  2. Sump pump - Wikipedia

    en.wikipedia.org/wiki/Sump_pump

    Water-powered ejector pumps have a separate pump, float and check valve. [4] The float controlling a backup pump is mounted in the sump pit above the normal high water mark. Under normal conditions, the main electric powered sump pump will handle all the pumping duties. When water rises higher than normal for any reason, the backup float in the ...

  3. Float voltage - Wikipedia

    en.wikipedia.org/wiki/Float_voltage

    Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]

  4. Trickle charging - Wikipedia

    en.wikipedia.org/wiki/Trickle_charging

    [1] [2] A battery under continuous float voltage charging is said to be float-charging. [ 3 ] For lead–acid batteries under no-load float charging (such as in SLI batteries ), trickle charging happens naturally at the end-of-charge, when the lead–acid battery internal resistance to the charging current increases enough to reduce additional ...

  5. Float switch - Wikipedia

    en.wikipedia.org/wiki/Float_switch

    A pedestal sump pump with a float switch. A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.

  6. Franklin Electric - Wikipedia

    Franklin Electric Co., Inc. is a manufacturer and distributor of products and systems focused on the movement and management of water and energy. The company offers pumps, motors, drives, and controls for use in a variety of residential, commercial, agricultural, industrial, and municipal applications.

  7. Floating ground - Wikipedia

    en.wikipedia.org/wiki/Floating_ground

    Electrical equipment may be designed with a floating ground for one of several reasons. One is safety. For example, a low-voltage DC power supply, such as a mobile phone charger, is connected to the mains through a transformer of one type or another, and there is no direct electrical connection between the current return path on the low-voltage side and physical ground (earth).

  8. Hydraulic pump - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_pump

    They generate flow with enough power to overcome pressure induced by a load at the pump outlet. When a hydraulic pump operates, it creates a vacuum at the pump inlet, which forces liquid from the reservoir into the inlet line to the pump and by mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system.

  9. Nickel–cadmium battery - Wikipedia

    en.wikipedia.org/wiki/Nickel–cadmium_battery

    The charge rate is measured based on the percentage of the amp-hour capacity the battery is fed as a steady current over the duration of the charge. Regardless of the charge speed, more energy must be supplied to the battery than its actual capacity, to account for energy loss during charging, with faster charges being more efficient.
