Franklin Electric Effluent Pumps
- Choose the FPS E-Series, J-Class E-Series, or C1 Series cistern pump
- E-Series covers 10 to 90 GPM with shut-off head up to 619 feet
- Moves filtered effluent to drip, spray, and mound systems
- Thermoplastic or stainless steel builds with Franklin submersible motors
- 115 V and 230 V models for most pump chambers
- Send us your flow, head, and voltage and we will size it
The drip field sits up the hill, a long pipe run away from the septic tank, and gravity will not move the effluent there, so a Franklin Electric effluent pump has to. Which one depends on where the liquid comes from and where it has to go. This guide sorts the Franklin families by job and points you to the right models.
Match the Job to a Franklin Electric Effluent Pump
Every pump in this family is a submersible, multistage pump for filtered, treated liquid. They differ mainly in where the intake sits and how much flow and head they deliver.
| Your job | Franklin family | Why it fits |
|---|---|---|
| Septic dosing to a drip field | E-Series mid-suction (FPS or J-Class) | Up to 619 ft shut-off head on 10 GPM models |
| Aerobic unit to spray heads | E-Series mid-suction, 10 or 20 GPM | Dry-run protection and built-in check valve |
| Mound system or long force main | E-Series mid-suction, more stages | Multistage hydraulics built for distance |
| Higher flow dosing | E-Series stainless, 35 to 90 GPM | Ceramic sleeve and hex rubber bearings |
| Rainwater, gray water, or livestock tank | C1 Series bottom suction | Draws the tank low, passes 1/8 inch solids |
| Raw sewage before the septic tank | Not an effluent pump | Needs a grinder pump |
Filtered Effluent Submersible Pumps
All three Franklin models on this page belong to the filtered effluent family. Franklin builds them to pass the fine particulate that gets past a septic effluent filter, so they can run continuously in treated liquid.
The filter in front of the pump matters as much as the pump. Learn how the two work together on our filtered effluent pump page.
E-Series Mid-Suction Pumps: FPS and J-Class
What they are: multistage effluent pumps with the intake set partway up the body, above the chamber floor. The FPS and J-Class families share the same E-Series design and range.
Who they are for: septic installers and owners feeding drip lines, spray heads, mounds, and pressure dosing systems.
Standout specs: 10 to 90 GPM, 1/2 to 3 HP, and shut-off head from 65 to 619 feet. Thermoplastic 10 and 20 GPM models have dry-run protection. Stainless steel models cover 35 to 90 GPM.
See the model table on our mid-suction E-Series page.
C1 Series Bottom Suction Cistern Pumps
What they are: 1/2 HP submersibles that draw from the bottom of a tank with no flow induction sleeve.
Who they are for: rainwater harvesting, hauled water, gray water reuse, fountains, and livestock watering.
Standout specs: 10, 20, and 30 GPM models, shut-off head up to 225 feet, 115 V or 230 V, and a built-in removable check valve. Details live on the C1 cistern pump page.
Raw Sewage Goes to a Different Pump
Effluent pumps are built for liquid that has already passed through a septic tank. If your pump sits before the tank and sees toilet paper or wipes, choose one of our Franklin grinder pumps instead.

- Current pump: the model number from its label
- Dose rate: the GPM on your septic design or drip plan
- Total head: lift from the pump to the highest point, plus pipe length and size
- Voltage: 115 V or 230 V at the pump chamber
- Chamber depth: standard leads are 10 feet
More stages and more HP cost more, and stainless steel costs more than thermoplastic. Pump-end-only E-Series options cost less when your Franklin motor is still good.
Frequently Asked Questions
What is an effluent pump?
An effluent pump is a submersible pump that moves treated, filtered liquid from a septic tank, aerobic unit, or dosing chamber to a drain field, drip system, spray heads, or mound. It handles only fine particles, not raw sewage. Franklin Electric effluent pumps, like the FPS and J-Class E-Series, use multiple stages to build high head, so they can push effluent uphill or over long distances that a basic sump-style pump cannot reach.
What's the difference between an effluent pump and a sump pump?
The difference between an effluent pump and a sump pump is the liquid and the job. A sump pump removes clear groundwater from a basement pit, usually at low head. An effluent pump moves treated septic liquid to a disposal field, often at high head and long distance. Franklin's E-Series effluent pumps use multistage hydraulics and corrosion-resistant thermoplastic or stainless steel so they hold up in septic chambers where a sump pump would struggle.
What is the difference between a sewage ejector pump and an effluent pump?
The difference between a sewage ejector pump and an effluent pump is solids. A sewage ejector moves raw waste, including toilet paper and solids, from a basement bathroom or building to the sewer or septic tank. An effluent pump moves only filtered liquid that has already passed through the septic tank. Putting an effluent pump in raw sewage will clog or damage its stages. For raw waste, choose a grinder or sewage pump instead.
How long should an effluent pump last?
How long an effluent pump lasts depends on how clean the effluent is, how often the pump starts, and whether it ever runs dry. A clean effluent filter, correct float settings, and a pump sized to the system all extend service life. Franklin E-Series pumps help by using corrosion-resistant materials, and the 10 and 20 GPM models include built-in dry-run protection. Check the filter and floats whenever the tank is serviced.
