Vertical multistage pumps – effective solutions for demanding applications

The CR 32-2 A-F-A-E HQQE vertical multistage centrifugal pump is an advanced solution for a wide range of industrial and installation applications. It is characterized by high efficiency, reliability and durability, making it an ideal choice for both professional installers and end users. The pump's construction, based on Grundfos' many years of experience, guarantees efficient operation in demanding conditions.

Construction and application

The CR 32-2 pump is designed to operate in systems for increasing water pressure, non-aggressive liquids, and in industrial installations. Made of high-quality materials, such as cast iron (housing) and stainless steel (impeller), it ensures corrosion resistance and long life. The in-line design with suction and discharge connections facilitates installation and integration with existing infrastructure. The pump is used in industrial water installations, washing and cleaning systems, as well as in applications related to process water treatment. The possibility of use in seawater installations highlights its versatility.

Key features and benefits

• High efficiency: Engine power of 4 kW and a nominal flow rate of 30 m³/h ensure efficient operation even with high water demand.
• Durability and reliability: The use of cast iron (GGG 50) for the pump housing and stainless steel (1.4301) for the impeller guarantees resistance to corrosion and mechanical damage.
• Wide range of applications: The pump performs perfectly in industrial installations, pressure boosting systems, and applications related to process water treatment.
• Energy saving: The motor with energy efficiency class IE3 minimizes electricity consumption, resulting in lower operating costs.
• Easy installation and maintenance: The compact design and standard connections (flange EN 1092-2) facilitate installation and integration with existing infrastructure.
• Safety: Protection class IP55 provides protection against dust and water jets, increasing safety in difficult environmental conditions.
• Temperature resistance: Operation in a range of ambient temperatures from -30°C to 60°C and a medium temperature from -30°C to 120°C allows the pump to be used in various working conditions.
• Insulation class F: Provides high thermal resistance of the motor windings, which translates into a longer service life.

The CR 32-2 A-F-A-E HQQE pump is an investment in a reliable and efficient solution that will meet the expectations of even the most demanding users. Its solid construction and high quality workmanship guarantee long-term and trouble-free operation.
