Pumps in petrochemical enterprises require uninterrupted switching. The bearing housing of standby pumps shall maintain the same cleanliness as operating pumps, so standby pumps need continuous protection from the oil mist lubrication system.

 

However, standby pumps consume far less oil mist than operational pumps. Unregulated oil mist flow will cause severe leakage at standby pump shoulders and lead to environmental pollution. The installation of flow controllers ensures proper lubrication for standby pumps, enables seamless switching between active and standby pumps, reduces oil mist leakage and cuts environmental contamination.

The flow controller has three working modes: Operation, Maintenance, Off
