Grundfos CM5-4 A-R-I-E-AQQE F-A-A-N Horizontal Multi-Stage Booster Pump, Water/Coolant, 3-Phase, End Suction

Grundfos CM5-4 A-R-I-E-AQQE F-A-A-N Horizontal Multi-Stage Booster Pump

The Grundfos CM5-4 A-R-I-E-AQQE F-A-A-N is a robust and highly efficient horizontal multi-stage centrifugal pump, part of Grundfos' renowned CM (Centrifugal Modular) series. This model is engineered for reliable pressure boosting and liquid transfer across a wide array of applications, including domestic and commercial water supply, light industrial processes, cooling systems, and irrigation. Featuring a modular design, the pump provides excellent hydraulic performance, low noise levels, and a compact footprint for versatile installation.

The "5-4" in the model designation indicates a nominal flow of 5 m³/h and 4 impellers, ensuring consistent pressure and flow delivery. Constructed with high-quality materials, the pump's components—including impellers, intermediate chambers, and shaft—are made of stainless steel (indicated by 'A-R-I-E'), offering exceptional corrosion resistance and extended operational life when handling clean liquids within a temperature range typically from -20°C to +120°C.

This specific variant is equipped with an efficient 1.1kW (1.5 HP) 3-phase motor, operating at 400V and a speed of 2900 RPM. The motor is designed to deliver consistent power, ensuring optimal pump performance. The "AQQE" mechanical shaft seal specification denotes a high-quality sealing arrangement, typically involving Silicon Carbide/Silicon Carbide with EPDM rubber, providing superior durability and leak-free operation. The "F-A-A-N" further specifies standard flanged connections and robust motor details suitable for industrial integration. The CM5-4 is designed for energy efficiency, contributing to reduced operational costs while delivering reliable and maintenance-friendly performance.
