6.2.1

Connecting the media line

WARNING
Remove sealing plug
The suction connection (Pos.9) is protected against the ingress of dirt and foreign bodies for transport with a
sealing plug. This must be removed shortly before commissioning.
Dimensioning the suction line
The diameter of the suction line depends on the pump size and the line length.
There is an internal thread in the connection flange. Lines with a minimum diameter according to the follo-
wing table must be used.

Tab. 4 Cable lengths
Keep connections free of oil, grease, water and other contaminants.
The supply line must be installed mechanically stress-free using a flexible hose or rigid pipe.
Exhaust air
The exhaust air is discharged via the blow-off valve (pos. 4).
Some variants have an additional exhaust air connection on the connection strip instead of the blow-off val-
ve (same connection size as suction connection).
• The exhaust must be installed mechanically stress-free using a flexible hose or rigid pipe.
• It must be ensured that the exhaust air can flow out without major back pressure (see chapter 2.6).
• At high exhaust air temperatures, the exhaust air duct must be designed in such a way that it does not
pose any danger.
6.2.2

Adjust Valves

Adjusting the vacuum
The pump is equipped with a vacuum regulating valve, which can be used to set the vacuum required for
the application.
Depending on the size, this value is limited.
Information on this can be found in chapter 9.1.
