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?

A 3kW motor is suitable for a range of light to medium industrial applications, particularly where moderate flow rates and higher pressures are required. Its suitability depends on the specific process demands.

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

Stainless steel construction makes these pumps suitable for a wide range of non-corrosive and mildly corrosive liquids, including potable water, treated water, and some food-grade fluids. Always check chemical compatibility for specific applications.

What maintenance is typically required for these pumps?

Routine maintenance typically involves checking seals for leaks, inspecting bearings for noise or wear, and ensuring the motor is running efficiently. Regular servicing helps prolong the pump's operational life.

Can this pump be used for viscous liquids?

Grundfos CR pumps are primarily designed for low-viscosity liquids like water. Pumping highly viscous liquids may reduce efficiency and could require a larger motor or a different pump type.

Typical context for this category of equipment. Always confirm specifics with the seller.

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.

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.

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.
