In irrigation applications, pumps need a device that signals to the system to start moving water in the direction of the pump. That's exactly the function that a pump relay switch performs. You can see how crucial this pump part is to the operation of the automatic system. Save on your replacement parts at PlumbersStock and take advantage of our wholesale prices.

A pump relay switch is often seen in well applications to pump water from the well to your home or building. A pump relay switch is used with higher horsepower submersible pumps and signals to the pump when to turn on and off.
Pump relay switches can be thought of as buffers between the pump pressure control switch and a heavy-duty water pump. For lighter water pumps, the on/ off pump action is controlled by the pressure control switch directly. However, the problem arises when the water pump has too high a voltage/amperage combination. Large horsepower water pumps can easily draw more than 15A—enough amperage that would cause the pressure control switch to be burned up rapidly.
