Automatic Pump Controller provides automatic stop/start on demand and incorporates a flow monitor to protect against dry run. The automatic pump controller eliminates the need for any manual switching of pumps installed for the purpose of pumping water from a reservoir to an overhead tank. It automatically switches on the pump when the water level in the tank falls below a certain low level, provided the water level in the reservoir is above a certain level.

Automatic pumps are used to operate automatically. Automatic pumps are more independent when compared to manually operated pumps. They can be either pressure controlled or flow controlled or circuit controlled. Cycling times are completely controlled by the model once the desired suction strength has been selected and the unit is switched on.

Automatic Recirculation Valve utilizes three valve elements to accomplish smooth and no disruptive switching of fluid flow between main fluid flow & recirculation fluid flow. An automatic recirculation valve has an inlet, a main outlet and a recirculation outlet. This automatic recirculation valve is used in recirculation lines of centrifugal pumps.
