Bilge pumps and accessories
Bilge pump for the boat from a wide selection, including electric and manual pumps and all accessories for the pumps.

A bilge pump is an essential piece of equipment for boating that helps keep your boat dry and safe for you and your family. Without a bilge pump, water can accumulate in your boat's bilge from a variety of sources, including rain, wave splashes, and leaks. There are many different types of bilge pumps, so choose the model that best suits your boat's needs. You can find more information about bilge pumps and how to choose the right pump at the bottom of the page.
A bilge pump is a device that removes water from the bilge, or bottom, of a boat. While a small amount of water may not pose an immediate danger, the continued accumulation of water can lead to serious problems such as corrosion, damage to electrical systems, and even sinking of the boat.
The primary function of a bilge pump is to keep your boat dry. It works automatically or manually to remove excess water before problems arise. Without a functioning bilge pump, boaters can find themselves in dangerous situations in rapidly changing weather conditions or in the event of technical failures.
A well-functioning bilge pump extends the life of your boat and reduces the need for maintenance. Water accumulation can cause long-term damage to structures and components, so effective water drainage helps keep your vessel in good condition for longer.
Bilge pumps come in two main types: manual and automatic. Both have their own advantages and disadvantages, so making the right choice depends on the size of your boat, its intended use, and personal preference.
Manual bilge pumps are simple devices that are operated by hand. They do not require electricity or complex installations, and are therefore reliable, especially in emergency situations or when the power supply is uncertain. The main advantage of manual pumps is their simplicity and lack of maintenance - they do not contain any easily broken parts. However, using a manual bilge pump can be physically demanding and time-consuming, especially on larger boats or in situations where water accumulates quickly.
Electric or automatic bilge pumps, on the other hand, provide automatic water drainage without the need for constant user intervention. They can be either fully automatic, in which case they start automatically when the water reaches a certain level, or semi-automatic, in which case they are controlled by a switch. The main advantage of automatic pumps is their efficiency and ease of use – they can quickly remove large amounts of water without manual work. On the other hand, they require regular maintenance and a functioning electrical system to operate reliably.
On smaller boats, a manual bilge pump may be sufficient for basic use or as a backup pump in emergencies. On larger vessels, an electric, automatic bilge pump offers convenience and peace of mind, especially on longer voyages or in variable weather conditions.
The drainage capacity of a bilge pump is usually stated in gallons per hour (GPH) or liters per hour (LPH). Choosing the right capacity depends on several factors, including the size of the boat, its intended use, and how quickly water can accumulate in the bilge.
For smaller boats, a lower capacity, such as 500-1000 GPH, is often sufficient. This is sufficient to remove occasional amounts of water that may accumulate from rain or splashes. For larger boats, and especially for marine use, a higher capacity is needed – up to 2000-4000 GPH or more – to ensure rapid removal of water in the event of an emergency.
It is a good idea to consider factors that affect the efficiency of pumps, such as hose length and head. The longer the hose and higher the head, the harder the pump will have to work to move water out of the boat. It is also wise to consider installing a backup pump, especially for longer trips or more challenging conditions. The backup pump can be a smaller capacity manual pump or a second electric pump that operates through an independent system. You can watch a demonstration video of the Whale Supersub bilge pump here.
