The GARDENA submersible wastewater pump 20000 water sensor is a particularly efficient pump that provides high performance with low energy consumption. The integrated water sensor allows the resistive submersible pump not only for smooth operation in narrow shafts but also offers precise adjustable switch-on and switch-off heights, self-protection against dry run and pollution control. At an output of 750 W, the motor of the energy-saving drainage pump is extremely strong. With a pressure of 0.9 bar and a delivery height of 9 m, it can transfer 20000 liters of waste water per hour and is particularly efficient. The grain size of the dirt particles in water can be up to 35 mm. The innovative special feature of this drainage pump, the digital water sensor, offers further functions, which ensure, for instance, a reliable flood protection. During operation, the aqua sensor measures the water level, without having any direct contact to waste water. Practical LEDs show the current water level after measuring. The water sensor controls the pump in such a way that the previously set water area is adhered to. Programming is done via the intuitive touch panel. Along with the optional continuous run a 10-minute timer function is also available. Thanks to the simple hose connection system from GARDENA, different hoses can be connected to the submersible sewage pump 20000 at the same time with just one click. It is therefore possible to connect hoses with it with a diameter of 32 mm (1 ½), 38 mm (1 ¼) or 50 mm (2). Together with a G1 ½ thread, there are even more possibilities. This particularly efficient pump demonstrates GARDENA's 40 years experience in the fields of drainage, irrigation and domestic water supply, whether for ponds, building pits or the flooded cellars. GARDENA offers an extended warranty of 5 years after online registration.This text is machine translated.
