Little Giant 9SN-CIA-RF (509204) is a 4/10HP, dual-mode (Automatic or Manual), Submersible Sewage Pump with a Remote Piggyback-type Float Switch and a 20ft long power cord. The piggyback remote float switch allows to regulate the On and Off levels for the automatic operation mode of the pump. When mounted on the pump (default install), the float switch has On level range of 9"-14" and Off level range of 2"-6". The 509204 model also features an oil-filled motor (lubricated for life), 2" high legs and a 2" FNPT discharge.

The 509204 model sewage pump is capable of handling spherical solids up to 2" in diameter and is commonly installed at the bottom of the sewage collection tank/basin. 2" legs integrated into the pump's design eliminate the need for a pedestal. The Little Giant 9SN-CIA-RF model is specifically designed to handle both sewage waste and wastewater (effluent waste) in residential and medium-size commercial and light industrial applications.

9SN-CIA-RF model sewage pump comes with an epoxy-coated cast iron housing & volume, as well as other composite and stainless steel non-corrosive parts to assure long-term integrity and uninterrupted performance.
