Whale Watermaster IC Submersible Pump – EP1632

The Whale Watermaster IC controller and high-flow submersible pump is ideal to use to for a pressure based water system, as surge in battery voltage can cause the internal pressure switch in the socket to fluctuate. This can lead to pulsations in water flow. Similarly if the battery voltage drops, the pump may be unable to produce enough pressure to activate the pressure switch and the pump may run on continuously. Also if the external water container runs out, the pump will continue to run on, this drains the battery and may reduce the life of the pump. Until now the only solution has been to manually adjust the pressure switch. With the Watermaster IC this will reduce these problems and the need for pressure switch adjustment.
Innovative electronic control circuitry monitors the level of battery voltage and compensates for any surges or reductions in battery voltage that can occur. It also cleverly senses when the water container runs dry and switches the pump off.

*Whale Watermaster IC is compatible with a Whale Watermaster pressure switch socket and a Whale Watermaster High-Flow pump only
