What Size Filter Do I Need For My Pool

A common question we get from our customers is "What size pump do I need for my puddle?" As a full general rule, you should choose a pool pump that filters all water in your puddle in an viii hr flow. Information technology'due south important that you don't purchase a pump bigger than your pool needs because it leads to higher operating costs and overpowering your filter organisation.

The standard hours a pool pump should take for total water apportionment (turnover time) varies. The following turnover times for residential pools are accepted in the puddle industry:

• Indoor pools – 4 hours

• Outdoor pools – 6 hours

Pace one: Summate THE NUMBER OF LITRES IN YOUR POOL

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

Length 10 grand ten Width four yard ten Average Depth 1.4 one thousand = 56,000 litres

Step 2: CALCULATE THE Menses RATE

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

Turnover time is the time information technology takes for a book of h2o equivalent to that of the pool contents to make one pass through the circulation system.

The following turnover fourth dimension is accepted in the puddle manufacture under residential pools.

- Indoor Pools - 4 hours

- Outdoor Pools - 6 hours

And then let's say you take an indoor 56,000 litres puddle and a pump that has a turnover time of 4 hours, y'all can then work out the catamenia rate of your pump. For instance:

Turnover fourth dimension = 4 hours 10 hour = 240 minutes

Flow charge per unit = Carve up the volume (56,000 litres) by the turnover time (240 minutes) = 230 litres per minute.

Step 3: Summate THE Total DYNAMIC Head

Now that we accept the menstruation rate (230 lpm), we demand to calculate the TDH (Total Dynamic Head) in metres to determine the functioning of the pump needed to turn over the water. TDH refers to the total equivalent top that fluid will be pumped past taking into consideration whatsoever friction losses in the pipe. Essentially "dynamic head" is the measurement of resistance working against your puddle pump as it pulls water from your basin and pushes information technology back to the pool. Most inground pools will be somewhere around xv metres TDH. In a higher place footing pools typically autumn around nine metres TDH.

For case:

Caput Loss - Pipe (m) = 3.fourscore + Caput Loss - Valves & Fittings (1000) = 6.20 = ten Total Dynamic Head (m)

Now that you know the Total Dynamic Head (10 m) and the menstruum charge per unit (230 lpm), you can use this information to notice the size of pump you will need to efficiently turn over your pool.

Pace 4: REFER TO THE Catamenia CHART

By using the numbers we have calculated above (Flow Rate 230 lpm and ten grand Total Dynamic Head) and this menstruum nautical chart, you lot volition make it at the decision that CTX 280 pump would be the suitable size.

Notation: Flow charts can be found in Resources > Brochure on the pool pump pages.

Step five: Notice THE RIGHT SIZE FILTER

Now that you have found the appropriate pump size for your pool, you will need to detect the correct pool filter size to match. If we continue with the CTX280 pump example, based on its input of 1070 W, we should select a 25" or 28" filter to get with it.

Come across below for other examples:

• 500 W goes with 20″ filter

• 750 W can go with 24″ filter

• 750 and 1100 W can go with 25 and 28″ filter

• 1100 and 1800 W tin can go with 28″ filter

• 1800 and 2000 Westward tin become with 33″ filter
