GARDENA 25000 Submersible Dirty Water Pump, 1100 W, 25000 l/h, Stainless Steel, Black

The GARDENA 25000 Submersible Dirty Water Pump runs on AC mains power and is used for draining flooded basements, garden ponds, and construction pits. It is designed as a dedicated dirty water pump and is placed directly into the flooded area. An 1100 W motor drives the unit, moving high volumes of water steadily. The pump delivers up to 25,000 litres per hour, clearing large bodies of standing water quickly. It also achieves a maximum delivery head of 11 metres, giving enough vertical lift to draw water out of deep cavities.

The housing is made of stainless steel, giving the pump the structural resilience needed for continuous indoor or outdoor use. The unit weighs 7.1 kg and has an integrated carrying handle for moving it between sites. A 10-metre H07 RNF power cable provides sufficient reach from a mains socket, so an extension lead is not usually required. Water extraction is controlled by an adjustable float switch that turns the pump on or off automatically according to the water level. These features allow the pump to run unattended during extended drainage jobs.

• Maximum solid particle size of 38 mm – handles mud, stones, and debris without clogging.
• IPX8 waterproof rating – keeps electrical components safe during continuous submersion.
• Maximum immersion depth of 7 m – allows the pump to be placed at the bottom of deep construction pits or basement reservoirs.
• Operating pressure of 1.1 bar – maintains steady upward water flow against gravity.
• G1 connecting thread with 1/2-inch suction port – provides standard fittings for straightforward hose attachment.
• Maximum water temperature of 35 °C – safely handles warm stagnant water in summer outdoor conditions.
