# A guide you need to buy a pool pump

The first step to choosing the right swimming pool pump is to know the volume of your swimming pool water. The formula is simple, long times multiplied by the height of water or p x l x t. Use the height of the water, not the height of the pool. Let’s say you have a pool size of 10 x 5 meters with a water height of 1.2 meters. So, the total water in your pool is 60 cubic water (10x5x1,2 = 60m3) If your pool is round, with a diameter of 10m and a depth of 1.2m. Then your pool water volume is 94.2 cubic (3.14×10 / 2 = 94.2m3). If your pool is oval, triangular or other antique shapes, then you need your grandchild’s help to calculate the volume of water. Meanwhile, don’t forget to check out the recommended Pool Pump for Above Ground Pools as well.

The flow rate is the ability of the pump to drain water within a certain period of time. For example, our P100 pump has a flow rate of 16 m3 / hr. That is, within one hour, this 1PK pump can siphon water as much as 16 cubics. If the volume of your pool is 60 m3, then a circulation takes 3 hours 45 minutes (60/16 = 3.75 hours)

If you use a larger pump, let’s just buy P200 with a flow rate of 30 m3 / hr. So to circulate all your pool water only takes 2 hours only (60/30 = 2 hours).

Before deciding to take home one of our pumps, it helps you to understand the optimal performance of pumps, pipe capacity, and design flow filters.

The maximum flow rate of P100 of 16 m3 / h can be achieved if there are no obstacles. Though the length of pipes, bends, and branching of pipes must exist. Not to mention the height factor, filter, dirt. Optimal performance of the pump should be at the 80% level. This will extend the life of the pump because it does not work.

The last thing you should know about flow rate is the capacity of sand filters. How much is your sand filter design? If it is too small there will be a bottle-neck in the filtering process.
