Viking Power Load Monitors provide a simple, cost effective, state-of-the-art method to monitor pump and system problems and alarm or shut down the pump when a change of load is detected at the motor.  They are applicable to positive displacement or centrifugal pumps, as well as other types of motor-driven equipment.  They are especially useful for pumps which are susceptible to damage due to dry running, such as sealless magnetic drive pumps*.

Viking Power Load Monitors require NO special programming and NO external power supply.  They are small enough to fit into a typical motor starter enclosure and can be set in as little as 3 seconds!

*Note: The power load monitor should not be used as exclusive protection in case of sudden discharge line blockage on positive displacement pumps.  Other means of protection such as a pressure relief valve must be used in conjunction with the power load monitor to avoid pressure spikes in the system.
