Water Pump Einhell AQUINNA 36/38 F LED

The Einhell AQUINNA 36/38 F LED cordless garden pump is a battery-powered water pump for use around the home and garden where no mains connection is available. Part of the Power X-Change system, the pump uses 36 V Twin-Pack technology (two 18 V batteries) for maximum power. It delivers up to 3,800 litres per hour, reaches a maximum delivery height of 37 metres (3.7 bar) and can suck water from depths up to 6 metres. The pump has two operating modes (BOOST for maximum flow and ECO for extended battery life), an LED charge level display for both batteries, a large water filler screw for priming, a water drainage screw for winter protection and a transparent pre-filter housing with an integrated non-return valve to monitor filling and filter contamination.

Advantages

The pump offers cordless operation with the flexibility of the Power X-Change battery system and Twin-Pack performance. Two selectable power levels allow balancing between maximum delivery pressure and longer runtime. The transparent pre-filter housing provides visual indication of water level and dirt, while overload protection prevents damage from overheating. A central carrying handle and fixing holes enable easy transport and secure installation. The robust metal threaded connections and protected battery compartment increase durability.

Suitable for

• Filling and transferring water between barrels, tanks or ponds
• Garden irrigation where no mains power is available
• Emergency water removal from basements or flat areas (short-term)

How to use

Install two compatible Power X-Change batteries and check the LED charge level display before operation. Connect the delivery hose to the G1 threaded outlet and position the suction hose or inlet in the water source. For first use or after emptying, open the large water filler screw to prime the pump. Choose BOOST mode for maximum flow or ECO mode to prioritise battery life. After use, open the underside water drainage screw to empty the pump if it will be stored in freezing conditions. Clean the transparent pre-filter housing and filter element regularly to ensure unobstructed flow.

Recommendations

Use only compatible Power X-Change batteries and chargers. Do not operate the pump dry for extended periods. Regularly inspect and clean the pre-filter and ensure the non-return valve is functioning. Store the pump drained and protected from frost; batteries should be removed for long-term storage.
