About the Franklin Electric C1 Series Cistern Submersible Pumps Designed for use in gray water / filtered effluent service applications, the C1 Series cistern pump provides high performance and long life in less than ideal water conditions. The C1 Series pump is able to pass solids up to 1/8" without having a negative effect on the internal hydraulic components. The pump’s unique bottom suction design allows for maximum fluid drawdown without compromising durability or overall life, and it does not require the use of a flow induction sleeve. Intended specifically for use in a cistern or tank, C1 Series pumps are suitable for use in agricultural, residential, and commercial installations. Typical Applications of the C1 Series Pump Gray water pumping Cistern Tanks Aerator Tanks Well Pump Filtered effluent service water pumping Water reclamation projects such as pumping from rain catchment basins Aeration and other foundation or pond applications Agriculture and livestock water pumping Standard Features of the Franklin C1 Series Pumps Supplied with a removable 5" base for secure and reliable mounting Bottom suction design Robust thermoplastic discharge head design resists breakage during installation and operation Single shell housing design provides a compact unit while ensuring cool and quiet operation Hydraulic components molded from high quality engineered thermoplastics Optimized hydraulic design allows for increased performance and decreased power usage All metal components are made of high grade stainless steel for corrosion resistance Available with a high quality 115 V or 230 V, ½ hp motor Fluid flows of 10, 20, and 30 gpm, with a max shut-off pressure of over 100 psi Heavy duty 600 V 10 foot SJOOW jacketed lead
