Viking
Power Load Monitors
Design Features
The 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.
The M-10
monitors can be set to detect either an underload condition
(indicating dry running or cavitation) or an overload condition
(indicating overpressure* situations). The M-20 can detect
both underload and overload conditions. The monitors are
capable of handling both 50 and 60 Hz power, single or three
phase, on loads up to 999 HP.
*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.
