The new systems are designed for large flow rates with a maximum flow rate per system of 960 m3/h and the maximum pump head is 160 m as standard.
The first pump is started by a pressure drop in the piping when a consumer installation is opened. The systems’ microprocessor control unit (Booster Command Pro+) starts and stops the pumps in line with demand using either cascade control for the F variant or a frequency inverter for speed control for the VC and SVP.
When water consumption stops, all pumps are ramped down one after the other once the stop pressure has been reached. This ensures that the individual pumps operate only in line with actual demand. If a pump has not been operated for over 24 hours, the microprocessor control unit initiates a test run for this pump. Should lack of water occur in the inlet, the system stops automatically to prevent damage caused by dry running.
A Modbus RTU interface facilitates connection to external communication devices. For transmitting warnings or alerts to a higher-level control station, the standard configuration has two volt-free contacts on terminals in addition to other optional signal terminals.
The pressure booster systems can be connected to the KSB Delta FlowManager app which shows the current status of the pumps, the pressures on the suction and discharge side, and the programmed parameters. The SVP version is fitted with high-efficiency IE5 synchronous reluctance motors of the Supreme type series and the PumpDrive variable speed system. The F and VC variants are equipped with IE3 motors.
