Industrial boiler-feed and high-pressure steam systems can consider the Domestic 618PF-C35 Centriflo Series C35 pump with 10 HP power, 3,500 RPM high-speed operation, PF flange-mount close-coupled construction, and an approximately 6 to 7-inch nominal impeller.

The listed application requires careful review of boiler-feed conditions, fluid temperature, suction pressure, seal arrangement, and NPSH. Because the impeller diameter is approximate and the supplied record does not provide exact flow, head, pressure, temperature, or efficiency, final selection requires the applicable C35 curve.

Technical Specifications

- The 10 HP motor establishes the listed power class for boiler-room electrical planning.
- Operating at 3,500 RPM, the high-speed configuration affects curve and NPSH review.
- The PF flange-mount arrangement affects equipment attachment and installation layout.
- The close-coupled configuration combines pump and motor for replacement planning.
- An approximately 6 to 7-inch impeller range requires exact trim confirmation.
- Centriflo C35 construction identifies the pump family for technical-document review.
- Industrial boiler feed and high-pressure steam service define the stated application context.

Hydraulic Performance and Application

The C35 is listed for industrial boiler-feed and high-pressure steam systems, but the supplied record does not provide exact flow, head, NPSH, pressure, temperature, efficiency, or pump-curve values. The 3,500 RPM rating and approximate impeller range cannot establish hydraulic suitability without the required operating duty.

Installation Requirements

Confirm PF flange fitment, close-coupled mounting, motor electrical requirements, rotation, suction conditions, NPSH margin, seal compatibility, fluid temperature, pressure, and service clearance before commissioning. Boiler-feed installations require operating conditions and protective controls consistent with the applicable Domestic Pump technical and installation documentation.

Warranty and Maintenance

The supplied SKU information does not establish a named warranty duration, start date, coverage scope, or exclusions for this Domestic C35 configuration. Pump-curve, seal, suction-condition, and service requirements should be documented before purchase.
