Frame A/LD17 Centrifugal Pumps

The System One® Frame A and robust LD17 Centrifugal Pumps are pioneering process pumps with the built-in technology to get the most from seal and bearing life. Designed around the seal where 90% of pump failures occur, these centrifugal pumps have a stiffer, heavy-duty shaft and larger bearings resulting in the widest operational window off the Best Efficiency Point (BEP) than any standard process pump. These pumps come in 11 different sizes, meaning they are applicable for a wide range of fit scenarios and application needs.

The Frame A/LD17 has the stiffest shaft in the industry, which dramatically reduces seal and shaft failures. The Frame A/LD17 reaches flow capacities of 1,400 gpm (320 m3/hr) and is available in IPP metric construction.

Performance and Specifications

Five Year Power End Performance Assurance

Should any System One power end component fail within 5 years of the original installation, including bearings or shafts that have fractured, a free replacement component will be provided. This offer is limited to a claim for one of each component per power end.*

One Year Mechanical Seal Performance Assurance

Should any factory supplied and installed mechanical seal fail within one year after the sale of the pump and seal, a spare parts kit (with materials the same as the original seal) will be provided at no charge. Limit of one seal claim per application.*
