Pump Seal Failure Relays Indicate Possible Leaks

Macromatic features a line of pump seal failure relays that are designed to work with submersible pumps. They check the shaft seals for leaks to alert the user of a possible problem. Typically they are connected to an alarm to give immediate warning. These plug-in style relays all feature LEDs to show when a leak is found. Both single and dual channel relays are available for working with one or two pumps. Sensitivity is adjustable within three different ranges, with SPDT, DPDT, or SPNO output contacts. AC input voltages can be either 120V or 240V. These relays have an automatic reset once the problem is fixed.
