BL booster systems are COMPACT constructions of two up to six same pumps. The number of pumps is calculated based on the total water cosuption of the main and that one pump can cover water consumption in periods of low need. Operation of the systems is achieved with pressure sensors and electronic control based on ciricular function of the pumps as well as parallel operation in case of two pumps. For systems with more than two pumps PLC control is included.
BL systems achieve steady state operation at installation where water supply has large variations:
