Water Works
BG-WW 1140 NN


The BG-WW 1140 NN domestic waterworks is a powerful and reliable helper which enables clear water to be delivered from reservoirs, wells and shafts for use as service water in irrigation systems, washing equipment, toilet flush systems and much more besides. With its 1,100 W motor, the pump achieves a delivery rate of up to 4,000 liters of water per hour. Like the pump housing, the pressure vessel of the BG-WW 1140 NN is made of corrosion-resistant stainless steel and has a 20 liter volume, so the pump does not start up each time water is drawn off. An integrated pressure switch will activate the pump when the pressure drops and deactivate it again when the pressure returns to maximum. On the integrated pressure gauge you can read off the pressure at a glance. The pump is filled by means of a water filler screw. A water drain screw is provided for user-friendly emptying of the residual water.
