Structure
Structure: The DP type screw vacuum pump serves as the fore pump, and the ZJ type vacuum pump is the main pump. Through various instruments, valves, and an electrical control system, the unit achieves automatic start/stop, overload protection, overheat protection, and automatic control.
Applications
Applications: This system is suitable for long-term operation within a pressure range from atmospheric pressure to several tens of pascals. It can replace vacuum systems that use water ring pumps, reciprocating pumps, or water jet pumps as fore pumps, solving issues related to pollution and recovery.
The JZJDP Roots/Screw Dry Vacuum Pumping System is a growing trend in the pharmaceutical and chemical industries.
Advantages and Features
- Complete specifications and a wide range of applications.
- Clean and oil-free, capable of recovering various gas media.
- Excellent dust and liquid handling capabilities.
