Overview
The FPS IGPH Series is Franklin Electric's dual-stage, high-head grinder pump for the toughest residential and commercial wastewater service: sewage lift stations, and low-pressure sewer systems for housing developments and lake communities where high vertical lift or long force mains are present.
Two brass impellers in series (dual-stage hydraulics) build the head. Ahead of them a cutting mechanism grinds solids at 414,000 cuts per minute. The 2 HP, 3450 RPM motor has built-in overload protection, a carbon/ceramic mechanical seal and a short, deflection-resistant shaft, in epoxy-coated cast iron.
The M in IGPH-M means manual: the start components are mounted outside the pump. Every IGPH-M runs from a control panel. Franklin states that IGPH and IGPHR single-phase pumps require the specific FPS control panel or capacitor kit matched to the pump for proper operation and third-party approval; three-phase models need an approved motor control with overloads. For a pump that starts on its own, choose the IGPH-A automatic series.
IGPH or IGPHR? Both are 2 HP dual-stage pumps. The IGPH is rated across its whole curve, from 40 GPM at 10 ft to 10 GPM at 175 ft. The IGPHR is rated only in the high-head region above the line Franklin marks at about 100 ft, and draws 16 FLA against the IGPH 18.5 FLA single-phase. Choose the IGPHR only where the total head stays above 100 ft.
Genuine Franklin Electric equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.
Warranty: 12 months from the date of purchase.
Growth & Multiplex
Runs as a simplex station, or as a duplex with two pumps alternating from a duplex grinder panel. The IGPH-M231 is the high-head option in the PowerSewer V4PS station.

Performance — Will It Do What You Need?
Find your total dynamic head across the top: the vertical lift from the basin to the highest point of the force main plus friction in the pipe. The figure below it is gallons per minute at that head.

Manufacturer tabulated points only. IGPHR models are rated only above the line Franklin marks on the curve at about 100 ft, so no IGPHR points are published below 100 ft; a dash means no rated point. Shut-off is the head at zero flow. Source: FPS Wastewater Catalog M5276 (09-25), IGPH-M spec sheet 996739 and IGPH-A spec sheet 996738.
The dual-stage IGPH keeps 30 GPM at 100 ft, where the single-stage IGP is down to 20 GPM, which is why Franklin specifies it for long force mains and high vertical lift.
