    Compact Dewatering Pumps

    Also known as bilge pumps, these remove fresh and salt water from spots where other pumps don’t fit. They have an internal sensor, so they turn on when they detect water and turn off when the water is removed. Pumps are fully submersible. They are gravity fed and require an elevated liquid source to fully fill the pump before turning on.

    Dual Float Switches for Sump Pumps

    Image of Product. Front orientation. Float Switches. Dual Float Switches for Sump Pumps.
    If the primary float fails, the backup float kicks in and an alarm sounds to indicate float malfunction. The floats are enclosed in a mounting cage to minimize false switch activation. Use these switches to replace an existing switch, or pair them with a plug-in activated pump that operates on 15 amps or less to control when the pump activates.

    Image of Product. Front orientation. Sump Pumps. Water-Powered Backup Sump Pumps for Water.
    Don’t let a power outage cause flooding. Powered by water flow in your supply line, this pump works as a backup to your primary sump pump. Use with debris-free water. Intake has a foot valve to prevent debris from entering your line. The water inlet has 3/4 NPT female threads and comes with a push-to-connect fitting for 3/4" ID tubing, so you can make either connection. The float switch is wired to the pump.

    Sump Pump

    Convenient for applications where a sump pit is impractical, this pump includes a basin with a vent on top. It has a float switch with a separate cord that can unplug, so you can replace the switch without replacing the whole pump. Also known as an effluent pump, it accommodates solids up to 3/4" in diameter. It is often used with liquid waste that has passed through a septic tank, so most solids are removed.

    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.
