Predictive maintenance improves pump diagnostics

| By Chemical Engineering


SafeGuard (photo) is a predictive maintenance solution featuring wireless access and proactive alerts for all types of centrifugal pumps. SafeGuard allows both the pump and the motor to be remotely monitored at all times with continuous cloud connectivity. If an issue occurs, a proactive alert is automatically generated, which includes clear actionable guidance that can be easily followed by maintenance personnel to resolve the root cause of the issue. Four battery-powered sensors are included in the SafeGuard system, as well as a node/sensor reader. All four sensors work in unison to predict the full health of both the pump and the motor. This allows for a complete diagnostic analysis that reads the tri-axial vibration, temperature and electromagnetic values for the pump and motor. With these capabilities, SafeGuard is able to detect more than 20 failure modes. — Griswold, part of PSG, a Dover Company, Grand Terrace, Calif.
