**Application**
In cases where a single vacuum pump may not be suitable for certain processes due to insufficient pumping speed or ultimate vacuum level, the DYK series vacuum pump units combine a Roots pump as a booster and a rotary vane pump as a backing pump. The exhaust from the Roots pump is connected to the suction side of the backing pump, providing high pumping speed at higher vacuum levels. These units are equipped with air cooling systems, water cooling systems, vacuum valves, ventilation valves, compensators, and vacuum meters, making them highly efficient, reliable, and energy-saving. They can also be designed and mounted on base frames for immediate use, or on trailers to meet specific user requirements. The DYK series is widely used in vacuum metallurgy, vacuum drying, welding, chemical processing, laboratories, power stations, and other industrial vacuum applications, especially for vacuum transformers and other electrical equipment.
**Features**
1. The Roots pump automatically starts with the backing pump via an electrical-contact vacuum meter.
2. Powerful rotary vane pumps provide necessary backing pressure, allowing diffusion pumps to achieve full pumping speed and ultimate vacuum.
3. The system includes a vacuum valve at the inlet and a rough vacuum line (bypass), enhancing efficiency during rapid evacuation cycles.
4. The high-vacuum pump unit offers excellent energy savings, high efficiency, reliability, and low power consumption.
