Groco ETM All Voltage Timer

Groco ETM Timer All Voltages

Timer for all DC voltages, 12v, 24v, and 32v.

The Groco ETM is designed for use as dry-tank protection for pressure pumps, and is standard equipment on GROCO Paragon Junior (Models PJR, PJR-A and 401-0004), WSC Series and WSG Series water pressure systems. ETM will stop the connected motor if it runs non-stop for more than 10-minutes (previously 6-minutes).

If the pump is properly matched to vessel size and water usage habits, it will by building up system pressure and shutting off, even if you are drawing water continuously. For example, Paragon Junior delivers up to 7 GPM to the system, so its output will exceed the 2 to 4 GPM that is normally drawn from a single faucet or shower. PJR will build pressure and shut off before the timer times out. The timer is reset each time the pump reaches pressure and shuts off.
