Connection to vacuum system
■
Inlet of SC 5 D is NW 25 and outlet is NW 16.
■
Inlet of SC 15 D is NW 25 and outlet is NW 16.
■
Inlet of SC 30 D is NW 40 and outlet is NW 25.
■
Install an isolation valve between the vacuum chamber and the pump's
inlet to prevent the drawback of debris from the vacuum pump into the
vacuum chamber during start-up or shut-down.
■
We recommend the use of an automatic valve as isolation valve which
closes during power failurer to prevent the drawback of debris from in
side the pump into the vacuum chamber.
■
Install a purge valve between the isolation valve and the pump's inlet.
Opening this purge valve during operation removes dirt and water vapor
from the pump.
■
Use the clean connecting tubing between vacuum chamber and vacu
um pump. We recommend the use of flexible tubing between inlet of
pump and the vacuum chamber so that the pump's vibration is not
transmitted to the vacuum chamber.
■
When connecting an exhaust line to the outlet of the vacuum pump, we
recommend the following maximum straight length:
SC5D pump model 30 meters of NW 16 tubing
SC15D pump model 5 meters of NW 16 tubing
SC30D pump model 15 meters of NW 25 tubing
■
Make sure that the exhaust line is not clogged during operation.
■
Make sure that the pressure at the pump's outlet does not exceed
atmospheric pressure.
