Connecting the EBARA oil free roughing pump
The oil-free roughing pump option involving the EBARA pump uses the EBARA SA-30.
For proper ventilation, the following minimum clearances must apply:
Figure 1: EBARA oil-free roughing pump clearances.
Required materials
- Chemical-resistant, powder-free gloves
- 7-mm nut driver
- Sharp knife
The following items are included in the installation kit:
- NW25 center rings
- NW25 clamps
- NW40 center rings
- NW40 clamps
- NW40 elbow
- NW40 tee piece
- NW40 to NW16 reducer
- NW40 to NW25 reducer
- 12-mm clear PVC exhaust tubing
- PVC hose clamps
- Vacuum hose
To connect the oil-free roughing pump
WARNING: To avoid personal contamination with biologically hazardous or toxic compounds, wear clean, chemical-resistant, powder-free gloves when performing this procedure.
WARNING: To avoid injury, do not lift the pump. To move the pump, use its wheels.
- Connect the roughing pump's vacuum hoses according to the figures below.
Note: To avoid gas leaks, use the sharp knife to cut the PVC exhaust tubing squarely.
Recommendation: Use elbow connectors for fitting the vacuum and exhaust tubing to the pump to reduce the height so it fits under a workbench.
Requirement: The gas ballast valve must be left open. Loosen the nut on the gas ballast port, but do not remove it.
