Grundfos CR3-36 Multistage Pumps

Applications & Use Cases

• Used for pressure boosting in water supply systems.
• Suitable for industrial liquid transfer and circulation.
• Applied in washing and cleaning systems requiring high pressure.
• Utilised in light industrial process water applications.
• Can be integrated into temperature control systems.

Typical Specifications

Typical flow rate

For this class of equipment, flow rates commonly range from 1 to 5 m³/h.

Typical head

Units of this type typically offer heads up to 100-150 metres.

Power supply

This unit features a 3kW motor. Grundfos CR pumps commonly operate on 3-phase electrical supplies (e.g., 400V).

Construction material

This unit is stainless steel, which is standard for many CR series pumps, offering good corrosion resistance.

Speed

The listed speed of 2902 RPM is typical for a 2-pole motor operating on a 50Hz supply.

Footprint

Multistage centrifugal pumps of this size typically have a relatively compact vertical design, saving floor space.

Temperature range

Commonly, these pumps can handle liquid temperatures from -20°C to +120°C, depending on seal and material configurations.

Frequently Asked Questions

• What does 'multistage' mean for a pump?

  A multistage pump has multiple impellers in series, allowing it to generate higher pressures than a single-stage pump with the same flow rate. This makes it suitable for applications requiring significant head.

• Is a 3kW motor sufficient for industrial use?

• What kind of liquids can a stainless steel Grundfos CR pump handle?

• What maintenance is typically required for these pumps?

• Can this pump be used for viscous liquids?
