CIRCULATOR GRUNDFOS CRE 3-5 1X230V TAAJUUSM

The Grundfos CRE series is a vertical, multistage centrifugal pump equipped with an integrated frequency converter, with suction and discharge ports on the same level. The pump head and base are made of cast iron. Other wet parts are made of stainless steel (EN 1.4301). The versatile CR series is suitable for pressure boosting applications such as in industry or waterworks and in building services for heat recovery systems. The pump motor has digital and analog inputs and outputs, as well as a fieldbus interface. For example, you can adjust the speed of a mixing pump by bringing temperature measurements directly to the pump, or maintain constant pressure by feeding pressure data to the pump. You can order the CRE pump with a pressure sensor pre-connected to the pump at the factory. E-pumps also feature additional functionalities similar to PLC logic. For example, you can limit the flow rate produced by the pump using an external flow meter and the FLOWLIMIT function. CRE pumps are typically used in applications such as heat recovery, pressure boosting, and any application requiring high head. E-motors are available for all models up to 22 kilowatts.
