Product Description
NBZ Series Low-Noise High-Pressure Internal Gear Pumps
Product Overview: The NBZ Series represents a premium internal gear pump solution engineered for industrial environments requiring extreme silence and high-pressure stability. This comprehensive range spans from the compact NBZ2 to the high-capacity NBZ5, featuring core models such as NBZ2-G10F, NBZ4-G50F, and NBZ5-G160F. Utilizing a unique internal gearing architecture and pressure-compensated design, the NBZ series delivers near-pulsation-free flow output even at peak pressures. It is the premier power choice for CNC machine tools, hydraulic elevators, shearing/bending machinery, and auxiliary systems for injection molding.
Key Technical Advantages:
Ultra-Quiet Operation: The internal gear principle drastically reduces impact and vibration during meshing, resulting in decibel levels significantly lower than traditional pumps for a better workspace.
Elite High-Pressure Durability: Constructed with high-strength materials, these pumps provide stable rated pressures ideal for long-duration industrial cycles.
Smooth, Pulsation-Free Flow: Optimized gear profiles ensure minimal flow and pressure ripples, enhancing the movement precision of hydraulic actuators like precision cylinders.
Comprehensive Displacement Range: From 10 cm³/rev (G10) to 160 cm³/rev (G160), providing precise scaling to meet the power demands of various-sized hydraulic stations.
Engineered for Longevity: Internal bearings and seals are optimized for continuous industrial duty, offering exceptional fatigue resistance and low maintenance costs.
