A pool pump is the most vital part of a well-functioning, clean, and safe swimming pool, no matter its size and type.
Since it has such an important function, it is essential to pick the best pool pump for your pool.
But given the wide variety of pumps being offered on the market, this could be a difficult task, especially for those of you who are new to swimming pool maintenance systems.
Read on to find out everything you need to know before choosing the best pump for your pool, including the different types of pool pumps, how they function, and the features to look for when buying one. You can also read the reviews of our top picks for the best pool pumps for 2020.
What are the main components of pool pumps?
Pumps for pools vary in size, shape, form, and features, but all of them have several main components that are essential for their functioning and efficient operation. Here they are:
The housing of a pool pump consists of a bucket and basket with a lid. The water from the pool is sucked into the bucket through the basket where the leaves and other debris are collected.
The inlet for water
This is the part through which the water from the pool enters the pump. The most important feature of the water inlet is its diameter. The larger it is – the bigger the maximum flow rate is.
The outlet for water
This is the part through which the water exits the water back into the pool.
This is among the most vital parts of the pump, as it captures and traps the debris from the water before it is released back into the pool.
This part of the pump is an inverted, fast-spinning blade, which helps propel and evacuate the filtered water from the pump back into the pool.
This is the engine of the pump, and it provides all the power needed to spin the impeller, which sucks in and then propels the water in and out of the pump.
The different pool pump speed options
Pool pumps come in different speed options. The speed of the pump is essential for the efficient filtering of the water in the pool. You should choose the speed type according to your pool size. Pumps with variable speed can be adjusted, so they are the best option, especially for larger pools.
Single-speed pool pumps
These are the most common and least expensive type of pumps for pools. The speed is only one, and is typically set to “high.” With single speed pumps, the impeller spins at the same speed at all times, and there is no way to adjust it.
Keep in mind that some states forbid the installation of new single-speed pumps (i.e., Arizona), so always check your local regulations before buying a new pool pump.
Dual speed pool pumps
These pumps have two speeds you can choose from – low and high. When set to high speed, the dual-speed pump functions much like a single-speed pump. But still, pumps of this type allow you to adjust the speed setting so that you can save energy. You can switch to lower speed during the peak usage hours to save considerable amounts of money for electrical bills.
Variable speed pumps
These pumps are powered by permanent magnetic motors (PMM). These are the best option of all types of pumps because of their efficient power saving features. They are usually the most expensive type too.
With a variable speed pump, you can adjust the speed as needed, and also can expect it to operate quieter than other pumps, as well as have higher durability than the simpler ones.
How to choose the correct flow rate of your pool pump?
Selecting the correct flow rate for a pool pump is key if you want the best results. The choice depends on your pool type and size. The flow rate of a pool pump refers to the time it takes for it to circulate all of the water in it, as well as the time it needs to dispense the chlorine to disinfect it properly.
The complete filtration cycle of your pool pump should last up to 6 hours, but if you want even better results, you may splurge out for a pump capable of filtering all of the water in your pool for less than 4 hours.
The horsepower and motor voltage
The more horsepower the pool pump has – the more powerful it is, and the faster it will circulate the water in the pool. Also, the less often it will need to run.
But keep in mind that you should pick the horsepower in accordance with the size of your pool filter and filtration system pipes. A pump that has too much horsepower can overwhelm a small pool filter. Also, one with too much horsepower will simply waste energy and money if your pool is too small for it. So, make sure you choose a pump with horsepower which can turn over the water in your pool at an adequate rate.
The pump can either need to be plugged in, or may need to be hardwired to your electrical system. Plus, pool pumps can run on 110 or on 220 volts, so you will need to check out the motor voltage and wiring before buying the best pump for your pool.
Choosing the right sized pool pump
If you want to buy an efficient pool pump, you should make sure that you pick one which can filter all of the water in the pool entirely at least once a day. This is the so-called turnover rate. Of course, it is better to opt for a pump which can turn over the water for 6 or even for less than 4 hours, but this depends on your specific needs and your budget as well.
In order to calculate the turnover rate of the pool pump you need, you should calculate the volume of your pool – or how much water it contains.
After calculating the volume, a rule of thumb is to divide the entire volume by 8 in order to establish the gallons per hour (GPH), which need to be pumped through the pool’s filter.
If the measure for the pool pump of your choice is gallons per minute, then simply divide the GPH by 60 to get the complete number of gallons per minute needed for completing a full turnover of the water in the pool.
The other features to keep in mind when shopping for the best pool pump
Apart from the size of your pool, which defines the speed, and the flow rate of the pool pump you need, other factors are essential for its efficient operation.
For example, if your swimming pool has a lot of bends in its pool piping, you may want to opt for a pump with a higher water flow rate.
Also, if you plan on installing the pump in a room or area which is at a significant distance from the pool itself, you will need to opt for a more powerful pool pump.
Plus, if the pump will need to push and propel the water upwards (vertically), then you will need to pick a more powerful pump too. You should consider the height of the pump in accordance with the skimmers for the best results.
Last but not least, you need to consider just how much work the filter will need to do before purchasing a pool pump. If your swimming pool requires a lot of maintenance, a lower-powered pump may get clogged and stop functioning. For pools that need serious filtering and maintenance, you should opt for a more robust pool pump.
How are above ground and in-ground pools different?
When shopping for a pump, you need to consider whether you will be shopping for a pump for an in-ground or an above ground pool. If you are planning to change the swimming pool type, you will need to change the location of the pump too.
For an above ground pool, you need a pool pump which is top-mounted and has intakes located above the ground as well. In case the pump and filter are at the same level, then you may want to opt for a side mount pool pump.
Pumps with DE or cartridge filters are usually side-mounted, while the sand filter pumps can work well when top-mounted and with top-mounted valves.
