Vickers injection molding machine variable vane pump
Vickers Variable Vane Pump for Injection Molding Machines
As a core component in the hydraulic system of injection molding machines, the Vickers variable vane pump is engineered to deliver efficient, reliable, and precise hydraulic power transmission. Leveraging Vickers’ over 100 years of expertise in hydraulic solutions, this series of pumps is specifically optimized for the demanding operating conditions of injection molding processes, such as frequent pressure fluctuations, continuous operation, and strict energy efficiency requirements .
Core Features
- Hydraulic Balancing Structure: Adopting a pressure-balanced modular design and hydraulic balancing vane structure, the pump effectively reduces radial shaft and bearing loads, minimizing wear on internal components and extending service life. The diametrically opposed inlet and outlet chambers further enhance operational stability by reducing uneven wear .
- Low-Noise Operation: Equipped with a 12-vane system, the pump minimizes flow pulsations, resulting in extremely low noise levels (as low as 62 dB(A)). This feature creates a more comfortable working environment and meets the noise emission requirements of modern industrial production .
- Energy-Saving Variable Displacement Design: The pump adjusts the output flow automatically by changing the eccentricity between the stator and rotor according to the system’s pressure and flow demands. Compared with fixed-displacement pumps, it significantly reduces energy consumption during no-load or partial-load operation, achieving excellent energy-saving effects for injection molding machines .
- Easy Maintenance & Configuration Flexibility: Featuring an innovative intra-vane cartridge design, the pump allows for quick maintenance and cartridge replacement without removing the pump from its mounting, minimizing downtime. It offers a wide range of configurations, including single, double, and thru-drive options, as well as multiple displacement ranges and port orientations, adapting to different injection molding machine models and hydraulic system layouts .
