• Carbon phenolic upthrust washer reduces wear in the pump hydraulics during heavy-use cycles, extending the service interval between maintenance events
• Built-in removable check valve on 10 to 20 GPM models prevents backflow through the pump when it cycles off, protecting both the pump and the distribution system from water hammer and reverse flow damage
• Available as complete submersible pump units or as pump ends only, giving contractors and system designers the flexibility to pair J-Class E-Series hydraulics with a separately sourced Franklin Electric submersible motor when replacing only the pump end

J-Class E-Series vs. FPS-E Series: Which Effluent Pump Do You Need?

Ken’s Distributing Company carries both the Franklin Electric J-Class E-Series and the FPS-E Series effluent pumps. Choosing between them comes down to your system flow rate requirements and head pressure needs.

If your effluent distribution system requires head pressure beyond what a standard single-stage pump can deliver, or if your drip field or spray system is located at a significantly higher elevation than the septic tank, the J-Class E-Series is likely the better choice. Contact Kendisco and our team at Ken’s Distributing Company will help you confirm the right pump for your system design.

Installation and Compatibility

The Franklin Electric J-Class E-Series Effluent Pump is designed for submersible installation inside a septic pump chamber, dosing tank, or wet well holding filtered effluent. The pump must be installed in treated, filtered effluent only. It is not rated for raw sewage, sludge, or heavily contaminated water with large solids.

Thermoplastic models are the standard choice for most residential septic effluent applications where mineral content in the water is moderate. Stainless steel models are recommended for installations where water chemistry is more aggressive or where longer service life between replacements is a priority.

The 10 GPM models are available in both 115 VAC and 230 VAC configurations to match the electrical service available at the pump chamber location. The 35 GPM stainless steel models are also available in both 115 VAC and 230 VAC. Confirm your available service voltage before ordering.

Pump end only models are available for both thermoplastic and stainless steel configurations, allowing installers to replace the hydraulic pump end while retaining a serviceable Franklin Electric submersible motor from a previous installation. This approach can reduce replacement costs significantly when the motor is still in good condition.

The built-in removable check valve on 10 to 20 GPM models simplifies installation in pressure dosing systems where backflow prevention is required. Larger models in the 35 GPM range do not include a built-in check valve and require a separate check valve installation in the discharge piping.

Motor lead length is 10 feet on standard models. Confirm that the 10 foot lead is sufficient for your pump chamber depth before ordering. Extensions and splice kits should be handled according to Franklin Electric installation guidelines to maintain motor warranty coverage.

Frequently Asked Questions About the Franklin Electric J-Class E-Series Effluent Pump

What is an effluent pump used for?

An effluent pump transfers clarified, filtered liquid from a septic tank, aerobic treatment unit, or dosing chamber to a secondary treatment or distribution system such as a drip irrigation field, spray system, or leach field. The Franklin Electric J-Class E-Series is designed for this role and is not intended for raw sewage, which contains large solids that would damage the pump hydraulics. If you need to pump raw sewage, Ken’s Distributing Company can help you select a grinder pump or sewage pump instead.

Can an effluent pump handle solids?

The Franklin Electric J-Class E-Series Effluent Pump is designed for filtered effluent containing only fine suspended solids that pass through a septic tank baffle or filter screen. It is not designed to handle raw sewage with toilet paper, wipes, or other large solids. Installing an effluent pump in a raw sewage environment will damage the pump hydraulics and void the warranty. For raw sewage applications, Kendisco recommends the Franklin Electric IGP Series Grinder Pump instead.

What is the difference between an effluent pump and a sewage pump?

An effluent pump handles clarified, filtered liquid that has already been partially treated by a septic tank or aerobic treatment unit. A sewage pump handles raw sewage including large solids and requires either a cutting mechanism (grinder pump) or a large solids passage design (sewage ejector). The J-Class E-Series is an effluent pump and operates after the initial septic treatment stage, not at the point of raw sewage collection.

What does J-Class mean in Franklin Electric pumps?

The J-Class designation in Franklin Electric’s pump lineup refers to the submersible motor platform used to power this series of pumps. The E-Series suffix identifies the pump as an effluent-rated product designed for treated water applications. Together, the J-Class E-Series combines the Franklin Electric submersible motor reliability with multi-stage hydraulic performance optimized for high-head effluent distribution in onsite wastewater systems.

How do I size an effluent pump for my septic system?

Sizing an effluent pump requires knowing the required flow rate in GPM, the total dynamic head in feet (including elevation change, pipe friction losses, and discharge pressure requirements), and the available electrical service voltage at the pump chamber. The J-Class E-Series 10 GPM thermoplastic models cover head requirements up to 619 feet at 1.5 HP and up to 242 feet at 1/2 HP. The 35 GPM stainless steel models cover up to 70 feet of head. Contact Ken’s Distributing Company with your system design parameters and our team will help you select the correct J-Class E-Series model for your installation.

Is the J-Class E-Series more efficient than the FPS-E Series?

Both the J-Class E-Series and the FPS-E Series are Franklin Electric effluent pumps designed for septic system applications. The J-Class E-Series uses a proven multi-stage hydraulic staging design with tight manufacturing tolerances that deliver greater pumping efficiency at high head conditions. For applications requiring very high head pressure over long distribution distances, the J-Class E-Series multi-stage design is generally more efficient than a single-stage pump trying to reach the same head. For standard residential applications with moderate head requirements, the FPS-E Series may be a more cost-effective choice. Kendisco carries both and our team can help you compare the two for your specific system design.

What septic applications use the J-Class E-Series pump?

The Franklin Electric J-Class E-Series is commonly used in pressure dosing systems for drip irrigation fields, high-head spray systems on elevated terrain, aerobic treatment unit effluent distribution, and ornamental or decorative water feature applications. It is also used in deep pump chamber installations where the significant drop pipe length requires a high shut off head rating that standard single-stage effluent pumps cannot achieve. Ken’s Distributing Company works with septic system designers and contractors on all of these application types.
