TSE Dry Run Protection
Product Announcement from SEEPEX Inc.
SEEPEX TSE Dry-Run Protection The seepex TSE protects against dry run damage, the most common cause of progressive cavity pump failure. Friction between rotor and stator resulting from an unexpected loss of lubricating liquid can destroy a stator, resulting in unexpected production shut downs and costly repairs. Intrinsically safe models are available for hazardous areas, as are models for 115 VAC, 230 VAC and 24 VDC control voltages. An adjustable set-point control unit (with isolated relay contacts) is integrated within the starter or VFD panel for the pump motor and is connected to the temperature sensor installed in the pump stator. The set-point temperature is adjustable. If the pump runs dry, the temperature rises due to increased friction between rotor and stator. Once the set point is reached, the TSE control unit can stop the pump drive and activate an alarm signal.
