Franklin Electric IGP Series Grinder Pump
The Franklin Electric IGP Series Grinder Pump is a residential sewage grinder pump that grinds solid waste into fine slurry and pumps it under pressure to a municipal sewer or septic system. At Ken’s Distributing Company, we stock the full IGP Series lineup including both manual and automatic models, available in single phase and three phase configurations. The IGP Series runs on a 2 HP motor at 3450 RPM, delivers up to 32 GPM at 20 feet of head, and achieves a precision cutting rate of 414,000 cuts per minute for reliable, continuous waste breakdown in residential and light commercial wastewater applications.
What Is the Franklin Electric IGP Series Grinder Pump?
The Franklin Electric IGP Series Grinder Pump is the core pump component used inside simplex grinder pump systems, duplex grinder pump systems, and PowerSewer grinder pump stations. It is designed for properties where gravity flow to the sewer is not possible. Instead of allowing sewage to flow downhill by gravity, the IGP grinder pump grinds all solids into a fine slurry and then forces that slurry uphill or over long distances through a small-diameter force main to reach the municipal sewer connection.
This makes the IGP Series the right solution for homes or light commercial buildings located below the sewer line, in low-lying areas, or at the end of a long sewer run. Kendisco supplies the IGP Series with full technical support and access to compatible control panels, capacitor kits, and retrofit components from Franklin Electric.

Applications and Industries
The Franklin Electric IGP Series Grinder Pump serves a wide range of residential and light commercial wastewater applications. Ken’s Distributing Company works with contractors, municipalities, and homeowners who rely on grinder pump systems for dependable sewage transfer in challenging site conditions.
- Residential homes below the gravity sewer line
- Properties located far from the municipal sewer main
- Homes in hilly or low-lying terrain where gravity flow is not possible
- Light commercial buildings requiring low-pressure sewer connections
- Simplex grinder pump station installations
- Duplex grinder pump station installations requiring a reliable pump component
- PowerSewer low-pressure sewer systems
- HOA and community sewer lift station upgrades
- Retrofit replacements for aging or failed grinder pumps
Features and Benefits of the IGP Series
- 2 HP motor at 3450 RPM delivers reliable power for continuous residential sewage grinding without overworking the system
- 414,000 cuts per minute precision cutting mechanism breaks down waste efficiently, reducing the risk of clogs or blockages in the force main
- Corrosion-resistant brass impeller with a seven-vane angled face design provides non-clogging, balanced hydraulic performance and reduces long-term maintenance costs
- Carbon/ceramic mechanical seal stands up to the demanding conditions of continuous wastewater contact
- Short, deflection-resistant motor shaft keeps the pump running smoothly even under high head conditions up to 130 feet
- Externally mounted start components make servicing the pump far easier without requiring full system disassembly
- Epoxy coated finish protects the pump body from corrosion in wet well environments
- Integrated overload protection automatically guards against over-current conditions and overheating, extending pump life

Installation and Compatibility
The Franklin Electric IGP Series Grinder Pump is designed for installation inside a grinder pump wet well or basin as part of a complete simplex or duplex grinder pump system. The 1-1/4 inch vertical FNPT discharge simplifies connection to standard force main piping used in low-pressure sewer systems.
The IGP Manual Series models require a compatible control panel or capacitor kit from Franklin Electric Pumping Systems. The control panel must be properly matched to the pump model and voltage for correct operation and to maintain third-party approval. The IGP Automatic Series models include an internal float or switch for automatic on/off operation.
Electrical requirements vary by model. Single phase models run on 208-230V service. Three phase models are available in 208-230V and 460V configurations. Always confirm your available electrical service before selecting a model.
Ken’s Distributing Company recommends pairing the IGP Series with compatible simplex or duplex grinder pump control panels available through Kendisco to ensure proper system operation, alarm function, and code compliance.
Lead lengths are available in 15 ft and 30 ft options depending on your wet well depth and installation requirements.

Frequently Asked Questions About the Franklin Electric IGP Series Grinder Pump
What does IGP stand for in Franklin Electric pumps?
IGP stands for Integrated Grinder Pump. It refers to Franklin Electric’s residential and light commercial sewage grinder pump series, which integrates the grinder cutting mechanism and pump motor into a single submersible unit designed for wet well installation.
How does a grinder pump work?
A grinder pump works by receiving raw sewage from the home or building into a wet well or basin. When the liquid reaches a set level, the pump activates and the precision cutting mechanism grinds all solids, including toilet paper, organic waste, and other material, into a fine slurry. The pump then forces that slurry under pressure through a small-diameter force main pipe to the municipal sewer connection or septic system.
What is the HP rating of the IGP Series?
The Franklin Electric IGP Series is a 2 HP grinder pump operating at 3450 RPM. It is available in 230V single phase and 230V or 460V three phase configurations to match different electrical service requirements.
Can I replace just the IGP grinder pump without replacing the entire system?
Yes. The Franklin Electric IGP Series is available as a standalone pump unit, which means you can replace the grinder pump component inside an existing simplex or duplex system without replacing the entire wet well, basin, or control panel. Kendisco stocks both the IGP-M Manual Series and IGP-A Automatic Series as individual units. Contact Ken’s Distributing Company to confirm compatibility with your existing system before ordering.
What is the difference between the IGP Manual and IGP Automatic models?
The IGP-M Manual Series requires an external control panel or capacitor kit to operate. The pump does not include an internal float switch and relies on external controls for on/off cycling. The IGP-A Automatic Series includes an internal float or automatic switch that activates the pump when the wet well reaches the set level, making it easier to use in systems where a full external panel is not required or already installed.
What is the maximum head pressure for the IGP Series?
The Franklin Electric IGP Series has a shut off head of 130 feet. At its peak flow rate, it delivers 32 GPM at 20 feet of head. Flow rate decreases as head pressure increases, reaching approximately 10 GPM at 120 feet of head. This performance range makes it suitable for most residential low-pressure sewer applications.
Does the IGP Series grinder pump need a control panel?
The IGP-M Manual Series requires a compatible Franklin Electric control panel or capacitor kit for proper operation. The IGP-A Automatic Series can operate with or without an external panel for basic on/off function. However, for full alarm capability, high-water warning, and code compliance in most municipalities, a dedicated simplex or duplex grinder pump control panel is strongly recommended. Kendisco carries compatible control panels for both simplex and duplex grinder pump systems.
