When it comes to the working of a boat bilge pump, you should know that it is used for removing water from the bilge area of a vessel.

If your boat develops a leak, the bilge pump will kick in and remove any water collecting in the hull before it becomes a bigger problem.

So, if your boat is equipped with a bilge pump, it’s important to use it when needed.

One of the most common problems is that people don’t know how a boat bilge pump works and simply let water accumulate before finally using the pump.

Types of Bilge Pumps

There are three common types of bilge pumps: centrifugal, flexible impeller, and reciprocating.

Centrifugal Pump

Centrifugal pumps are the most common type of bilge pump. They work by using a spinning impeller to move water through the pump.

This type of pump is ideal for larger boats, as it can move a large volume of water quickly and efficiently.

One thing to keep in mind with centrifugal pumps is that they require a minimum amount of water in order to operate properly.

So, if your boat starts taking on too much water, the pump may not be able to keep up with the influx.

In order to keep your centrifugal pump in good condition, it’s important to clean the impeller regularly.

You can do this by removing the pump cover and rinsing off the impeller and surrounding area with fresh water.

Flexible Impeller Pump

The second type of bilge pump is the flexible impeller pump. This type of pump uses rubber blades to move the water. It’s usually used with a jet pump but can also be installed as a stand-alone bilge pump.

The main benefit of this type of bilge pump is that it can be used to move water through a horizontal, vertical, or angled pipe. It can also handle large amounts of debris without getting stopped up.

Since the impeller blades are made of rubber, they need to be replaced periodically. It’s also wise to keep an eye on the seals since they can wear down over time.

Reciprocating Pump

The third type of bilge pump is the reciprocating pump. This type of bilge pump uses a diaphragm or piston, which moves a rod back and forth to push water through the pump.

The main benefit of this type of bilge pump is that it can handle large debris, such as wood and furniture.

It can also handle large amounts of water without getting stopped up. Keep in mind that this type of bilge pump can become very noisy when in operation.

How Boat Bilge Pump Work?

Now that you know the different types of bilge pumps let’s look at how they work.

It’s important to know that most bilge pumps are electric. So, you’ll need to hook the pump up to shore power or a battery for it to work.

When water is detected, the switch inside the bilge pump automatically turns on, and electricity begins flowing to the pump’s motor. The impeller shaft begins to spin, and water is forced through the discharge hose and overboard.

For this process to work properly, you’ll need to set the pump switch on. This will ensure that it’s always active, even when the boat is sitting idle.

Bilge pumps have two switches in many cases: one for the pump and another for a high-water alarm. In this case, the alarm switch will automatically turn on when

the pump can’t keep up with the water entering the boat. This is an important safety feature, indicating that the bilge pump needs to be serviced.

Bilge pumps can also have a manual switch. In this case, the switch needs to be turned on when needed.

Understanding how a boat bilge pump works will ensure that it’s in good condition when you need it most. It will also help you keep your boat free of water in the case of an emergency.

Frequently Asked Questions on Bilge Pumps

Should I Leave the Bilge Pump On?

It’s recommended to leave the bilge pump on when the boat is in use. This will help ensure that the pump is always ready to go in an emergency. If you’re not using the boat, it’s best to turn off the pump to conserve energy.

Where Does the Bilge Pump Water Go?

The bilge pump water typically goes overboard through a discharge hose or directly into the ocean. It’s important to keep the area around the pump clear of debris to ensure efficient operation.

How Does Water Get into the Bilge of a Boat?

Water can get into the bilge of a boat in several ways. It can enter through the hull if there’s a leak, or it can come in through the vents and hatches. It can also come in through the drains, which are located on the boat’s floor.

What Happens If I Run My Bilge Pump Continuously?

If your bilge pump runs continuously, it will need to be serviced. This is especially true if your boat sits unused for long periods. If the bilge pump constantly runs with no water in the bilge, it may mean that there’s a problem with it.

Bilge pumps are an important part of any boat. They help remove water from the boat, keeping it afloat.

There are a few different types of bilge pumps available on the market today, and each one has its advantages and disadvantages.

If you’re looking for a new bilge pump for your boat, be sure to do your research so that you can find the best option for your needs.
