Pump Seal Failure Relays

AutomationDirect offers three types of monitor relays for motor control: Phase Monitoring Relays for phase loss protection Alternating Relays for motor load protection Pump Seal Failure Relays for seal failure detection Pump Seal Failure Relays are designed to monitor the shaft seals of submersible pumps. A resistive-measuring probe provided by the pump manufacturer is installed in the pump seal cavity. If the pump seal starts to leak, contaminating fluid enters the seal cavity, lowering the resistance between the internal probe and the common connection. When the resistance drops below the user-adjustable sensitivity setpoint of the relay, the output monitor relay energizes and the LED turns ON. PSFR series pump seal failure relays are designed to monitor the shaft seals of submersible pumps for leakage. Single or dual channel for monitoring one or two pumps User-adjustable sensitivity setpoint for the relay (4.7K, 20K, 47K and 100K) LED indication when the output relay energizes The relay output can be used to give an alarm indication of a leaking pump seal Automatic reset when the fault condition clears.
