A hydrophore installation is generally used to increase the existing drinking water pipe pressure. At the same time, such a set is used as a so-called break tank. In the case of a break tank, this is used instead of a check valve in the main water pipe to prevent backflow to the drinking water installation. In fact, it can be one pump with tank and control unit, but in case of varying pressures and/or capacities it can also be multiple pumps on the same tank and control unit. The capacity of the tank and pump(s) depends on the expected consumption, but can vary from an 80 liter tank capacity to a capacity of a number of cubic meters.
It is generally also the simplest pump in terms of material choices, sealing and bearings. This is actually because clean water has virtually no chemical effect, and only "rust" is a risk if you choose a ferrous material. Wear is also present to a lesser extent, simply put, because no wearing medium is pumped. (Water is clean), this type of pump is also often used in other purely clean liquid applications, partly because its simple composition makes it a relatively cheap pump.
The pump can be divided into three parts (plus the E-motor); the bearing bracket, the fluid part and the shaft seal(s).
