Viking® Rotary Gear Flow Dividers Get More From Your Source... Reduce downtime and maintenance costs Protect pumps and other motor driven equipment Lower operation costs Simple to set ¡ ¡ ¡ ¡ Empty tanks, cavitation, and unintended line restrictions can quickly damage or destroy your pumps, costing you time, money, and possible loss of product. The installation of the Power Load Monitor can provide a simple, cost effective, state of the art way to monitor and shut down your pump when a change in motor power load is detected. Power Load Monitors are well suited for systems using positive displacement, centrifugal, or sealless magnetic drive pumps and other types of motor driven equipment. Power Load Monitors will protect the pump and system from damage caused by dry running or cavitation as indicated by an underload condition. Or it can be set to detect overpressure situations* as indicated by an overload condition. Viking offers two Power Load Monitors. The M10 Power Load Monitor senses either an over power or under power event, and automatically stops the motor. The M20 Power Load Monitor provides protection for both overload and underload situations plus triggering a pre-alarm and/or shut down sequence. The monitors are capable of handling both 50 and 60 hertz power, single or three phase, on loads up to 999 hp. With a simple press of a button, the Power Load Monitors can be set to detect abnormal over-load or under-load conditions and apply protection parameters. The unit measures the normal working load, then calculates and sets an automatic shutdown point for detected power changes. Protection margins can be fine-tuned to prevent unintentional stoppage. * 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.
