Vertical multistage centrifugal pump CR 5-3 A-A-A HQQE 0.55kW 3x230/400V 50Hz 96516976

Vertical multistage pump – performance and reliability in one

The CR 5-3 A-A-A HQQE vertical multistage centrifugal pump is an advanced solution for a wide range of industrial and domestic applications. Designed by Grundfos, it combines high efficiency, reliability and durability, offering optimal operating parameters in various conditions. This device is ideal for applications requiring efficient liquid pumping, where installation space is limited.

Design and application

The CR 5-3 pump is characterized by a compact vertical design, which simplifies installation and minimizes space usage. Made of high-quality materials, such as cast iron (housing) and stainless steel (impeller), it ensures long-lasting and trouble-free operation even in demanding environments. It is designed for pumping clean water or non-aggressive liquids, and its versatility allows for use in industrial water installations, washing and cleaning systems, as well as in seawater installations. Thanks to the possibility of adapting the internal materials of the pump, it can also be used for pumping acids and alkalis, as well as in ultrafiltration or reverse osmosis systems.

Key features and benefits

• High efficiency: A nominal flow rate of 5.8 m³/h and a maximum head of 22 m guarantee efficient operation in various systems.
• Durable construction: The housing made of cast iron GG 20 (GJL-200) and the impeller made of stainless steel provide corrosion resistance and long life.
• 0.55 kW motor: Provides sufficient power for efficient pump operation while maintaining energy saving – the energy efficiency class of the motor is IE3.
• Versatility: Can be used in a wide range of installations – from industrial to domestic.
• Compact dimensions: The vertical design minimizes space usage, making installation easier even in tight spaces.
• Standard connections: Internal gas tapered thread BSPP-G (ISO 228-1) on both sides facilitates integration with existing installations.
• Protection class IP55: Provides protection against dust and water jets, allowing operation in harsh environmental conditions.
• Continuous operation up to 120°C: The pump can operate with liquids up to 120°C, which expands its range of applications.
• Low MEI value: The minimum efficiency index (MEI) of 0.57 indicates relatively high energy efficiency of the pump – although it is not the highest value available on the market, it provides a reasonable compromise between price and energy efficiency.

The CR 5-3 A-A-A HQQE pump is a solid solution for professionals and users looking for reliable equipment for pumping liquids in various applications. Its durability, efficiency and versatility make it an investment for years to come.
