Grundfos CRE is intended for systems where the required flow or pressure changes during operation. Typical duties include pressure boosting, water supply, washing, water treatment, boiler feed, temperature control and industrial processes. Variable-speed operation is relevant where maintaining the required process condition without continuously running at one fixed duty point can improve control and reduce unnecessary hydraulic losses.
CRE combines the non-self-priming vertical multistage CR pump platform with an integrated variable-speed drive and control capability. As on the CR platform, the inlet and outlet are arranged on the same level, while the pump stack provides multistage head generation. The drive can adapt speed to control requirements such as pressure, flow or temperature, depending on the selected configuration and sensors.
AxFlow publishes CRE performance data up to 244 m³/h, differential pressure up to 30 bar, head up to 266 m and liquid temperature up to 120 °C. These values define the published series envelope and vary by size and configuration. The actual duty point, materials, seal, control mode and communication requirements must be verified for the application.
Demand-based speed control can reduce throttling losses and unnecessary full-speed operation when system demand varies. The CR-based hydraulic construction provides a familiar service platform, while integrated control can reduce the need for separate drive components. Correct sensor, control and hydraulic selection helps maintenance teams avoid unstable operation and supports predictable service planning and lifecycle cost.
