PUMP SEAL FAILURE RELAY, 120V

SFP Series Information

  • Monitors Submersible Pump Seals and Leakage
  • Single or Dual Channel for Monitoring 1 or 2 Pumps
  • Three Adjustable Sensitivity Ranges
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, lowering 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 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.
  • Optional Fixed Sensitivity Setting Available
  • Optional Low‑Profile Adjustment Knob
  • Uses industry‑standard 8 & 11 pin octal sockets
