Rotary Vane Vacuum Pump VRT Series

Product Overview

The VRT Series Rotary Vane Vacuum Pump features an oil-sealed, two-stage design for simple construction and high reliability, capable of rapidly reaching high vacuum levels. As a fundamental vacuum solution, it utilizes rotating canes for efficient gas evacuation, delivering low noise operation and high ultimate vacuum performance.
Features
  • Variable-frequency motor for precise speed control and high energy efficiency.
  • Ductile iron construction ensuring structural stability and consistent vacuum.
  • Built-in anti-backflow valve to prevent oil contamination after shutdown.
  • Pressure force lubrication with wear-resistant rotor for quiet high-pressure operation.
  • Transparent oil window for real-time oil level monitoring.
  • Nickel plating anti-corrosion process for pump body components greatly reduces the chance of pump jamming.
  • Advanced exhaust and gas ballast valve to prevent oil emulsification.
  • Standard oil mist filter for trapping vapors and extending service life.
