The system has a compact design and integrated suction and discharge nozzles with pipe threads and direct connection to the mains via a plug. The two-pump system generates a maximum head of 60 m, and when necessary, the stand-by pump can be started up to meet peak load demand. Each of the two pumps has its own frequency inverter, which helps ensure that energy consumption does not exceed the amount required to supply pressure to the connected hydraulic consumers. The frequency inverters also allow the pumps to be started up and slowed down smoothly, improving system reliability.

The maximum system discharge pressure is 10 bar and the maximum permissible inlet pressure is 6 bar.
KSB’s Hya-Compact system is equipped with variable-speed, energy-efficient IE2 motors, which means that users can save up to 35% of energy compared with conventional booster systems. The housing delivers low-noise operation, while the internal piping arrangement avoids regions where fluid can stagnate, thus inhibiting the growth of germs. The booster package system comes with a large display panel on which all important system data is presented in clear text. Standard fault messages can be transmitted to a building management system, and there is a leakage reporting feature.
