Floating water pump is a device used by fire brigades to refill their fire engine tanks from outdoor natural water sources. The pumps are also widely used in rescue and evacuation work, such as water transfer from flooded or obstructed areas. Due to their small size and combustion engine drive, these pumps can be operated even where there is no access to electrical energy.

Unlike other types of water pumps, a floating pump draws its water from a body of water via a suction pipe. Typically, this suction pipe has a mesh screen that filters out any particulates from the water. This is important because most tanks contain particulates that either settle at the bottom or float to the top, so a floating intake filter can ensure your pump always pulls from the cleanest area of the tank.

When the handle of a floating pump is pulled up, the piston moves down, creating downstroke. When the handle is released, the piston returns to its initial position, causing upstroke. This process is repeated over and over until the tank is emptied or the desired height is reached.

Some float pumps can be connected to a contactor coil, which enables them to operate when the contactor is activated. However, it is critical that you use a contactor coil with the right rating to handle the starting currents that the pump will demand when activated. If the contactor coil is not rated to handle the starting currents, it can damage the pump.
