How does the bilge pump work?

The water entering the boat is discharged with the bilge pump, so it would be beneficial to have at least two bilge pumps in the boat. A small bilge pump may be required to drain the water that enters or spills into the boat, and in case of a potential problem, another bilge pump large enough to flood the boat may be required. Let’s explain the working principle of the bilge pump in a few items.
• The liquid descends to the pump, to the center of the impeller. After landing, the liquid flows out and enters between the blades of the propeller.
• The speed of the liquid increases due to the continuous rotation of the propeller.
• This velocity in the liquid enters the diffuser, where the kinetic energy of the liquid is converted into pressure. Pressurized liquid is then pumped out through the discharge.
• Thus, the wastes in the bilge are sucked by the bilge pump and taken to the compartments before they reach the pump.

How to connect an automatic bilge pump?

There is an automatic bilge pump as well as a manual bilge pump. A float-switch is used to automate the bilge pumps. When the water in the bilge rises, the float also rises with the water and affects the switch inside, thus enabling the pump to work. When the water level drops, the float also lowers and cuts the circuit. Thus, the operation of the pump is stopped.
How is the bilge pump operated?
Let’s summarize how the bilge pump is operated under a few items.
• Open the suction valve before starting the pump.
• Close the discharge valve while opening the intake valve.
• Be prepared to start the priming unit in the suction line and start the engine.
• Then slowly open and turn the relief valve.
• Adjust the flow amount via the suction valve.
• Before stopping the pump, stop the engine. Then close the discharge and suction valve.
