Pressure Pump Einhell AQUINNA 36/34 3.7 bar 3400 l/h

The Einhell cordless garden pump AQUINNA 36/34 is a battery-powered pressure pump designed to move water where mains power is not available. It belongs to the Power X-Change family and uses 36 V Twin-Pack technology by combining two 18 V batteries (batteries and charger sold separately). The pump delivers up to 3,400 l/h, reaches a maximum delivery height of 37 m (3.7 bar) and can suck water from depths up to 6 m. A large filling screw simplifies initial priming, and a drain screw on the underside allows easy emptying for frost protection. The pump includes a water level indicator and overload protection to prevent dry running and motor overheating. Two robust metal threaded connections, a central carrying handle and fixing holes for permanent installation are provided.

Advantages

The cordless design enables flexible use in locations without mains power. Twin-Pack technology provides higher power by combining two Power X-Change batteries. Two operating modes—BOOST for maximum pressure and ECO for extended battery runtime—allow adaptation to different tasks. Integrated water level indicator and drain screw simplify maintenance and winter storage. Overload protection automatically switches the pump off in case of overheating to avoid damage. The device is lightweight and portable with a central handle and can be fixed in a permanent position via mounting holes.

Suitable for

• Garden irrigation from barrels, ponds or tanks
• Draining rainwater, pools or flooded areas
• Water transfer tasks on allotments and smallholdings
• Use where no mains power is available

How to use

Fit two compatible 18 V Power X-Change batteries (not included) according to the manufacturer instructions. Fill the pump via the large filling screw before the first start to ensure correct priming and check the water level indicator to avoid dry running. Select ECO mode for longer runtime at lower pressure or BOOST mode for maximum pumping power. After use, drain the pump through the underside drain screw to empty it completely when preparing for frost or storage. Use the central carrying handle to transport the pump and the fixing holes to mount it in a permanent location if required.

Recommendations

Use only suitable Power X-Change batteries and a compatible charger. Do not operate the pump without sufficient water in the housing to prevent dry running. Drain and store the pump frost-free during winter. Keep the battery compartment protected from direct water ingress and clean threaded connections before attaching hoses.
