• Powerful and energy efficient: developed in Germany, powerful with a power consumption of only 650 watts, high efficiency with a flow rate of 3900 liters per hour at 4.3 bar power pressure and lower power consumption
• Comparatively quiet at 75 dB(A) thanks to the innovative plastic housing and rubber feet for a secure, low-vibration stand
• Integrated pre-filter protects against dirt particles in the water and thermal protection switch protects the motor from overload
• High-quality materials for longevity: stainless steel for the two connections and the drive shaft, ceramic seal, membrane in the 21 liter tank
• The powerful and efficient 3900 Silent domestic waterworks from GARDENA is an integral part of the water supply in the home and garden. It allows the use of rain or well water to irrigate the garden or as domestic water, for example for toilets or the washing machine. The domestic waterworks automatically switches on and then off again depending on water requirements. Since it can use the large storage space, it works extremely quietly and cost-effectively.

The pressure pump is powerful with a delivery head of 43 meters (4.3 bar) and a flow rate of 3900 liters per hour. The moderate power consumption of only 650 watts shows the high efficiency of the domestic waterworks developed in Germany. The noise-reducing plastic housing reduces the volume to 75 dB(A) sound pressure at a distance of 5 m, so that the pump is comparatively quiet in operation. The rubber feet ensure that the pump stands firmly and operates with little vibration. The base can also be screwed concealed to the floor.

A high-performance membrane is installed inside the pump's 21 liter water tank. The inner skin of the tank is made of a waterproof, multi-layer material that protects the housing from corrosion. The integrated coupling between pump and tank is made of stainless steel. This makes it particularly durable, well protected and efficient. In addition, the pressure indicator and pressure switch are integrated into the design and ensure compact installation dimensions.

A ceramic sealing system and the integrated filter ensure a long service life. This prevents dirt particles from getting into the energy-saving pump or application devices. The practical pressure gauge indicates the current pressure in the storage tank at all times and the check valve is already integrated, so that the 3900 Silent domestic waterworks is ready to use straight away.

The durable domestic waterworks is made of high-quality materials such as stainless steel for the drive shaft and the two connections. The thermal protection switch also protects the motor from overload. The large filling opening and the drain valve make it particularly easy to fill the domestic water system and protect it from frost.
