Audited Supplier ZJT Roots vacuum pump
Compared with the traditional two-lobe Roots vacuum pump, there are below advantages:
1. Much higher efficiency, lower temperature, vibration and noise.
2. More stable and reliable, more convenient to use and maintain.
Other features:
1. Lower failure due to the rotors are fixed and no axial run-out.
2. High-precision transmission gear and precision rolling bearing are used, resulting in low noise and smooth operation.
3. The main shaft use special mechanical seal to ensure oil-free pump chamber.
7. Mechanical seal, oil seal, piston ring labyrinth seal and other types of seal can be used for end cover.
8. It is used in pump combinations together with rotary vane vacuum pump, reciprocating pump, liquid ring pump, dry screw pump and other types of backing pumps to meet various process requirements.
DVP dry screw vacuum pump
A special variable pitch design, which is called "3rd generation design", can greatly reduce the gas discharge temperature than traditional gradual changing variable pitch design and increase the reliability and operation life. The dry screw vacuum pump is a suitable replacement for liquid ring vacuum pumps and has higher energy efficient, lower waste of water and more friendly to our environment. It would be a trend to use more and more dry screw vacuum pumps other than the liquid ring vacuum pump.
The benefit of dry screw vacuum pump compared to liquid ring vacuum pump:
