Using either float or conductance probes, Littelfuse offers relays that control conductive liquid pumping operations ideal for both your pump-up or pump-down applications. Plus, our 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.
