Vertical multistage centrifugal pump CR 3-12 A-A-A HQQE 1.1kW 3x230/400V 50Hz 96516599

Multistage vertical pump for demanding applications

The CR 3-12 A-A-A HQQE multistage centrifugal vertical pump is a robust solution for efficient water pumping in water supply, industrial and domestic systems. The pump design, with in-line connections, allows for easy installation on horizontal pipelines, minimizing space requirements. This device is characterized by high efficiency and reliability, making it an ideal choice for both professional installers and end users.

Construction and application

The CR 3-12 pump is designed to work with clean water or non-aggressive liquids. Made of high-quality materials – GG 20 (GJL-200) cast iron for the housing and 304 (1.4301) stainless steel for the impeller – it ensures long-lasting and trouble-free operation even in difficult conditions. It is intended for applications such as:

• Potable and utility water supply
• Irrigation systems
• Industry – pumping process liquids
• Fire protection systems
• Pressure boosting in installations

Key features and benefits

• High efficiency: A 1.1 kW motor with a speed of 2853 1/min provides efficient water pumping with a nominal flow rate of 3 m³/h and a maximum head of up to 79.1 m.
• Durable construction: The GG 20 cast iron housing guarantees resistance to corrosion and mechanical damage, and the stainless steel impeller ensures a long pump life.
• Safety: Insulation class F and protection degree IP55 ensure safe operation in various environmental conditions (ambient temperature from -30°C to 60°C).
• Easy installation: The compact design and in-line connections facilitate pump installation in existing pipeline systems. BSPP-G (ISO 228-1) threaded connections with a diameter of 1 inch (25 mm) ensure a tight connection.
• Energy saving: IE3 energy efficiency class motor minimizes electricity consumption, resulting in lower operating costs.
• Reliability: The pump is designed for long-term and trouble-free operation, which is confirmed by the high quality of workmanship and materials used. The minimum efficiency index (MEI) is 0.7, which indicates the high energy efficiency of the device.
• Three-phase operation: 3x230/400V power supply and 4.35A rated current allow connection to a standard three-phase electrical installation.

The CR 3-12 pump is an investment in a reliable and efficient water pumping solution that will meet the expectations of even the most demanding users.
