ABB ACQ580 drives running as a multi-pump

That is the question  - when you have the advanced capability of an ABB ACQ580 multi-pump system on your side.

EDC recently installed two 55kW ACQ580s, digitally linked, at a Scottish Water site where the tank level signal was dropping off intermittently, resulting in a loss of control on the pumps. The addition of the new drives not only significantly reduced high pressure transients but provided the site with a bespoke, intelligent, independent control system including: Pi control of level (drive will speed up/slow down to maintain a constant level), Start Duty Pump, Start Assist Pump, Start Standby Pump, Duty Rotate of Pumps, Balance run hours of Pumps. The ABB ACQ580 series, poetry in multi-pump motion.
