Franklin Little Giant 20GPM High Head Effluent Pump

Franklin Electric Little Giant High-Head Effluent Pumps

The WE Series Franklin high-head effluent pumps far outperform the average effluent sump pump in terms of distance the water can be lifted (head), allowing them to be used in other applications requiring deep water or higher head performance such as aeration, water fountains, or other ornamental water features. Each septic system has unique requirements, so if your system has higher head effluent needs, look no further than Septic Tank Parts’ newest from the Little Giant WE Series! Other sizes are available, so contact a Customer Service Representative at 1 (800) 778-1540 to discuss options.

High-Efficiency Impeller

At the heart of the Little Giant beats an impeller, a propeller-like device, which is housed in a glass-filled PPO (polyphenol oxide) diffusor casing. The shape of this PPO staging area and impeller is fundamental in creating the centrifugal and other forces necessary for this multi-stage, vertical turbine pump to achieve the high-head lift of fluids. Made from materials that are especially suited for their anti-corrosive, chemical resistance, and ability to maintain their precise dimensions, the Little Giant high-head pump boasts a proven six-stage process that allows for exceptionally close tolerances resulting in enhanced operation and longevity.

Quality Construction

Quality is a top priority for us here at Septic Tank Parts, and a Franklin effluent pump offers that attention to detail.  Little Giant high-head submersible pumps are manufactured with a high-grade stainless steel motor housing, shaft, and fasteners; PEEK bearings; non-corrosive thermoplastic discharge and motor brackets; and a top-of-the-line Hex rubber top bearing with PEEK rubber, stainless-steel ball bearings, and increased surface area designed to divert suspended particles away from the bearing parts. This extra-large bearing also aids in shaft stabilization. Excellent design and superior parts throughout keep your septic tank pump running optimally.

Built-In Check Valve

The 20 GPM Little Giant septic pump comes complete with a built-in check valve that is easy to remove if needed. Check valves are an essential element to have as part of your septic tank effluent pump system. Built into the discharge pipe, check valves direct flow and keep liquids from returning into the tank/basin when the motor isn’t running. This prevents the effluent pump from pumping the fluid it has previously discharged - increasing efficiency and extending the motor’s life.

Effluent Pumps

Effluent pumps are submersible pumps that are commonly used in residential, commercial, and industrial septic systems to lift and transport filtered effluent (liquid waste) from a septic tank to a point of discharge – usually an absorption field, lagoon, or secondary vessel.

High-head submersible effluent pumps are most often used in aerobic spray or drip-irrigation septic systems. Unlike sewage pumps, which can handle larger solids, this type of septic tank pump requires filtration of the liquids prior to entering the unit. Depending on your system, treated effluent will travel to the pump chamber where some of the filtered solids will settle at the bottom of the tank. The Franklin mid-suction pump design brings in water through the center of the unit rather than the bottom (like an end-suction pump) allowing for additional filter screening to keep the pump damage-free and operating at peak performance.

Sizing Effluent Pumps

You may ask yourself “which is the best effluent pump for my system?” More than likely, the typical homeowner who is needing to replace their existing effluent pump will merely need to examine the model they have and find an appropriate equivalent, paying attention to A) the pump capacity measured in gallons per minute (GPM) and B) total dynamic head (TDH) measured in feet.

High-head effluent pump size is referred to in terms of pump capacity and head (lift distance). When looking at specs for your model it might look something like 26GPM at 50ft.

Detailed below are just a some of the elements that go into determining the capacity your effluent pump requires. Every system is unique and involve precise calculations so check with local building codes and the system designer so you can choose the correct septic tank effluent pump for your situation.

Professionals consider several factors when determining pump requirements:

• the type of system and its pressure requirements
• what size pipes are used
• the total vertical distance between the pump (at the intake point) and the highest elevation point in the system
• the total equivalent linear length of all the pipes and fittings

If you are concerned about your current pump capacity or have questions about your overall septic system needs, contact us at 1 (800) 778-1540 with your current pump’s make and model and we will help you find the proper solution.
