ANSI Pump Replacement Reduces Energy Costs of up to 50 Percent

The Multi-Stage CR-H provides the perfect solution for ANSI pump users seeking improved efficiency and increased life of their existing pumps. When traditional ANSI pumps are selected, they are often sized to maintain interchangeability within the plant. The result is often a choice that operates to the far left of the best efficiency point, compromising the long-term health of a pump. The ultimate in dimensional interchangeability: The unique design of the multi-stage CR-H offers optimized duty points to maximize pump efficiency and minimize internal wear, which significantly lowers energy costs, increases pump life and reduces maintenance. Increased system pressure demands on a traditional ANSI pump may require a complete pump replacement due to its single impeller diameter limitation, calling for expensive modifications to the pump foundation and piping. The CR-H allows for an expanded pressure range by adding additional stages and even the motor can be up-sized if necessary, all without piping or foundation changes. Reduced downtime ? seal changes in under an hour: Mechanical seal failures account for more than 75 percent of all pump failures. Besides parts and labor, production downtime can further increase costs associated with seal changes. In a traditional ANSI pump, the entire back pullout assembly must be removed from the baseplate and transported to a maintenance shop where the pump’s seal is replaced. This process can take several hours. The CRH cartridge seal can be replaced right on the spot without pump removal, disassembly, or pump-to-motor alignment, and be completed in as little as 30 minutes. E-Pump Option for even more energy savings: The Grundfos CR-H is also available with variable speed functionality, offering total control of the pumping system while providing maximum flexibility and as much as 80 percent reduction in energy costs. Other Applications: The Grundfos CR-H end suction pump is also available in ANSI dimensions and standard sizes for commercial building and irrigation applications.
