Seal Leakage Relays monitor pumps using Resistance Sensing Leakage Detection to provide a warning of leaking seals. Select from single channel or dual channel configurations to monitor two pumps. Two sensitivity ranges are available to meet requirements.
SEAL LEAKAGE &
TEMPERATURE RELAYS
Seal Leakage Relays monitor the shaft seals of submersible pumps to protect against damage and premature failure. Combination Over Temperature & Seal Leakage Relays provide protection from both conditions. Everything needed for easy set-up, operation and troubleshooting is on top of the units: Bi-color LED status indication and low-profile adjustments.
Monitor and Protect Submersible Pumps From Damage
Models are available with plug-in enclosures (SFP and TCP Series) or Flange Mounted (SFF and TCF Series) for mounting on inner door with a back-mounted socket.
SEAL LEAKAGE RELAYS
OVER TEMPERATURE & SEAL LEAKAGE RELAYS
These single channel relays protect pumps against damage from both conditions. TCF-A models can be installed in place of existing Flygt MiniCas; TCF-E works with pumps using float-type sensors; TCF-F works with pumps using CLS or FLS sensors.

Frequently Asked Questions About Current Sensing Relays
Some submersible pumps have non-standard seal and temp sensors. Visit this link to help determine which product is best for your pump.
Macromatic maintains an extensive cross reference database. Follow the link here.
Macromatic relays specify the power consumed by the device as “burden” in units of VA. Look for the burden specification in the catalog page for the specific device you have. The unit of VA(volt-amps) is essentially the same as Watts(power), current draw can be calculated in Amps by taking the VA specification and dividing by the voltage control voltage you are using to power the device.
First consult pump documentation as some pumps have specific requirements. If none, dial the sensitivity to its highest level(highest resistance). If the relay gives no alarm you are done. If you receive a seal alarm, adjust the sensitivity back down until the alarm clears. Typical seal leak detection applications use sensitivity settings from 5K to 50K ohms. Lower values are less prone to nuisance alarms but are also less sensitive to the onset of seal leakage.
