**Application** In cases where a single vacuum pump is not suitable for a specific process due to insufficient pumping speed or ultimate vacuum level, the DYK series vacuum pump units are designed with 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, which provides high pumping speed at higher vacuum levels. These units come equipped with air cooling systems, water cooling systems, vacuum valves, ventilation valves, compensators, and vacuum gauges, ensuring efficient, reliable operation while consuming less power. They can be customized and mounted on base frames for immediate use or on trailers to meet user-specific requirements. The DYK series is widely used in vacuum metallurgy, drying, welding, chemical processing, laboratories, power stations, and other industrial vacuum applications, particularly 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. The powerful rotary vane backing pump ensures sufficient backing pressure, allowing diffusion pumps to achieve full pumping speed and ultimate vacuum. 3. The unit includes a vacuum valve at the inlet and a rough vacuum line (bypass), making it highly efficient for rapid evacuation cycles. 4. The high-vacuum pump unit offers excellent energy savings, high efficiency, reliability, and low power consumption. **Technical Specifications**
