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

The Grundfos DP pumps are designed for pumping drain water and groundwater from installations in or around private housing, farms and small industrial plants. These pumps are also ideal for flood-relief applications and as utility pumps in farming, industry, etc.

DP pumps are fitted with a suction strainer, on which the pump stands. The suction strainer allows for the passage of solid particles of up to 10 mm in size, which is the maximum free passage size through DP pumps. The strainer is easy to dismantle for cleaning or for inspection of the pump hydraulics.

The impeller for the DP range is of a semi-open multivane design. The impeller clearance can easily be adjusted simply by tightening or loosening the adjustment screws at the bottom of the suction cover.

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.
