Product Name:
VRD-48 Double Rotary Vane Vacuum Pump

A Rotary Vane Vacuum Pump has the eccentric mounted rotor tangent to the fixed surface of the stator. Two (or more) rotary vanes slide in the rotor slot (usually radially) and contact the inner wall of the stator, dividing the pump chamber into several variable volumes.

Advantages:

1.Excellent performance, integral cylinder structure, higher accuracy, and proven rotary vane technology make the performance more stable and ensure that the system has a higher possibility;

2.DC brushless motor, low energy consumption, cost saving, small size, light weight, easy to install;

3.Low noise, quiet operation without disturbing work;

4.Forced lubrication, built-in gear pump and oil supply mechanism with constant pressure for forced oil supply, stable and reliable operation under high suction pressure;

5.Gas ballast to meet the customer's vacuum requirements and water vapor processing capacity;

6.Fluorine rubber seals improve corrosion resistance and solve the problem of oil leakage;

7.Double anti oil return structure and automatic anti oil return valve can more reliably protect your vacuum system from oil pollution after shutdown;

8.High quality oil mist filter can effectively filter oil mist and protect the environment.
