PUMP SEAL FAILURE RELAYS Single & Dual Channel SFP Series Plug-in SFP Series Pump Seal Failure Relays are designed to monitor the shaft seals of submersible pumps. A resistive-measuring probe is installed in the pump seal cavity. If the seal starts to leak, contaminating fluid enters the seal cavity. This lowers the resistance between the internal probe & the common connection. When the resistance drops below the user-adjustable sensitivity set-point of the relay, the output relay energizes & the LED turns Red ON. The relay output can be used to give an alarm indication of a leaking seal. These products will automatically reset when the fault condition clears. Three output configurations are offered: an 8 pin SPDT single channel relay & an 11 pin DPDT single channel relay to monitor a single pump, and an 8 pin dual Single Channel Dual Channel channel relay (with 2 SPNO contacts) to monitor two pumps. Probes are pulsed Monitors Submersible Pump with a DC voltage to prevent electroplating issues.
