Franklin Electric XS Series Close-Coupled Centrifugal Pump

What Is the Franklin Electric XS Series Close Coupled Centrifugal Pump?

The Franklin Electric XS Series Close Coupled Centrifugal Pump is a heavy-duty, high-performance pump engineered for demanding water transfer, irrigation, and industrial applications. Available at Ken’s Distributing, this pump is built around a close-coupled design that integrates the motor and pump end into a single compact unit, reducing footprint and simplifying installation compared to frame mount alternatives.

The Franklin Electric XS Series Close Coupled Centrifugal Pump was designed with three core priorities in mind: performance, serviceability, and long-term reliability. It features max-life bearings, enclosed hydraulically balanced cast iron impellers, back pullout volute design, and a choice of mechanical or packing seals to suit different application requirements. Available in 7.5 HP and 10 HP configurations, the XS Series is a serious workhorse pump built for applications where flow efficiency and durability are non-negotiable.

Kendisco carries the Franklin Electric XS Series lineup in both single-phase and three-phase configurations, with ODP motor enclosures available to match your installation environment. Whether you need a pump for irrigation, commercial water distribution, or industrial service, the XS Series delivers the performance and flexibility to handle it.

What Is a Close Coupled Centrifugal Pump?

A close coupled centrifugal pump is a pump design where the pump impeller is mounted directly onto the motor shaft, with the pump end and motor sharing a common frame. This design eliminates the need for a separate base plate, coupling, and alignment process that frame mount pumps require.

The benefits of a close coupled design include:

• Compact Footprint: The integrated motor and pump end take up significantly less space than equivalent frame mount configurations.
• Simplified Installation: No alignment between motor and pump shaft is needed, reducing installation time and the risk of misalignment issues.
• Easier Maintenance: The close coupled arrangement makes the pump easier to inspect and service in most installation environments.
• Lower Initial Cost: Fewer components means a lower overall cost compared to frame mount pump systems of equivalent capacity.

The Franklin Electric XS Series takes the close coupled concept further with its back pullout design, which allows the pump’s rotating element to be removed for servicing without disconnecting the suction or discharge piping. If you are not sure whether a close coupled or frame mount centrifugal pump is the right choice for your application, the team at Ken’s Distributing is happy to help you decide.
