What Size Pool Pump Do I Need

A mutual question nosotros get from our customers is "What size pump do I demand for my pool?" As a full general rule, you lot should choose a puddle pump that filters all h2o in your puddle in an 8 60 minutes flow. It'southward important that y'all don't buy a pump bigger than your pool needs because it leads to higher operating costs and overpowering your filter system.

The standard hours a pool pump should accept for total water apportionment (turnover fourth dimension) varies. The following turnover times for residential pools are accepted in the pool manufacture:

• Indoor pools – 4 hours

• Outdoor pools – 6 hours

Stride one: CALCULATE THE NUMBER OF LITRES IN YOUR POOL

Here's an easy case of calculating your puddle volume:

Length 10 one thousand x Width 4 m x Average Depth ane.4 m = 56,000 litres

Step 2: Calculate THE Menstruation Rate

Flow rate how many litres the pump moves per minute (lpm). This is calculated using both the puddle's volume and turnover time.

Turnover time is the fourth dimension it takes for a volume of water equivalent to that of the pool contents to make i laissez passer through the circulation system.

The following turnover time is accustomed in the pool industry under residential pools.

- Indoor Pools - 4 hours

- Outdoor Pools - half dozen hours

And so permit's say you have an indoor 56,000 litres pool and a pump that has a turnover time of 4 hours, you can then work out the flow rate of your pump. For case:

Turnover fourth dimension = 4 hours 10 hr = 240 minutes

Period rate = Divide the book (56,000 litres) past the turnover time (240 minutes) = 230 litres per minute.

Stride three: Calculate THE TOTAL DYNAMIC HEAD

Now that we have the flow rate (230 lpm), we need to calculate the TDH (Full Dynamic Head) in metres to determine the performance of the pump needed to turn over the water. TDH refers to the total equivalent peak that fluid will be pumped by taking into consideration any friction losses in the pipe. Essentially "dynamic head" is the measurement of resistance working against your pool pump as it pulls water from your basin and pushes it dorsum to the pool. Most inground pools will be somewhere around fifteen metres TDH. Above ground pools typically fall effectually 9 metres TDH.

For example:

Caput Loss - Piping (chiliad) = 3.80 + Caput Loss - Valves & Fittings (m) = half-dozen.20 = ten Full Dynamic Head (m)

Now that you know the Total Dynamic Head (10 m) and the flow rate (230 lpm), you can apply this data to discover the size of pump you will demand to efficiently turn over your pool.

Footstep 4: REFER TO THE Flow CHART

By using the numbers we have calculated above (Period Rate 230 lpm and 10 m Full Dynamic Head) and this menses nautical chart, you will make it at the decision that CTX 280 pump would exist the suitable size.

Step v: FIND THE RIGHT SIZE FILTER

At present that you take found the appropriate pump size for your pool, you volition need to discover the correct pool filter size to lucifer. If nosotros continue with the CTX280 pump example, based on its input of 1070 W, we should select a 25" or 28" filter to go with information technology.

Come across below for other examples:

• 500 Due west goes with 20″ filter

• 750 W tin can go with 24″ filter

• 750 and 1100 Westward can become with 25 and 28″ filter

• 1100 and 1800 Due west can get with 28″ filter

• 1800 and 2000 W can become with 33″ filter
