The 3-chamber diaphragm pump is suitable for automatic and reliable supply of drinking water in motor homes. The unique diaphragm technology allows precise and controlled dosing. Each pump head has a non-return valve and a pressure switch control. This ensures that water flows immediately when the tap is opened. The pump is self-priming up to 3.1 m and has a 10 mm hose connection. It runs extremely quietly at a high flow rate due to special noise-absorbing material and a special seal on the pump head.
