PS Communicator and pumpMANAGER

Remote Communication Device and Cloud Management Service

The LORENTZ PS Communicator and pumpMANAGER service combine to offer customers a cost effective full management and monitoring system for their LORENTZ pump estate. This is attractive to commercial farms, industrial processes, government or NGO monitoring and anywhere that water is critical to people, livestock or crops.

The PS Communicator sends data from each pump across the cellular (mobile) data network to a secure central web server application called pumpMANAGER. The pumpMANAGER application can be accessed from any web connected device anywhere in the world making access to information and control of your solar pumps simple and convenient. As the connection is two way the pumps can be programmed, speed controlled or switched off, providing full remote control.

The pumpMANAGER application also monitors the status of your LORENTZ pumps systems and will alert you if there are any unexpected events.
