Eliminate Dry Run Failure
Replacing bearings, magnets, and containment shells can be very expensive. The damage can often be so severe that a complete replacement pump may be required.
A feature of the TSA-Plus is its patented Shaft Power Monitoring technology. The pump's working load is constantly monitored and compared to protection parameters. An abnormal condition, such as dry-running, will cause a drop in shaft power and the TSA_Plus will automatically shut the pump down - before damage occurs.
