Grundfos Expands Line of Multistage Centrifugal Pumps
New Material, Configuration and LiqTec™ Sensor Options Plus Reduced Energy Draw Provide Enhanced Flexibility, Reliability and Safety to CR Pump Line
Grundfos Multistage Centrifugal Pump CR5
OLATHE, Kans., April 12, 2002 – Grundfos today announced the expansion of its small multistage centrifugal pump line, with the introduction of the CR1s, CR1, CR3 and CR5 pumps, providing new sizes with greater flow range and enhanced to Grundfos’ industry-leading line of multistage pumps.
The new pumps will provide nominal flow rates from one half gallon per minute through 45 gallons per minute.
“No other supplier on the market today has a more competitive range of multistage centrifugal pumps than Grundfos,” said Greg Towsley, CR product manager for Grundfos. “In addition, our first-of-its-kind LiqTec™ Sensor, which automatically stops the pump when it detects an absence of liquid, reducing dry running as a risk to the units – answering one of the most common field use concerns about pumps of any kind.”
Responding to field user demands to simplify installation, the new pumps feature integrated shaft component cartridges, which insure proper assembly of the shaft seal and allow for seal replacement without dismantling the pump – reducing maintenance times from hours to minutes. In addition, the spring is pre-loaded precisely, to ensure the optimal tension between the respective seal surfaces. Cartridges are available in flushed seal, double seal and magnetic drive, operating in temperatures ranging from –40o F to +250o F.
The shaft seal and bearings are made from hard-wearing materials so that the CR can endure brief periods of dry running, which works in conjunction with LiqTec technology to increase reliability.
Reduced Energy Use Lowers Operation Cost
These pumps run on 10-30 percent less power than competing models, depending on the application, with the potential to save thousands of kilowatts per year.
“Combined with superior reliability and sophisticated motor technology, this energy savings makes the CR extremely competitive,” said Towsley.
Three material options are available for parts in contact with pumped liquid: stainless steel AISI 304/cast iron, stainless steel AISI 304 and stainless steel AISI 316. Special sizes and custom-built configurations provide high-temperature, low-NPSH performance in a variety of media, from drinking water or seawater to aggressive or high-viscosity liquids.
