For our DKY-1200:
Dyk-1200 transformer vacuum pumps are suitable for vacuum pumping operation of electrical equipment of distribution industry, power supply bureau, power plant and transformer manufacturer. It can reach 10 Pa working vacuum and 1 Pa Limited vacuum. The system is not suitable for pumping toxic gases, explosive gases, high oxygen gases, high water content gases and gases that react with pump oil or corrode ferrous metals.
1) Roots pumps start up and run automatically through the front pump with an electric contact vacuum gauge.
2) Powerful rotary vane front stage pump produces the necessary back pressure, so that the diffusion pump can always reach its full pumping speed and limit vacuum.
3) There are vacuum valves and thick vacuum lines (bypass) at the inlet of the pumping unit. This makes it particularly effective for rapid evacuation cycles.
4) High vacuum pump device has excellent energy-saving effect, high efficiency, reliability and low power consumption.
