Product Description
HG Series High-Pressure Silent Internal Gear Pumps
Product Overview: The HG Series is globally recognized as the “King of Silence” in the hydraulic industry. As high-performance internal gear pumps, this series is engineered for industrial applications demanding extreme operating pressures (Rated 31.5 MPa) and near-silent operation. This featured range includes core models: the micro HG0-8-01R-V, medium-displacement HG1-25-01R-VPC-36, and heavy-duty HG2-80-01R-VPC / HG2-125-01R-VPC. Its unique dual-gap compensation technology ensures near-perfect volumetric efficiency, especially under variable-speed servo-drive conditions.
Key Technical Advantages:
Ultra-Low Noise & Pulsation: The optimized internal gear profile ensures decibel levels significantly lower than external gear pumps. Minimal pressure ripples drastically extend the life of hydraulic lines, seals, and actuators.
Dual Gap Compensation: Equipped with automated axial and radial pressure compensation mechanisms. Even at extreme pressures of 31.5 MPa, it maintains a volumetric efficiency above 95%, effectively reducing oil overheating.
Perfect Partner for Servo Drives: Exceptional low-speed performance (stable high pressure even at 10-50 RPM) matches servo motor dynamics perfectly, enabling precise flow control and energy savings for injection molding machines.
100% Direct Replacement: Models like HG1-25 or HG2-125 adhere strictly to international flange and shaft standards. Suffixes like VPC and 01R guarantee seamless compatibility with original systems.
Target Applications: CNC injection molding machines, high-precision bending machines, ceramic presses, aerospace test rigs, and closed-loop hydraulic systems.
Detailed Models & Parameters:
Core Series: HG0, HG1, HG2 High Pressure Series.
Model Keywords: HG0-8-01R-V, HG1-25-01R-VPC-36, HG2-80-01R-VPC, HG2-125-01R-VPC, HG01/2.
Displacements: Covering precise specs from 8cc, 25cc, 80cc up to 125cc/rev.
Rated Pressure: 31.5 MPa (315 Bar); Peak pressure up to 35 MPa (5075 PSI).
Speed Range: Supports 300 – 3000 RPM (broader range achievable with servo integration).
