Grundfos CR-Pumps

The basic pumps CR pumps range, which can be applied in almost any industrial solution, is already in itself the broadest range available. Through our modular approach, we have made it even broader.

The basic CR pumps range is available in four different materials: cast iron, two grades of stainless steel, and all-titanium. There are eleven flow sizes pumps, capable of producing up to almost 50 bar of pressure, and with a variety of shaft seals, rubber materials and supply voltages.

 

Grundfos CR Pumps

Pumps parts which are typically vulnerable to difficult liquids or particularly demanding operating conditions can be optimised for their purpose and designed for specific requirements.

 

Applications Pumps

CR pumps provide a complete range of pumps solutions so that all applications, industrial and domestic, can benefit from the Grundfos pumps touch. The applications that can be covered include the following:

  • Process water systems
  • Washing and cleaning systems
  • Seawater systems
  • Pumping of acids and alkalis
  • Ultrafiltration systems
  • Reverse osmosis systems
  • Swimming baths.

 

Features and benefits pumps

  • Reliability
  • High efficiency
  • Service-friendly
  • Space-saving
  • Suitable for slightly aggressive liquids
  • High corrosion resistance
  • Single-pump solution making high pressures possible.

Grundfos - Pumps

The durietta is a close-coupled, end-suction, single-stage or multistage centrifugal pump suitable for all kinds of low-flow, high-head applications requiring sanitary pumping equipment. The pump is designed in compliance with food technology requirements, making it ideal for applications where a high level of hygiene is required. It is CIP- and SIP-capable, and in line with the performance characteristics outlined for pumps in DIN 12462.
The durietta is made from high-quality stainless steel to ensure reliable, hygienic, non-corrosive operation. Stages, discharge and suction casings, and impellers are manufactured from deep-drawn rolled stainless steel.
