## 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.

Monitors Submersible Pump Seals for Leakage 

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 channel relay (with 2 SPNO contacts) to monitor two pumps.  Probes are pulsed with a DC voltage to prevent electroplating issues.
