Product features:
1. Integral cylinder structure
The VRD series products adopt an integral cylinder body structure, which ensures the accuracy of the cylinder body and the influence of deformation on the vacuum pump structurally. At the same time, the top tangent point arc design is adopted to ensure the ultimate vacuum stability of the product.
2. Built in oil pump circulation forced oil inlet system
The VRD series products adopt a built-in oil pump circulation forced oil inlet system to provide forced lubrication to the pump chamber, so they can work effectively for a long time at an inlet pressure of atmospheric pressure.
3. Structure of automatic anti backflow oil valve
The VRD series products adopt an automatic anti backflow valve structure, which can automatically cut off the pumped system when the pump stops, ensuring the vacuum of the system and preventing contamination.
4. Adjustable gas town design
The VRD series products are equipped with adjustable gas dampers to ensure strong water vapor resistance and effectively eliminate condensable gases.
