Description
Roots screw dry vacuum group system is a dry oil-free vacuum unit composed of ZJ type Roots pump as main pump and screw vacuum pump as fore stage pump. After the front-stage screw vacuum pump works, the starting of Roots pump is controlled by vacuum gauge and vacuum relay.
The Roots screw vacuum group is characterized by its exceptional attributes and versatile utility. This state-of-the-art system boasts an impressive vacuum degree, ensuring a highly efficient evacuation process across a broad working pressure spectrum. Notably, it stands out as an oil-free vacuum solution, making it an environmentally friendly and cost-effective option.
Designed with durability in mind, the system is fortified with anti-corrosion treatments, ensuring long-term reliability even in harsh industrial environments. Its remarkable pumping efficiency extends its suitability across an array of industries, including medicine, electronics, solar energy, metallurgy, and food processing.
In the pharmaceutical sector, this vacuum unit finds its niche in high vacuum distillation, vacuum evaporation, dehydration crystallization, and various critical processes. Furthermore, in the electric power industry, it excels in vacuum dipping and vacuum drying applications, demonstrating its adaptability and efficacy.
This vacuum system also emerges as the preferred choice for applications such as vacuum coating, vacuum smelting, vacuum heat treatment, vacuum filtration, and freeze-drying. Its versatility and precision make it an indispensable asset for achieving consistent and high-quality results in diverse industrial processes.
The main features advantages:
1. There is no oil in the pump cavity, no pollution to the pumped system, and clean high vacuum can be obtained.
2. No oil in the pump chamber, very easy to realize the recovery of solvents.
3. The pump chamber of Roots pump and screw pump are nickel-plated or coated with Hastelloy coating, which can pump water vapour, solvent gas and other corrosive media.
4. Because the main pump and the fore stage pump are oil-free dry vacuum pumps, there is no wastewater and waste oil discharge. No pollution to the environment.
