NETZSCH dry running protection for NEMOLAST® stators

    The dry running protection units (STP2A, STP2D) continually monitor the surface temperature of the stator during operation. Should the operating temperature rise over a predetermined set point due to an increase in friction caused by dry running, a signal is sent to the motor control unit and the pump shuts down. This prevents any damage to stator and rotor. The controller can be set for two different switch-off temperatures: the first set temperature would be for the normally pumped product, the second set temperature for a different substance temperature, for example during a cleaning process.
