3.7 Connect the DP180 to your vacuum system
WARNING
Do not operate the DP180 with the exhaust-pipeline blocked. If the exhaust-pipeline is
blocked, the DP180 can generate exhaust-pipeline pressures up to 7 bar.
When you connect the DP180 to your vacuum system, take note of the following:
•
To get the best pumping speed, ensure that the pipeline which connects the vacuum system
to the DP180 inlet is as short as possible and has an internal diameter not less than that of the
DP180 inlet port.
•
Incorporate a flexible connection in the pipeline to reduce vibration and stress in the system
pipelines.
•
On very dusty applications, use an inlet-filter to minimise damage to the DP180.
•
You must be able to isolate the pump-inlet from the atmosphere and from your vacuum
system if you have pumped or produced corrosive chemicals.
• Adequately support vacuum pipelines to stop the transmission of stress to the
coupling-joints.
Use the following procedure to connect the DP180 inlet-flange to your vacuum system.
1. Remove the four cap-head bolts, nuts and washers, then remove the blanking-plate from the
pump-inlet.
2. Retain the nuts, bolts and washers for future use.
3. Use the Co-Seal supplied in the fitting-kit to connect the pump inlet-flange to your vacuum
system. Use the bolts provided in the general fitting-kit or the bolts removed in Step 1 to
secure the connection.
