• Guardian™ VFD - PC Pump Controller

    The innovative design of our Guardian PC Pump Controller increases productivity and extends the life of new installations, while also providing upgrades to existing installation. By deploying our Guardian PC Pump Controller, operators greatly reduce maintenance and running cost while simultaneously providing optimum pump performance. Our Guardian PC Pump Controller comes automatically integrated with each Guardian VFD and no additional external hardware or interfaces are required, except for an inexpensive arm position. Our VFD connects to a standard A/C motor and provides maximum well production and lowering operational cost.
