The Variable Flow Blagdon Amphibious IQ 6000-12000 pump with Digital Motor lets you control the flow! This low maintenance yet high performance energy saving pond pump is designed to work with digital motor technology that uses around 30% less energy than similarly priced pumps. The flexible power usage control and display with touch button stop, start, increase or decrease power and flow helps to cut costs and save money. It is suitable for waterfalls and filters, combining low maintenance with high performance. The motor protection system will pause and display a message if the pump detects the motor is clogged or jammed, allowing you to clean the impeller or rotor. Once the clogging has been removed, the pump can safely restart. The run dry protection system detects insufficient water, pauses the pump, and displays a warning. The pump will automatically restart when the water level is safe again. On initial start-up, the controller will gradually increase the power supplied to the pump to its pre-set power position, in turn gradually increasing the flow rate. This reduces pump wear and stress on pipework and filters fitted to the system, decreasing the risk of leaks or damage.
