Twin VSD Pump Sets

              Twin Variable Speed Drive Pumps Sets

Communication and timing switching (alternate running function). The inverters can communicate with each other. The working pump can be switched by setting the time in order. Pumps can be set to start up alternatively or by running time to share the load of work equally.

Fault detection and automatically switching. Should one pump fail the secondary pump will resume the work load.

If one pump cannot keep up with the volume demand the second will start up keeping the pressure stable in the reticulation network.

Anti-freeze program setting to start up pumps according customer requirements.

Self-reset after the power failure or other reasons which cause the pumps stop running, the inverter records last running state. For example, when the power input again, the system will restore operation according to the final memory.

Dry run protection which shut down system when no water is detected.
