Bilge Pumps

Use

Bilge pumps are used to remove excess water from the bilge of the boat or transfer liquids. They are necessary equipment in your boat as they free your hands from removing the excess water from the bilge and assist in maintaining your boat in good condition. Before you choose a pump, you should consider the size of the vessel, the quantity of water pumped and the discharge height. Please note that the higher the discharge height the harder the pump has to operate in order to push the water overboard.

Generally for 1m discharge height the following are suggested:

Boat < 6m => 600 Lt/h (Litres per hour)* for 1 m height

Boat > 6m => 900 Lt/h (Litres per hour)* for 1 m height

Boat > 6m => 1800 Lt/h (Litres per hour)* for 1 m height

* 1 Gallon (G) = 3.7854 Litres (Lt)

Instructions of Use

An important prerequisite for a normal operation of all electric devices is their connection to the main circuit. LALIZAS bilge pumps are connected serially to the main circuit and it is suggested that you use a 10A fuse. It is very important that you follow the wiring instructions when connecting the pump. The device can be mounted vertically to the hull, at a point where most of the excess water is found. The bilge pump may be activated either manually via a switch installed by you or automatically by a level switch (sold separately). There are also versions with a built in level switch.

Maintenance / Replacement

LALIZAS bilge pumps are constructed so as to operate efficiently even after long periods of time. However, for the best performance you should use and maintain them properly.

Therefore LALIZAS suggests the following:

- Use your bilge pump in combination with a level switch

- Place a 10A fuse on series with the main circuit

- Clean the bilge pump from any dirt

- Check regularly that everything operates correctly

- Avoid the use of any chemical substances in the bilge

ATTENTION: If you choose not to use a level switch you should supervise constantly the operation of the bilge pump and deactivate it when all the water is pumped, in order to avoid overheating it. Overheating the pump may affect negatively its operation and result in permanent damage.
