The Lily 5-chamber Smart Series water pump has a very high, variably adjusted flow rate. The water pressure is sensed by an integrated sensor. The signals are relayed to the intelligent microprocessor-controlled electronics, which control the motor speed and the flow rate. The required amount of water is metered exactly as needed. The pump starts very quietly and does not splash. Protection against humidity, over- or undervoltage. Backflow protection up to 20 bar. Connection with quick fittings on 1/2" external thread (included).
