4.8 Pump with sealing gas unit
To prevent the gear box from penetrating aggressive media, the sealing system uses sealing gas (see sealing
gas connection (S)).
The sealing gas unit is equipped with a safety valve (S
1
), sealing gas flow meter (S
5
), and a sealing gas valve
(S
6
).
Safety valve
(S
1
)
It protects from an incorrect operating pressure of the cooling water of > 0.3 bar.
Sealing gas flow meter
(S
5
)
It indicates the measured sealing gas consumption depending on the operating point
Sealing gas valve
(S
6
)
It controls the operating pressure
Maximum permissible operating pressure 0.2 bar
The gas ballast valve (S
2
) with vacuum-tight suction valve (S
3
) and silencer (S
4
) reduces the condensation
inside the pump at operating temperature.
NOTICE
Material damage!
The system can get leaky due to pressure increase and oil can escape from the gear
box.
Ø
Operation of the pump without safety valve is not allowed.
