KSB pumps for University of Pretoria

3rd Quarter 2018 News & events

KSB Pumps and Valves has assisted the University of Pretoria in the construction of a large controlled temperature test unit, which will form the backbone of ongoing research into heat transfer, fluid mechanics and thermodynamics. The impressive unit will allow students to plug directly into hot, moderate or chilled liquids to use on research projects.

Chairman of the School of Engineering and head of Mechanical and Aeronautical Engineering, Professor Josua Meyer says the multimillion rand project was partly funded with donations from industrial companies like KSB Pumps and Valves. He explains that the system relies on temperature monitoring of flow loops where water is conditioned through the relevant heat pumps and chilling units at near boiling or lower temperatures, as well as subzero degree glycol. The user demand within each loop is controlled using a system of pumps, variable speed drives, pressure transducers and special valves to allow up to eight experiments to plug in simultaneously without affecting either the flow rate, working pressure or temperature of the unit.

The university specified five Etanorm 50/32/250 pump sets with 3 kW, 2,2 kW and 1,5 kW motors.

PLC control ensures that all parameters are checked and balanced to ensure the system delivers fluid at the right temperature setpoints and flow conditions 24 hours a day. With the system up and running, Meyer concludes that the project is proving to be a great success with numerous research projects already plugged in.
