Typical Specifications

Typical capacity

For this class of Grundfos CRIE pumps, flow rates commonly range from 10 to 40 m³/hr, depending on the specific model variant and head requirements.

Power supply

Units of this type typically operate on a three-phase electrical supply, commonly 400V, 50Hz, with integrated frequency converters allowing for variable speed control.

Motor power

Motor power for CRIE 3-series pumps generally falls within the 2.2 kW to 7.5 kW range, influenced by the required head and flow.

Contact materials

As stated, all contact parts are stainless steel, which is standard for hygienic applications and corrosion resistance in many industrial fluids.

Operating pressure

Maximum operating pressures for CRIE pumps can typically reach up to 16-25 bar, depending on the specific model and stage configuration.

Temperature range

Commonly, these pumps are designed to handle liquid temperatures from -20°C to +120°C, suitable for a wide range of industrial processes.
