Product Description
HQI & HQB Series High-Performance Low-Noise Hydraulic Gear Pumps
Product Overview: The HQI and HQB Series represent the pinnacle of “High Precision” and “Silent Operation” in the industrial hydraulic sector. This range encompasses the complete spectrum from HQI2 and HQI3 internal gear pumps to the HQB external gear series. This featured range highlights core models: the precision HQI2-004RK04-11S122, the medium-displacement HQI2-016RK23-10S12, and the heavy-duty HQB 025RK23-10S100. Utilizing advanced pressure compensation designs, these pumps provide exceptional dynamic response and minimal pressure pulsation when paired with servo motors, serving as core components for modern energy-saving hydraulic systems.
Key Technical Advantages:
Ultimate Silent Design: Optimized internal gear geometry (for the HQI series) significantly reduces fluid pulsation and mechanical noise, making it ideal for indoor precision environments.
Superior Pressure Resilience: Rated for continuous working pressures up to 25 MPa (250 Bar), with peak capabilities ensuring long-term stability in injection molding and die-casting operations.
Servo System Optimization: Specifically engineered for servo-hydraulic drives, featuring ultra-low starting torque and excellent low-speed performance for precise flow and pressure control.
Peak Volumetric Efficiency: Equipped with automated axial and radial gap compensation mechanisms, maintaining efficiency above 95% across the entire pressure range and reducing oil heating.
Target Applications: Servo injection molding machines, CNC shearing/bending machines, forklift hydraulics, and laboratory precision power stations.
Detailed Models & Parameters:
Core Series: HQI (Internal Gear) & HQB (External Gear) Series.
