Boat Bilge Pump

Bilge pump, the most effective solution for drying your boat bilge

A bilge pump is the most effective way to remove accumulated water in your boat's bilge. It is one of the mandatory safety accessories on board according to article 240-2.15. From manual bilge pump to electric submersible bilge pump, each bilge pump has different advantages to best suit your use, and especially to eliminate water infiltrated into your boat. Several brands offer quality bilge pumps such as Attwood (a reference in the field), Whale supersub, Plastimo, etc. An Attwood bilge pump is a guarantee of quality for your boat, we present our Attwood bilge pumps below. You will find a wide selection of Attwood or Plastimo bilge pumps in our category dedicated to products dedicated to removing water from your boat. The other most popular brand is Rule. Rule is a specialist in bilge pumps and dewatering. The Rule store offers the best bilge pumps and dewatering accessories. Rule offers Rule automatic bilge pumps, Rule manual submersible bilge pumps, Rule automatic bilge pumps, and Rule high flow bilge pumps.

Without going into technical details, a bilge pump has a pumping system, membrane or centrifugal motor, and two hose connections. One hose is immersed in the bilge and allows water to be sucked in, the second allows water to be evacuated outside the boat. The flow rate varies depending on the power of the motor or the model of manual bilge pump chosen. Electric bilge pumps are waterproof and can be immersed in water without any problem. If you are dealing with bilge pumps produced by English-speaking companies, do not be surprised by the GPH unit of measurement. In the United States, Canada and the United Kingdom, the water flow pumped by a bilge pump is calculated in GPH, which represents the number of Gallons Pumped per Hour. A gallon represents 4.54 liters in the UK and Canada, and 3.78 liters in the United States. The GPH unit of volume is not widely used, but it is good to know what this GPH means.

Manual bilge pump

Unlike an automatic bilge pump, the manual bilge pump will need your physical action to operate and suck and evacuate water. Manual bilge pumps can be portable or not and evacuate between 25 and 100L/minute of water.

We offer the Plastimo Manual Diaphragm Bilge Pump , a manual bilge pump offering 8 positions of water suction pipes. This diaphragm bilge pump is made of resistant plastic and stainless steel for better resistance and reliability of water evacuation. The membrane of this bilge pump is removable. The Plastimo Manual Diaphragm Bilge Pump is a similar model but offering the choice between single and double effect. This bilge pump also offers a much better flow rate. This product is in stock at Nautisports. Free delivery from 150 euros of purchase.

For a recessed model with a telescopic handle, the Plastimo Pump 925 and 1038 Manual Bilge Pumps are two models with By-Pass possibility allowing to couple bilge pumps on the same circuit. Their flow rate of 0.9 L of water/cycle and 1L of water/cycle is quite high for a manual bilge pump. This product is in stock at Nautisports. Free delivery from 150 euros of purchase.

These bilge pumps are recommended for stagnant water or black water at the bottom of the bilge. Beyond that, they become too limited in terms of flow and cannot evacuate the water quickly enough. To evacuate a larger surplus of water, you will need to switch to an electric bilge pump. The ideal is to have one bilge pump of each in case an electrical problem arises, and thus be able to evacuate the water successfully in all situations.

Electric and automatic electric bilge pump

An electric bilge pump works with a motor pumping water from the bilge to send it out of the boat. This type of pump is fixed and is a submersible bilge pump waterproof. It is positioned at the bottom of the bilge without any problem, even in the most difficult corners thanks to their small size and thus works regardless of the amount of water present in the bilge. These are bilge pumps that do not require much electrical energy. The volume of water evacuated by this type of bilge pump is between 25 and 160 L of water/minutes.

There are two types of electric bilge pump:

  • The basic electric bilge pump. Electric bilge pumps have an ON/OFF switch to trigger the pump. This submersible electric bilge pump is very effective in evacuating water, but requires human action to trigger and activate the motor. It is possible to transform this type of pump into an automatic bilge pump thanks to the Attwood Automatic Bilge Pump Trigger . This waterproof electronic contactor allows you to do without the switch and automatically trigger your bilge pump submerged in water. The Tsunami MK2 Attwood Submersible Bilge Pump is an excellent submersible electric pump for a price of only 25€. This product is in stock at Nautisports. Free delivery from 150 euros of purchase.
  • The automatic electric bilge pump. This type of bilge pump is triggered automatically as soon as the bilge water reaches a certain level. A float is carried by the rising water until it makes contact when the water is at a high enough level, thus triggering the motor. The Sahara MK2 Attwood Automatic Bilge Pump is an excellent product of the genre. For a price of only 73€, you can acquire a compact and powerful automatic bilge pump. Its electronic contactor makes it an automatic bilge pump. This product is in stock at Nautisports. Free delivery from 150 euros of purchase.

These submersible electric bilge pumps with or without float contactor offer an excellent water evacuation flow rate through a pipe while remaining at affordable prices.
