Product Description
EIPH Series High-Performance Industrial Internal Gear Pumps
Product Overview: The EIPH Series represents the peak of power for modern precision hydraulic systems, specifically engineered for high-pressure, low-noise, and servo-driven applications. This featured range includes the entire core lineup: EIPH2-005-RK03-1X, EIPH3, EIPH5, and the high-capacity EIPH6. Utilizing unique radial and axial gap compensation, these pumps deliver extremely smooth, pulsation-free hydraulic power even under continuous high-pressure conditions (up to 31.5 MPa), making them the ideal heart for energy-saving servo hydraulic stations and precision machine tools.
Key Technical Advantages:
100% Plug-and-Play Replacement: Strictly adheres to international standard OEM specifications. Model codes such as RK03-1X guarantee that mounting flanges (SAE or standard pilots), shaft ends (keyed/splined), and port configurations are 100% compatible for a seamless installation.
Servo Optimization: Purpose-built for frequent speed variation and pressure-holding cycles of servo motors. With high starting torque efficiency and minimal internal leakage, it is the premier choice for energy-efficient servo systems.
Ultra-Quiet & Low Pulsation: The internal meshing characteristic ensures decibel levels far lower than external pumps. Minimal pressure ripples significantly reduce system vibration, protecting downstream precision control valves.
Superior Pressure Resilience: Rated for a continuous operating pressure of 31.5 MPa (315 Bar) with peaks reaching 35 MPa, maintaining exceptional volumetric efficiency even under extreme load surges.
Extreme Durability: Reinforced cast iron bodies combined with precision-ground gear sets offer superior fatigue resistance and contaminant tolerance, significantly extending operational lifespan in heavy-duty cycles.
