Monitoring with MAS
The pump is designed for use with the Flygt MAS monitoring system. The parameters tracked are chosen
by the customer and can include the following:
• Temperature (main and support bearings, stator windings)
• Vibration
• Leakage (in stator housing, junction box, and water into oil chamber)
• Power monitoring
Table 41: Parameters monitored
