Silent running and powerful technology
Introducing incredibly low noise level pumps, delivering more power. Use the GARDENA Pressure Tank Unit 3900 Silent as an integral part of your water supply in the home and garden. It allows you to use rainwater or well water for irrigating the garden or as service water in your household, for example for toilets or for the washing machine. The Pressure Tank Unit switches on automatically depending on the water demand and then switches off again. Since it can draw on the large storage tank, it operates extremely quietly and cost-effectively. The pressure pump is powerful with a delivery head of 43 metres (4.3 bar) and a flow rate of 3900 litres per hour. The moderate power consumption of only 650 watts shows the high efficiency of the Pressure Tank Unit developed in Germany. It is comparatively quiet in operation, as the noise-reducing plastic housing reduces the volume to a maximum of 48 dB(A) sound pressure in 5m distance. The rubber feet allow the pump to stand firmly and ensure low-vibration operation. The base can also be screwed to the floor in a concealed manner. A high-performance membrane is installed inside the pump's 21-litre water tank. This makes the tank maintenance-free for at least five years, so that neither air needs to be refilled nor the membrane replaced. 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. The result is durability in all components and the pump is well protected. Pressure indicator and pressure switch are integrated in the design and allow compact installation dimensions . A ceramic sealing system and the integrated filter ensure a long service life. The filter prevents dirt particles from getting into the power-saving pump or application equipment. The practical pressure gauge shows you the current pressure in the storage tank at all times and the non-return valve is already integrated, so that the Pressure Tank Unit 3900 Silent is ready to go straight away. The durable Unit is made of high-quality materials such as stainless steel for the drive shaft and for the two connections. The thermal protection switch protects against motor overload. The large filling opening and the drain valve ensure that you can fill it particularly easily and protect it from frost.
