When water flows where it is not supposed to you need to act quickly in order to e.g. prevent larger damage to the home. The GARDENA Premium Dirty Water Pump 20000 inox is just the right pump if you need to quickly and powerfully transfer or drain a lot of water at once. Up to 20,000 litres per hour can be pumped, even with strongly dirtied water with particles of up to 38 mm. A Float Switch thereby ensures automatic cut-in and cut-out. Through a cable holder for the Float Switch, the cut-in and cut-out heights can be precisely and flexibly adjusted. If required, a plug-in device allows simple switching to permanent manual operation. Thanks to 10-metre-long power cable the practical and robust pump can be universally used - also in great depths. Highest demands on the premium model are fulfilled through the use of top-quality materials. For example, the stainless steel housing of the pump renders it highly robust with a long service life. Reliable pump operation is guaranteed by a low-wear pump impeller and a low-noise, maintenance-free capacitor motor with thermal protection switch. Thanks to the universal connection, 13 mm (1/2")-, 16 mm (5/8")-, 19 mm (3/4")-, 25 mm (1"), 38 1 ½- and additional 50 mm (2") - hoses can be connected to the pump.
