Each module is mounted on a electrostatic epoxy painted steel frame in line with EN 12845 standard. Booster set assemblies are in an assembled module form with electrical panel cabling.
2. The pumps are activated automatically with a command from pressure switch and then they are deactivated manually.
3. Main pump modules have inlets that are suitable to be connected to 1" forward-feed tanks (operation tank) in case they will be operated by drawing water from underground tank (negative suction).
4. To prevent mechanical seals to be damaged during closed valve test operations, pump modules have the ability of back circulation to the water tank or the operation tank.
