Grundfos CRNE19 Vertical multistage pump

• Water supply and boosting in commercial buildings and industrial processes.
• Industrial liquid transfer, circulation, and pressure boosting.
• Water treatment systems, including filtration and reverse osmosis.
• Heating, ventilation, and air conditioning (HVAC) systems.
• Light industrial washing and cleaning systems.

Typical capacity

For this class of Grundfos CRNE19 pump, flow rates typically range from 1 to 3 cubic metres per hour, with heads up to 100 metres or more depending on the number of stages.

Power supply

Units of this type commonly operate on three-phase electrical supplies, typically 400V, 50Hz, though specific motor ratings will vary.

Materials in contact with liquid

As stated, high-grade stainless steel is used for parts in contact with the liquid, which is common for CRNE series pumps, ensuring corrosion resistance.

Mounting configuration

This is a vertical, inline pump, meaning inlet and outlet ports are at the same level, facilitating compact installation within piping systems.

Motor type

CRNE models typically feature an MGE motor with an integrated frequency converter, allowing for variable speed control and energy efficiency.

Connection type

Commonly, these pumps feature standard flange connections, with specific sizes dependent on the pump's flow capacity.

• What does 'multistage' mean for a pump?

  A multistage pump contains multiple impellers in series. This design allows the pump to generate higher pressures (head) than a single-stage pump for a given flow rate.

• What are the benefits of a vertical inline design?

• Why is stainless steel important for pump wetted parts?

• What does 'never been in production' imply for a used pump?

• How does the integrated frequency converter (MGE motor) benefit operation?

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.
