Dry Running Protection for Pumps
Simple to install Maintenance-free Uses motor as sensor

RELIABLE AND MAINTENANCE-FREE
The March M10 protects all types of centrifugal pump against damage due to dry running and cavitation. When either situation occurs, shaft power is reduced, activating the M10 which then stops the pump motor. In this way, the danger of pump damage and the costly repairs caused by dry running and cavitation can be avoided.

CHOICE OF ALARM LEVEL
By pressing the Auto Set button under normal working load, the alarm level is calculated automatically on the basis of actual measured motor loading (Auto Set level).

MEASURES WITHOUT A SENSOR
The March M10:
uses the pump motor as a sensor
measures pump motor input power
calculates power loss using a unique algorithm
gives precise shaft power
The need for mechanical load protection, external sensors, and cabling is minimized so that installation is simplified 'and maintenance costs are reduced.

ADVANTAGES OF USING THE M10:
Increased pump life reduced spares requirement
Reduced unplanned service interruptions
Reduced production shortfall
