Our standard SmartBox Pump Start Relay family provides dependable control and pump protection for irrigation systems – up to 10 hp. The SmartBox offers shut-down protection from damages due to run-dry and deadhead – plus full compatibility with all major brands of AC lawn controllers and other start/stop devices to activate your pump when watering cycles begin.
The protection concept is easy – monitor the system for possible failure points and shutdown the pump before damage can occur. A pressure sensor monitors internal pressure to detect when run-dry or loss of prime conditions may damage seals or other pump components. A temperature sensor monitors the temperature of the running system. Under deadhead conditions, the water temperature will continue to rise while the pump runs - threatening the integrity of the pipework, seals and other pump parts.
The SmartBox relays offer peace of mind for contractors and property owners by protecting the pump, thus extending the pump life and reducing costly downtime and maintenance.
