Water Pump Einhell GE-DP 18/25 Li

The Einhell GE-DP 18/25 Li cordless waste-water pump is a battery-powered pump for removing clean or waste water in garden and domestic applications. Part of the Einhell Power X-Change family, the pump is compatible with the system's 18 V batteries and chargers (battery and charger not included). The splash-proof, robust battery box protects the battery and can be mounted on walls, rain barrels or fences using the integrated wall bracket or fastening hook. The pump motor delivers 153 W and provides a maximum flow rate of 7,500 litres per hour with a maximum delivery pressure of 0.5 bar. It can be immersed up to 4 metres using the 5 m connection cable and handles dirt particles up to 25 mm. The pump has two power settings—ECO for longer runtime and BOOST for maximum output—and requires a minimum water level of 40 mm to start, pumping down to a residual water level of 35 mm. The unit includes a 42 mm (1 1/4" AG) pressure connection and a universal adapter for 25/32 mm hoses with 1" AG (33.3 mm).

Advantages

The cordless design allows flexible use away from mains power while compatibility with Power X-Change batteries provides system versatility. The splash-proof battery box with cable rewind keeps the connection cable organised and enables safe mounting. Two performance modes let you choose between extended runtime or maximum delivery capacity. Lightweight construction with a double-sided carrying handle ensures easy transport and handling. The included hose adapter and standard pressure connection make fitting existing hoses straightforward.

Suitable for

• Pumping garden ponds, flooded cellars and rainwater barrels
• Emptying water features and small basements

How to use

Mount the splash-proof battery box where convenient (wall, rain barrel or fence) using the integrated bracket or fastening hook, insert a compatible 18 V Power X-Change battery and rewind the 5 m connection cable as needed. Place the pump into the water up to the allowable immersion depth, ensuring the water level is at least 40 mm so the pump can start. Select ECO mode for longer runtime or BOOST mode for maximum output. Monitor operation and avoid running the pump dry; the pump will pump down to a residual water level of approximately 35 mm. After use, remove the battery and store the pump and battery box in a dry place.

Usage recommendations

Do not use the pump with aggressive or flammable liquids. Clean the impeller and filter regularly if pumping water with suspended solids, and check hose connections before each use. Use only compatible Power X-Change batteries and chargers to ensure proper performance and safety.
