Is This the Right Septic Effluent Pump for My System?

The Franklin Electric E-Series 20FE05P4-2W115 is a 1/2 HP, 115V mid-suction submersible pump designed for filtered or treated effluent applications where higher pressure or longer pumping distances are required.

Common applications include:

  • Aerobic septic system spray irrigation
  • Septic sprinkler systems
  • Underground drip disposal systems
  • Mound systems
  • Long-distance treated-effluent pumping
  • High-head effluent applications
  • Filtered effluent service
Important: Do not select a replacement pump based on horsepower alone. Verify the required flow rate, total dynamic head, voltage, discharge size, control method, and treatment-system requirements before ordering.

If you are replacing an existing pump, send us the model number from the old pump or your system information and we can help you determine whether this Franklin E-Series pump is the appropriate replacement. Please Note: When replacing a pump, the pump float must also be replaced. We will not warranty these water pumps if the float is not purchased. 

Franklin Electric E-Series 1/2 HP Effluent Pump

The Franklin Electric E-Series 20FE05P4-2W115 is a high-head submersible pump designed to move treated effluent farther and against substantially more head pressure than a conventional sump-style effluent pump.

This makes it well suited for aerobic treatment systems that discharge to spray irrigation, drip irrigation, mound systems, or other pressure distribution applications.

The pump combines a proven Franklin Electric submersible motor with a four-stage hydraulic pump assembly. The staged design develops up to 152 feet of shutoff head while maintaining the performance needed for high-pressure treated-effluent applications.

Unlike bottom-suction sump-style pumps, the E-Series uses a mid-suction screened intake. It is intended for filtered or treated wastewater applications rather than pumping raw sewage or solids.

Key Features

  • High-head performance: Four-stage hydraulic design provides a maximum shutoff head of approximately 152 feet.
  • 20 GPM pump series: Designed for pressure-distribution applications requiring approximately 20 GPM class performance.
  • 1/2 HP Franklin Electric motor: Proven submersible motor designed for dependable wastewater and water pumping applications.
  • 115V operation: Single-phase, 2-wire configuration for common residential septic installations.
  • Mid-suction design: Screened intake helps keep larger debris from entering the pump.
  • Built-in check valve: The 20 GPM E-Series includes a removable integrated check valve.
  • Continuous-duty rated: Designed for demanding pumping applications when properly installed and operated.
  • Corrosion-resistant construction: Uses stainless steel and engineered thermoplastic components selected for water and treated-effluent service.
  • Dry-run-resistant shaft bearing: Franklin's 10 and 20 GPM E-Series pumps incorporate an engineered shaft bearing with built-in dry-run protection.

Important Pump Sizing Information

"20 GPM" identifies the pump's performance series and does not mean the pump will deliver exactly 20 GPM under every installation condition. Actual flow depends on total dynamic head, elevation, pipe size, pipe length, fittings, sprinkler or drip-system requirements, and other system conditions.

Shipping Information

Most in-stock orders placed before 2 PM Central Time ship the same business day.

Typical transit time is approximately 1–4 business days, depending on destination and carrier conditions.

Tracking information will be provided when your order ships.

Warranty Information

Franklin Electric lists the standard warranty period for this model as 12 months from installation or 24 months from the date of manufacture, subject to the manufacturer's warranty terms and conditions.

Replacement pump installations: When replacing an existing septic effluent pump, SepticStop requires replacement of the pump control float for warranty support. Contact us before ordering if you have questions about the correct float or control configuration for your system.

What is a mid-suction septic pump?

A mid-suction pump draws liquid through a screened intake located above the bottom of the pump assembly. This design is commonly used for treated or filtered effluent applications where the pump must generate substantially more pressure than a conventional sump-style effluent pump.

Can this pump be used with an aerobic septic sprinkler system?

Yes, this type of high-head effluent pump is commonly used to move treated wastewater from an aerobic treatment system to spray irrigation or sprinkler disposal systems. The pump must still be properly sized for the required flow and total dynamic head of the specific installation.

Can this pump be used for drip irrigation?

It can be used in properly designed treated-effluent drip systems where its performance matches the required operating pressure and flow. Filtration and pressure requirements vary significantly between drip systems, so confirm the system design before selecting the pump.

Does this pump have a built-in check valve?

Yes. Franklin Electric's 10 and 20 GPM E-Series pumps include a removable built-in check valve.

Can this pump handle raw sewage or solids?

No. This pump is intended for filtered or treated effluent. It is not a sewage solids-handling pump or grinder pump. Using the pump in an application containing excessive solids can damage the pump or restrict the intake screen.

Does a 20 GPM rating mean I will always get 20 GPM?

No. Pump flow changes with system pressure and total dynamic head. Elevation, pipe length and diameter, fittings, valves, sprinkler nozzles, filters, and other restrictions all affect actual flow. Pump selection should be based on the required operating point rather than the nominal GPM rating alone.

Can I replace another 1/2 HP septic pump with this one?

Possibly, but horsepower alone does not determine pump compatibility. Two 1/2 HP pumps can have very different flow and pressure curves. Confirm voltage, flow, total dynamic head, discharge connection, float controls, and treatment-system requirements before replacing another pump.

Not Sure Which Septic Pump You Need?

We can help you identify the correct replacement before you order. Have the model number from your existing pump, your system information, or a photo of the pump label available when you contact us.
