Vertical multistage centrifugal pump CR 5-8 A-FGJ-A HQQE 1.1 kW 3x230/400V 96511750

Multistage centrifugal pump for demanding applications

The CR 5-8 A-FGJ-A HQQE vertical multistage pump is an advanced solution for efficient water pumping in a wide range of industrial and utility applications. The pump's design, based on proven Grundfos components, guarantees reliability and long life even in harsh working conditions. The use of high-quality materials, such as cast iron and stainless steel, ensures resistance to corrosion and mechanical damage.

Construction and application

The CR 5-8 A-FGJ-A HQQE pump is designed to work with clean water or non-aggressive liquids. Its vertical design minimizes space, which is particularly important in installations with limited surface area. Thanks to its high energy efficiency (MEI index of 0.57) and IE3 class motor, the pump is characterized by low operating costs. It finds application in industrial water installations, irrigation systems, as well as in processes requiring water pressure boosting. It can also be used in fire protection systems and seawater installations – although the specifics of these applications should be taken into account.

Key features and benefits

• High efficiency: A nominal flow rate of 5.8 m³/h and a maximum head of 56.5 m allow the pump to be adapted to diverse hydraulic needs.
• Durable construction: The pump body made of cast iron GG 20 (GJL-200) provides strength and corrosion resistance. The impeller made of stainless steel 304 (1.4301) guarantees long life even when pumping liquids containing small impurities.
• Energy saving: A 1.1 kW motor with IE3 efficiency class minimizes electricity consumption, reducing operating costs.
• Reliability: Insulation class F and protection degree IP55 ensure safe and trouble-free operation in a wide range of ambient temperatures (-30°C to +60°C) and medium temperatures (-20°C to +120°C).
• Easy installation and maintenance: The compact design and flanged connections facilitate pump installation in existing hydraulic systems. The embedding length of 250 mm allows integration with various types of installations.
• Safety: The maximum operating pressure of 25 bar ensures safe operation of the pump even in systems with high pressure.
• Three-phase motor: 3x230/400V power supply makes the pump suitable for most industrial and commercial installations.
