Water Pump Einhell AQUINNA 18/28

The Einhell AQUINNA 18/28 cordless garden pump is a battery-powered pump from the Power X-Change family designed for moving water where no mains power is available. It delivers up to 2,800 litres per hour, reaches a maximum delivery height of 25 metres (2.5 bar) and can suck water from depths down to 6 metres. The compact pump weighs around 2.55 kg, features a central carrying handle, two metal threaded connections (G1) and is supplied without battery or charger.

Advantages

The pump offers two operating modes: BOOST for maximum output and ECO for extended battery runtime at lower delivery pressure. An integrated overload protection switches the unit off in case of motor overheating. A large water filler screw simplifies initial priming and a drainage screw on the underside allows complete emptying for frost protection. The battery compartment is covered to protect the inserted battery from splash water and dust, and fixing holes enable secure permanent mounting.

• Pumping and transferring garden water
