Prevents water hammering, bursting water pipes, or blowing off sprinkler heads.End of Pump Curve detects breaks and leakageThe feature detects breaks and leakage. End of curve triggers an alarm, shuts off the pump, or performs another user defined action.Dry Pump Protection lowers maintenance costs The VLT® AQUA Drive constantly evaluates the condition of the pump, based on internal frequency/power measurements.Standard cascade controllerThe in-built cascade controller controls up to three pumps with fixed lead pump. Motor AlternationThis built-in logic controls alternation between two pumps in duty/stand-by applications. Motion of the stand-by pump prevents sticking of the pump. An internal timer assures equal usage of the pumps.Flow compensationThe flow compensation feature reduces the pressure set point according to the flow - which saves energy. Initial/Final RampThe initial ramp provides fast acceleration of pumps to minimum speed, from where the normal ramp takes over. This prevents damage on thrust and bearings. Sensor less Pressure or Flow Control SafetyThe VLT® AQUA Drive can optionally be delivered with the safe stop functionality suitable for category 3 installations according to EN 954-1. This feature prevents the drive from starting unintended.AccessoriesA wide selection of accessories is available for the VLT® AQUA Drive to suit your needs.
