![]() Headquartered in Bergen, NY, Liberty Pumps is a leading U.S. With a vast offering of sump, sewage, effluent products Little Giant is the brand of choice to hundreds of thousands worldwide representing Franklin's commitment to quality, innovation, availability, and service. For over 70 years professionals in the water transfer market have trusted the Little Giant brand for its reliable pump solutions, packaged system options, accessories, and total value. Franlkin Electric has been recognized as the world's leading manufacturer of submersible electric motors since 1944. Little Giant is a division of Franklin Electric. They range from 4/10 HP all the way up to 2 HP. We carry sewage ejector pumps from Little Giant, Liberty, Zoeller, and Ashland. ![]() Our sewage ejector pumps can handle up to 2’’ solids and have either a 2’’ or 3’’ NPT discharge. These pumps are made for any low pressure, high volume pumping jobs. These pumps are designed to handle raw sewage wastewater, usually from a lift station in a basement or just outside of the house, to your septic tank or aerobic treatment system. Generally, if the numbers are relatively close, going to the next size larger unit is highly recommended.Sewage Ejector submersible pumps can handle raw sewage pumping jobs. The Total Dynamic Head that your pump must overcome has be lower than that shut off number in order for the pump to work correctly. The pumps are listed on our website as having a shut off at a certain feet of head. If you do not know the TDH for your application, our technicians will be able to calculate it for you simply knowing the vertical lift and the run distance. These two figures put together are what we call Total Dynamic Head (TDH). This number is figured by calculating the vertical lift (static head) along with pipe friction loss using the size of pipe, length of run, and flow rate of the pump. Head Pressure is simply the force that the pump must overcome to be able to push the water to its destination. If you can answer these questions, then choosing a submersible pump will be a piece of cake! HEAD PRESSURE EXPLAINED What kind of flow rates will the pump need to handle? (Roughly how many GPM do you expect to run through the pump at MAX capacity)? What kind of head pressure will the pump be pushing against? (The numbers you need to know is how high vertically the pump needs to push the water and the length of the horizontal run.) To make a decision on which size of effluent pump will work best for any certain application there are a few questions you will need to know the answer to: Effluent pumps can be used as sump pumps, but we would not recommend using a sump pump in an effluent pump application. Sump pumps are only designed to handle solids up to ¼’’ in diameter. This drainage water is typically clear and has little to no solids in it. Sump pumps are used to remove drainage water that has accumulated in a sump basin, commonly found in the basement or crawlspace of homes. Sewage ejector pump normally have a 2’’ or 3’’ discharge. They are designed to handle large solids up to 2’’ in diameter. These pumps are installed in a lift station that pumps raw sewage from a house or office to the septic tank or city sewer. ![]() Sewage Ejector Pumps are designed to handle raw sewage. Effluent pumps will normally have an 1-1/2’’ or 2’’ discharge. Because the septic tank or aerobic system has eliminated most of the solids, effluent pumps are only designed to handle small solids up to ¾’’ in diameter. ![]() These pumps are usually installed in a lift station after a septic tank or aerobic treatment system and will pump to a secondary treatment system such a drain field. EFFLUENT PUMPS - vs - SEWAGE EJECTOR PUMPS - vs - SUMP PUMPSĮffluent pumps are designed to handle treated wastewater with minimal solids. Submersible Effluent Pumps are designed to pump treated wastewater from a septic tank or aerobic treatment system to a drain field, sand filter, mound system, or any other type of secondary treatment system.
