Bell & Gossett (B&G), a brand of Xylem, recently launched its Parallel Sensorless Controller, a device that provides advanced system staging of up to eight pumps in a parallel configuration to maximise system efficiency, said Jordan Ruff, Product Line Manager, Americas, Xylem. 

Speaking on the development, Ruff said: “Parallel pumping is a proven method for improving efficiency in pumping systems with higher control heads. It can control up to eight pumps, it gives users greater options in optimising system efficiency and it replaces the need for a wired differential pressure transducer.”  

Highlighting the features of the solution, Ruff added that the device comes with a 5.7-inch touchscreen that displays real-time graphical feedback and enables energy modelling. It relies on pump-specific algorithms, such as speed, torque and power data to predict where the pump operates on its curve, and it meets the ASHRAE 90.1 system efficiency requirements.
