I use the pump as an isolated solution for handwaking at home in the bathroom. That is, It pumps the water out of the 35 liter canister, which is also available from SVB, "up" to the sink via a 13mm hose (approx. 1m height difference). The hose is temporarily attached to the tap with a cable tie. To wash your hands without soap, just step on the pump. With a little soap you need 2 strokes. For heavily soiled hands, more accordingly. The advantages of this solution are perfect hygiene after using the toilet, since there is no need to operate a tap with your hands (keyword "EHEC") and extremely low water consumption because the water can be dosed precisely. A little patience is required to fill vessels with water using the pump. The specified max. 8L / min are unrealistic, because you cannot step on the pump like crazy, but after a stroke you have to wait a short time (1-2 seconds) until the pump has reached the starting position again. In one test, it took me exactly 40 seconds for 1 liter of water. As an area of application, I can also imagine outhouses (e.g. in the garden) to create better hygiene.
