Water supply on the boat -
To supply water on the boat, a number of water pumps are used and named according to their purpose and application.
Pressure water pumps
Fresh water pumps, pressurised water pumps & drinking water pumps supply fresh water on board. They are used to deliver the water from the tank to an outlet. Pressurised water pumps are located in the boat outside the water tanks. When they are switched on, water pressure in the pipes on board remains constant, so that the water reaches the outlet at full capacity.
In line pumps
In-line pumps are ideal for the drinking water systems on smaller vessels. One in-line pump is used to supply water for each fresh water tap. In-line pumps can be installed like valves in pipelines and are connected to the outlet with a hose and cable. In-line pumps are operated via microswitches on the water tap (tapping point). In-line pumps for small boats are characterised by their low power consumption.
Flushing pumps
Flushing pumps are used for toilets, for example. They draw in seawater for flushing and only activate when the toilet flush switch is pressed.
Shower water pumps
If used water, e.g. from the washroom, needs to be transferred to grey water tanks, it is best to buy a shower water bilge pump. Shower water bilge pumps in 12 V or 24 V from RM can be found in our range of fresh water pumps.
Double-port pump
Double-port pumps can be used, for example, to fill a tank (fish tank, ballast tank or similar) with seawater and at the same time wash the deck.
Water pressure systems / pressurised water systems
These systems are complete, compact pump systems featuring a pressure compensation tank, filter and other components. The compact systems are particularly suitable for boats with high water requirements.
These water pressure systems require various components to function correctly for them to be effective. Pressure compensation tanks, filters and other accessories can be found in our Website.
