How Does a Bilge Pump Work?

To understand the type of bilge pump you need, you first need to understand how a bilge pump works. Here are some common points that describe the workings of a bilge pump:

• The liquid enters the pump through an opening at the center of the impeller (eye of the impeller).
• It then flows radially out to the impeller’s vanes.
• Due to the rotation, the liquid’s velocity increases.
• This high-velocity liquid enters the volute casing or diffuser, where the kinetic energy is converted into pressure.
• The pressurised liquid is pumped out through the pump discharge.

Larger crafts require larger bilge pumps to handle greater quantities of water. Refer to your craft’s manufacturer’s recommendations regarding bilge pumps or our guides for the appropriate size required. It is recommended to get a bilge pump with a greater capacity than the minimum suggested specifications.

Who Should Have Them and Why

Every boat owner should have a bilge pump because unwanted water can enter the bilge through leaks or the propeller shaft packing gland, and this water needs to be pumped out to prevent damage. Depending on the size of your boat, you need to choose the right bilge pump which not only suits your budget but also performs efficiently. If you have a small wooden boat, then even a manual bilge pump can do the job for you, while for larger boats, electric automatic bilge pumps are preferred. We offer many types of boat bilge pumps with various features and price ranges, so choose the best one for yourself now!
