Product Description
We have different volume for VRD series vacuum pump, pls click for more details.
VRD series vacuum pump are designed and manufactured to meet the requirements of various scientific and industrial applications such as analytic instruments, laboratories and product line for refrigeration, electronics, light, semiconductor, etc.
How is the performance of VRD?
1. Automatic anti-suck back valve, protect your system from oil and oil steam when power suddenly goes off.
2. Internal forced oil cycling system, fully lubricates the pump and make the lifetime longer and vacuum better.
3. Adjustable gas ballast for different needs of steam emission.
4. High reliable integrated cylinder structure, suits production lines better.
5. Different voltage types for different countries and regions.
