reliable performance in pressure-sensitive applications. Maintains high volumetric efficiency even at low rotational speeds (minimum 600 r/min) and low viscosity conditions via axial and radial pressure compensation.
Structural & Installation Advantages
Adopts SAE-A-2 threaded flange (socket diameter 82.55mm) for subplate mounting, compatible with ISO 3019-1 standards. Port sizes range from Φ13 (P) to Φ26 (S), with flat key or spline shaft options (Φ20–Φ26) for flexible drive connection. Requires 4 fixing screws (M5 x 50) with a tightening torque of 7–8.9 Nm, simplifying installation in tight spaces.
Environmental & Fluid Compatibility
Operates in ambient temperatures of -20 to +60 °C, with hydraulic fluid temperatures ranging from -10 to +80 °C (HLP mineral oil). Compatible with HLP mineral oil (DIN 51524 Part 2), HEES hydraulic oil (DIN ISO 15380), and HFC water-based solutions, supporting a viscosity range of 10–300 mm²/s.
Unique Application Fit
Tailored for plastic molding machines, small electric forklifts, shoe-making equipment, and precision die-casting tools. Excels in energy-efficient servo frequency drive systems, where low flow pulsation and ultra-low noise (via internal silencing design) are critical.
Durability & Maintenance
Insensitive to oil contamination (ISO 4406 Class 20/18/15), ensuring a long service life. Features a fixed displacement clearance compensation design with sliding bearings and crescent plates, reducing wear and minimizing maintenance needs.
Control & Stability
Delivers extremely low flow and pressure pulsation, even at low speeds, thanks to the involute tooth profile with long meshing length. The axial and radial pressure compensation system maintains stable output, preventing pressure drops in continuous low-flow operations.
