 All MasterFlo Pump Parts are interchangeable with Durco and Goulds ANSI Pumps

Master Flo Centrifugal Pumps (ANSI B73.1M) Hydraulics and dimensionally interchangeable with Durco MK III and Goulds 3196 Ansi Pumps. Upgraded power end is standard with oversized internally epoxy coated sump and laby or end faced bearing isolators.

  • All MasterFlo pump parts are interchangeable with Durco and Goulds ANSI pumps. OEM power ends and refurbished pumps are available.

Unique and versatile internal and external gear pumps.

  • Internal gear version utilizes design where both rotating parts are hydraulically balanced with no overhung loading. Process is fed from both sides of the gears and acts as an internal reducer slowing down the larger rotating gear resulting in reduced wear, less maintenance, compact size and less noise.
  •  Available in sealed and mag-drive configurations.

Complete range of water and chemical centrifugal pumps 

  • Single and Double Volute Multi-Stage split case pumps (up to 88,000 GPM & 3000' TDH)
  • Multi-Stage ring section pumps (up to 3000 GPM & 1800' TDH)


ANSI dimensional sealless,non-m​etallic centrifugal pump utilizing patented thrust bearing design

which eliminates the need for axial thrust bearings, creating a controlled internal environment which regulates the pressures on the process lubricated bearing.  This virtually eliminates the possibility of flashing while providing particulate control resulting in a "clean stream" to the bearings.  Available in various configurations up to 1100 gpm and 500'TDH.​

Offers a wide range of quality products and including the SICcast© slurry pumps.

  • SICcast © pumps provide the highest wear and corrosion resistance on the market today.
  •  SICcast© is a proprietary material developed by Duchting that is impervious to chlorides, and withstands pH values from <1 to 12.  SICcast© pumps also excel in small particle acidic slurries.
  •  Duchting also offers metallic slurry pumps and multi-stage ring section pumps.
