    Float-Switch Activated Sump Pumps for Water with Small Solids

    Image of Product. Front orientation. Sump Pumps. Float-Switch Activated Sump Pumps for Water with Small Solids.
    Also known as effluent pumps, these accommodate solids up to 3/4” in diameter. They’re often used with liquid waste that has passed through a septic tank, so most solids are removed. The float switch is wired to the pump. All have an epoxy-coated cast iron housing that stands up to demanding environments. Submerge while in use and do not run dry.

    High-Flow Sump Pumps without Switch for Water with Small Solids

    Image of Product. Front orientation. Sump Pumps. High-Flow Sump Pumps without Switch for Water with Small Solids.
    Use these pumps to move higher volumes of water with solids than other sump pumps. They activate when plugged in; add a plug-in switch to control when the pump activates. Also known as effluent pumps, they accommodate solids up to 3/4" in diameter. They are often used with liquid waste that has passed through a septic tank, so most solids are removed. Pumps have an epoxy-coated cast iron housing that stands up to demanding environments. Submerge while in use and do not run dry.
    Wire Lead Connection—Pumps with wire leads can be connected to a three-blade plug or wired directly to a power source.

    Pressure Switches for Sump Pumps

    Image of Product. Front orientation. Pressure Switches. Pressure Switches for Sump Pumps.
    Since these switches activate on increasing pressure caused by rising water levels, they have no floats to catch on sump pit walls. Use them to replace an existing switch, or pair them with a plug-in activated pump to control when the pump activates.
    Wire Lead Connection—Switch with wire leads can be connected to a three-pronged plug or wired directly to a power source.

    Sump Pumps for Water with Small Solids with Replaceable Float Switch

    Image of Product. Front orientation. Sump Pumps. Sump Pumps for Water with Small Solids with Replaceable Float Switch.
    The float switch has a separate cord that can unplug, so you can replace the switch without replacing the whole pump. Also known as effluent pumps, these accommodate solids up to 3/4" in diameter. They’re often used with liquid waste that has passed through a septic tank, so most solids are removed. All have an epoxy-coated cast iron housing that stands up to demanding environments. Submerge while in use and do not run dry.
