KSB will show the latest version of its motor-mounted speed control system for centrifugal pumps at this year's Hannover Messe in April.

The system is designed specifically for industrial applications and makes it possible to reduce energy costs by matching pump output to actual demand. All parameters are preset at the factory based on the specific pump and motor data. The time required to commission the pump set therefore does not exceed that of a non-controlled unit.

Up to six PumpDrives can be combined into a controlling unit via plug-in bus lines, which allows the user to operate six pumps in parallel. This unit starts and stops the pump sets in line with demand while ensuring that the operating load is distributed evenly.It corrects the failure of individual components with no interruption.

A dynamic pressure setpoint compensation function simulates friction losses in the piping between pump and consumer. The pump then, in case of low flow operation, only generates the discharge pressure required to compensate for the friction losses in the piping towards the consumer installation. This, in turn, provides for additional energy savings if it is not possible to take measurements at the point of lowest pressure.

Field bus modules are available in the Profibus DP, Modbus RTU, LON, BACnet TCP/IP, ProfiNet and Ethernet configurations. The integrated wireless module allows users to connect to an iPhone via Bluetooth to communicate with the system and configure settings as required. The application makes maintenance much easier to coordinate and expedites commissioning of the pump as well as offers an option for managing application-specific data records.

Hannover Messe 2014 takes place during April 7-11.
