The CR range offers pumps of unmatched reliability that can be intelligently tailored to suit an infinite variety of applications. Since Grundfos invented this type of multistage in-line pump in 1972, many imitations have appeared on the market. However, four decades on, this latest generation of CR pumps, with their traditional efficiency, reliable performance and adaptability, remain the wisest choice.

The basic CR pump range is available in four different materials: cast iron, two grades of corrosion-resistant stainless steel, and all-titanium. There are 13 flow sizes, capable of producing up to 50 bar of pressure, and with a variety of shaft seals and rubber materials. The modular building system means you can choose a version to meet almost any pump requirement, handle difficult liquids and the most demanding operating conditions.

International studies* show that by far the most significant long-term energy savings can be made by optimising system design and control. Therefore, Grundfos iSOLUTIONS (intelligent solutions) philosophy takes a holistic view of systems and applications, rather than just supplying pumps. This means you are guaranteed an unparalleled level of service throughout the life cycle of the chosen solution.

Applications Multi-purpose CR pumps can be adapted to applications, ranging from simple domestic installations to heavy-duty industrial settings. These include: process water systems, hygienic washing and cleaning systems, seawater systems, water treatment, pumping of acids and alkalis, boiler feed, and applications involving temperature control with exposure to very high, low or fluctuating temperatures.

Whatever the particular challenges of your installation – for example, limited space, earthquake risk, high altitude or certification issues – the CR range has all bases covered.

Features and benefits

• Quality and reliability built on over four decades of continuous Grundfos testing and refinement
• Corrosion-resistant pump modules that can be combined in multiple ways to meet almost every conceivable requirement.
• Streamlined design to save space
• Grundfos MGE motor with integrated frequency converter to allow multi-speed operation and deliver optimal pump performance

The SEG range of grinder pumps from Grundfos is specifically designed for pumping effluent and untreated sewage in small communities or sparsely populated areas with no sewer systems or where gravitation systems are unsuitable.

Pressurised systems are the perfect choice for transfer of effluent and sewage, and the SEG range combines cost-effectiveness with maximum protection for the environment by facilitating the use of smaller pressure pipes for minimal investment costs.

The SEG range is designed to reduce energy consumption and to keep downtime costs to a minimum, while maintaining peak performance throughout the system life.

Applications

The Grundfos SEG pumps are specifically designed for pumping untreated wastewater from domestic, commercial or municipal sources. The high discharge pressure enables transfer of wastewater over longer distances.

Features and benefits

• Cable plug connection
• Efficient grinder system
• SmartTrim impeller adjustment
• Unique clamp connection
• Specially designed lifting handle
• Unique cartridge shaft seal
• Modular design
• Heavy-duty ball bearings.

Grundfos RC pumps are used for the circulation of liquid refrigerants in refrigeration systems.

The RC pumps have been designed and optimised for use with CO₂ as a refrigerant, but can also be used with NH₃ (Ammonia) and selected HFCs.

The low required NPSH and the fact that no traditional loss-generating protective devices are needed can help system designers to reduce the dimensions and cost of the system. The RC pumps have an innovative design in stainless steel which makes specially suited for use with high pressure refrigerants (CO₂) – the pump has only one seal between the refrigerant and ambient sides. A version with welded connections eliminates the use of counter flanges and possible leakage in flange connections.

Applications

Grundfos RC pumps are designed for the circulation of liquid refrigerant in refrigeration systems.

Features and benefits

• Barrel-type, semi-hermetic, high-pressure design
• Multistage centrifugal pump
• Canned motor (no shaft seals)
• High energy efficiency
• Wide range for variable speed capacity control
• Low NPSHR and robust to vapour bubbles in inlet
• Installation and service friendly
• Compact and low weight.

The Grundfos DW pumps are robust, portable submersible pumps with a vertical discharge port. Available with motors from 0.8 to 20 kW, they are designed to handle dewatering at construction sites, at excavation sites, in building drainage and in similar applications where there is a need to pump raw water or/and at high pressure. DW main parts are made of aluminium in order for them to be as light as possible. This factor, in combination with the compact design and the high-pressure capabilities, make DW pumps portable and easy to handle. The semi-open type impeller is made of high-chrome stainless steel (550HB) in order to increase wear resistance. DW.50.08 (only) has a polypropylene motor housing.

Applications

DW pumps are excellent for dewatering and draining jobs. The portable design, wear resistant parts and high pressure capabilities ensure the reliability, sustained performance, user-friendliness and ease of servicing that are necessary in demanding dewatering applications at sites such as:

• Construction sites
• Excavations
• Tunnels
• Steel works
• Fish ponds
• Underground parking drainage Industrial drainage pits.

Features and benefits

• Durability
• Portability
• User-friendliness
• Ease of servicing High pressure capabilities Control options.
