PumpDrive: flexible speed control for maximum efficiency
Safe and reliable pump operation
Reliable pump operation requires continuous monitoring of the installation. The pumps' operating status has to be checked frequently. PumpDrive therefore continuously records and processes values, readings and data to monitor the permissible operating range at all times and ensure system availability.
Special features of PumpDrive :
Characteristic curve control and flow rate estimation
PumpDrive monitors the pump’s characteristic curves and estimates the current operating point on the basis of the motor input power and the current speed. This, in turn, allows PumpDrive to detect operation outside the permissible range such as extremely low flow, dry running or overload conditions. Predefined settings allow messages to be output in the case of extremely low flow or overload conditions. Depending on the settings, the pump set is stopped, which protects pumps against failures and damage resulting from operation in an impermissible range.
Continuous flow rate estimation is another essential PumpDrive feature. The flow rate is estimated on the basis of power measurement and the characteristic curve function. The estimated flow rate provides essential information for dynamic pressure compensation and other important functions.

Pressure boosting functions package: constant system pressure thanks to PumpDrive
Redundancy by dual pump management
Thanks to integrated dual pump management, the predefined setpoint for the system is ensured at all times by way of two identical pumps. A distinction is made between two operating modes.
Flexibility in diverse applications
As the new PumpDrive has been perfectly matched to the motors of KSB pumps, it can be mounted directly on motors up to ratings of 55 kW. Benefit of motor mounting: retrofits eliminate the need for installation space in the control cabinet and the search for a suitable section of wall.
