D Series Close-Coupled Centrifugal Pump

Technical Product Description:

The Franklin Electric D Series Close-Coupled Centrifugal Pump is a rugged, motor-driven centrifugal pump designed for commercial, agricultural, and industrial liquid handling applications. The D Series is built with heavy-duty cast iron bodies for long-term durability and dependable service in demanding environments. Franklin Electric states the series is available in models ranging from 0.5 to 50 HP, making it a versatile solution for a broad range of transfer, circulation, and booster applications.  

A key feature of the D Series is its dynamically balanced impellers, which help reduce bearing loads and support longer pump life. This design contributes to smoother operation and improved equipment longevity under continuous or repeated-duty service.  

The pump is offered with both single-phase and three-phase motor options, along with TEFC and ODP motor enclosure configurations, allowing flexibility based on site conditions, electrical requirements, and application needs. Its close-coupled design also helps provide a more compact footprint and simplified installation compared to larger frame-mounted alternatives.  

With its durable cast iron construction, balanced hydraulic design, and broad horsepower range, the Franklin Electric D Series is well suited for users who need a reliable centrifugal pump for daily service across a wide variety of water handling and general fluid transfer systems.
