The Grundfos CRE 90-2-1 A-F-A-E-HQQE is a three phase vertical multistage pump with integrated inverter. The Grundfos CRE range are based on the popular CR series of vertical multistage pumps, but with the added benefit of an integrated variable speed pump controller, which regulates the speed of the pump according to a target pressure point, measured by a pressure transducer. This can lead to significant savings in applications where the pump's duty is not constant. Because the inverter is integrated, there is no additional wiring required. Note: a Grundfos GO device is required to commission these pumps.
