Littelfuse/SymCom pump controllers are innovative products for controlling a single pump or multiple pumps. Some models can be used to detect pump seal leaks and motor overheating on submersible pumps. Other models can be used as a five-channel pump controller or five-channel switch to support all popular industry standard multi-pump configurations. In submersible pump applications, early indication of seal failure is critical to allow maintenance of the pump before additional damage occurs. SymCom seal leak and leak/temp relays provide protection against seal leaks and over temperature by monitoring sensors within the pumps and providing early warning or disabling the pumps.
