Grundfos CRNE19NFGJAEHHQ Vertical multistage centrifugal pump

• Water supply and boosting in commercial and industrial buildings.
• Industrial process water circulation and transfer.
• Washing and cleaning systems requiring high pressure.
• Temperature control and HVAC systems.
• Light industrial liquid transfer applications.

Typical capacity

For this class of Grundfos CRNE pump, capacities commonly range from approximately 2 to 20 m³/h, depending on the specific model variant and head requirements.

Power supply

Units of this type typically operate on three-phase electrical supplies, commonly 400V, 50Hz in the UK, though single-phase options may exist for smaller models.

Materials in contact with liquid

As indicated, high-grade stainless steel is commonly used for wetted parts in CRNE models, offering good corrosion resistance for various liquids.

Motor power

Motor powers for CRNE pumps vary widely based on performance requirements, typically ranging from 0.37 kW up to 22 kW or more for larger units.

Inlet/outlet configuration

CRNE pumps feature inline ports, meaning the suction and discharge connections are on the same level, simplifying pipework installation.

Control features

CRNE models typically include integrated variable frequency drives (VFDs) for precise flow and pressure control, often with sensor integration.

• What does 'vertical multistage' mean for this pump?

  Vertical multistage refers to the pump's design where impellers are stacked vertically, allowing for higher pressure generation with a compact footprint. It is suitable for applications requiring significant head.
