Viking Pump has introduced the Power Load Monitor for protecting any motor-driven pump and pump system from either overload or underload conditions created by over-pressure, cavitation, empty tank or other problems. Suitable for both new installations and for upgrading existing units, the new Power Load Monitor helps prevent downtime and reduce maintenance costs caused by pump and system problems. By monitoring both voltage and power, the Power Load Monitor measures the normal working load, then calculates and sets an automatic shutdown point for detected power changes. The load limit margin is adjustable to prevent unintentional stoppage.Viking Pump.
