The markedly lower electricity consumption of the new CR pumps increases your efficiency and makes the investment in a new pump worthwhile!
The new Grundfos CR series industrial pump offers the highest efficiency of any multi-stage centrifugal pumps in the world. A considerable advantage to the operating efficiency of large pumps.
The results are attributable to Grundfos' unique hydraulic design and the new production techniques. Servicing? It is rarely necessary. When it is, the process is straightforward and without the need for special tools. Complete Industrial Pump Specifications (up to 20 mins)

Seal Replacement Animation
The most serviced part of a pump is the shaft seal.
New CR shaft seals are easy, fast, and very simple to service without disassembly of the pump due to the Cartridge seal - and even without dismantling the motor (motor sizes > 10HP), a result of the Spacer Coupling design.
Shown: Correct preload of seal - and lifting of rotating stack - by the Adjustment Fork supplied with every pump.
Dry Run Protection Animation
The Hybrid shaft seal is capable of short periods of dry running - and yet being very wear resistant.
Runs on Tungsten Carbide/Tungsten Carbide surfaces when lubricated
Converts to Tungsten Carbide/Carbon impregnated Composite when heated up
