LF 3196 i-FRAME Low Flow ANSI Process Pumps

The LF 3196 i-FRAME is an ANSI chemical process pump purpose-built for low-flow, high-head services where a conventional pump would be forced to run far from its best operating point. Its concentric circular-volute casing and open radial-vane impeller keep operation stable and smooth even at heavily throttled flows, making it a dependable choice for continuous duty on small process streams.

Product Benefits

  • Lower radial loads: Running a standard end-suction pump at very low flow generates high radial loads that wear out bearings and seals prematurely. The circular volute reduces those loads dramatically compared with expanding-volute designs.
  • Longer bearing and seal life: Reduced radial loading translates directly into longer bearing and mechanical-seal life and fewer unplanned stops.
  • ANSI B73.1 standard: The pump is built to the ANSI B73.1 dimensional standard, so drop-in replacement is straightforward.
  • Interchangeable parts: Parts are shared with the widely used Goulds 3196, which makes spares easy to stock and keeps both installation and long-term ownership costs down.

Where It's Used

  • Continuous low-flow duty: The pump suits low-flow services that run continuously around the mill and plant on small process streams.
  • Mill and plant services: Typical duties include shower service, boiler feed, condensate handling, seal water supply, and hot oil circulation.
  • Specialty chemical duties: It is well matched to column reflux and reactor feed, where flow demands are modest but the required head is high.

Good to Know

  • Managed axial thrust: The open radial-vane impeller includes balance holes to manage axial thrust.
  • Enhanced seal environment: Enlarged TaperBore and BigBore seal chambers improve seal cooling and lubrication.
  • Hot-service option: An optional centerline-mounted casing keeps the pump aligned as temperatures climb.
  • Flange flexibility: Standard raised-face flanges can be upgraded to a higher pressure class, so confirm the flange rating and materials against your actual service conditions when selecting.
