Every boat ends up with some unwanted water in the bilge, which is best removed as soon as possible to prevent damages, and ultimately prevent it from sinking. The last line of defense against unwanted water should in fact be also your first, and that’s bilge pumps. Boats usually come with a built-in bilge pump, but people often neglect them and they don’t get the love and care they deserve. Using a bilge pump to remove unwanted water is a much better solution than using a bucket, and I think we can all agree to that.
But what are bilge pumps, where do you get them and what are the things you should know before looking for the ideal bilge pump for sale for your boat? Well, as aforementioned, they’re considered the first and often time last line of defense against clearing nuisance water from bilges. And even though boats usually come with one that may be up to the job, however, an extra bilge pump can prove to be essential in critical times.
It can be the difference between soaking and standing afloat. It will give you enough time to potentially find the source of the leak or in more extreme cases, give you enough time to put on the life jacket and keep your boat afloat until help arrives. Most people look for an extra bilge pump for sale just as a safety means which provides extra dewatering capacity to your boat and already existing bilge pump.
When it comes to types of bilge pumps, they can either be diaphragm electrical and centrifugal. Centrifugal pumps relocate the water by using kinetic energy, using a solid, rotating impeller which is similar in design to a turbine. The water enters the pump, and the impeller speeds it up by rotating, and the water is forced up by the momentum it builds by itself. Centrifugal pumps are relatively inexpensive and don’t require much maintenance. Moreover, they’re capable of passing small amounts of debris without getting clogged.
On the other hand, diaphragm bilge pumps operate like little wet-vacuums. They suck out the water, which is pulled in through an intake valve, then is later pushed out through an output valve. They’re capable of pushing water better than centrifugal pumps vertically, and can be run dry without getting damaged.
Regardless of which type of bilge pump you decide to go for, make sure it has enough capacity. As a general rule of thumb, you’re looking for a pump that is rated at least 1.000 gallons per hour. However, if you own a larger boat that number should be higher. Generally, you want the biggest bilge pump your boat can accommodate.
