Grundfos CR3-36 Multistage pumps

• 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 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.

• 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?

Centrifugal pumps are widely regarded as reliable workhorses in laboratory and pharmaceutical applications. Buyers typically value their smooth operation, low maintenance requirements, and consistent performance across diverse fluid handling tasks. When purchasing used models, buyers commonly prioritize checking seal condition, impeller integrity, and motor functionality. Industry sentiment favours units from established manufacturers with documented service histories. Key strengths include durability, cost-effectiveness compared to new equipment, and suitability for both routine and demanding applications.
