How to Pick the Perfect Submersible Water Pump

Submersible water pump, as the name suggests, is a set of pumps designed to operate underwater. The motor is sealed to be airtight which blocks water from entering into it. They function well when fully submerged underwater. Their functional superiority makes them a popular type of pump and therefore, we have a high demand for the submersible water pumps. There are various subtypes of submersible water pumps available in the market, each with a distinct characteristic. It is often confusing to choose the specific pump type from the widely available range. This article throws light on various types of submersible pumps available in the market, distinguishing their unique features, hence, helping you make the right choice.

Benefits of Submersible Water Pumps

Before going further with the specificity of each type of submersible pumps available, it is important to discuss the benefits of this particular category as a whole. A submersible water pump's primary benefit is that it does not experience pump cavitation, i.e. it avoids air leakage in the pump. An added benefit for a deep-well pump application is that one doesn’t need to worry about priming the pump because the entire pump operates underwater. Submersible water pumps are also very efficient in working and unlike, the other pumps, they are not subject to the problem of overheating. Except for the permanent application submersible pumps like the pond-pump or the deep-well pump, submersible pumps are usually small in size, therefore, are easily portable and light-weighted. This makes them a convenient choice for usage in hard-to-reach places or smaller equipment like window wells.

Types of Submersible Water Pumps

As mentioned before, there are several types of submersible pumps available in the market. The section below explains the uses and applications for each type of submersible water pump available in the market.
Submersible Utility Pumps
The Submersible Utility Pump is best used for removing standing water, emptying clogged sinks or drain window wells. They come handy while solving problems of standing water. When choosing a utility pump, the most important factor to be considered is its portability. They are best used in smaller spaces where other water pumps just won't fit. The pump’s inlet size defines the total time required to pump out the water and discharge it elsewhere. A utility pump offers both manual and automatic configurations. The one with a float switch automatically turns the pump on and off according to the available water levels that limit the requirement of personal supervision. Urgent and semi-regular pumping applications are perfect for utility pumps. They work well as long as the water doesn't have debris or solids in it. One drawback of the utility pumps is that they can’t be used for cleaning dirty water, especially for sewage-type applications.
Submersible Trash Pumps
The Submersible Trash Pump is another type of portable pump. They are essential for removing dirty water quickly in small or large areas. Unlike other submersible pumps, the trash pumps have larger inlets and outlets, which makes them ideal for cleaning water with debris. They are easy to use, by simply attaching a hose and dropping it in standing water. But one needs to be careful for not dropping it in by the hose or the power cord. The trash pump uses a heavy-duty impeller, the centrifugal force shoots the water and debris out of the pump. These pumps are usually more expensive than the utility pumps. Because of the nature of the debris that the trash pumps can handle, they are usually rated for continuous duty and can easily pass sand, pebbles, leaves and more.
Pool Cover Pumps
Pool cover pumps are used to remove water and debris from pools (when not in use). They are pretty simple to use; just attach the hose, plug it in, and set on your pool cover and watch it go. These pumps are sometimes confused with utility pumps, which makes sense because utility pumps are sometimes used for removing water from pool covers, too.
Pond and Fountain Pumps
Fountain pumps and pond pumps both have some surprising uses. They can be used in aquariums, as well are great for filtering or powering waterfalls and small streams around your property. Some pond pumps come with a direct-drive dual discharge option, allowing one pump to serve two water features at once, which is easier than plumbing a separate pump for each feature. Fountain and pond pumps are usually quiet and rated for continuous duty, so they'll work for as long as they're plugged in. If you plan on using one for a pond with fish, make sure the pump is oil-free in design, otherwise, almost all are oil-less.
Submersible Deep Well Pumps
Deep Well Submersible Pumps enjoy all of the benefits listed earlier, plus have the benefit of coming with a built-in check valve to ensure system pressure and preventing backflow. Plus, because these pumps are sealed and used underwater, they are maintenance-free and are made with corrosion-resistant materials. Deep well pumps can be used in well-water applications from 15'-25' and excess of 500' in some situations, making them the best option for wells that are narrow or deep. But make sure to choose the proper pump size and the correct two or three-wiring option for the application.
