Description

The innovative design of our Guardian™ PC Pump Controller and Rod Pump Controller increases productivity and extends the life of new installations while also providing upgrades to existing installations. By deploying our Guardian PC Pump Controller, operators greatly reduce maintenance and running costs while providing optimum pump performance. Our Guardian PC Pump Controller and Rod Pump Controller come 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 lower operational cost.
