Pool Pump Gpm

All pool pump models will have charts with horsepower estimates based on flow rate ranges and total dynamic head.

Pool pump gpm.

The everbilt 1 5 hp pool pump is designed the everbilt 1 5 hp pool pump is designed for use with permanently installed above ground and in ground swimming pools. As an industry leader in pool and spa pumps we are proud to have designed smart and innovative pool and spa pumps that have earned the u s. For this example let s say you have a 20 000 gallon pool and the pool pump has a gpm rating of 40. It is constructed of corrosion resistant reinforced thermoplastic.

If the pool s turnover rate is higher than the filter s maximum gpm the filter is undersized and will not work properly. Now that we have gallons per minute gpm and pool volume we can calculate the run time. Efficient dependable and proven it has set the standard for excellence and value. Also available in our exclusive expert line addition as the super pump 700 which includes additional features such as an enhanced totally enclosed fan cooled motor design and top mount wiring compartment for easy installation.

Environmental protection agency s energy star designation by being at least 30 72 more energy efficient than others in the industry. If the filter is undersized it should be replaced or the pump should be undersized to prevent damage to the filter. The pool pump s gpm rating should be below the pool filter s maximum flow gpm rating. The 115 230 volt single phase motor is factory preset at 230 volts.

If a pool is 35 000 gallons and we want a turnover rate of 8 hours our equation would look like this. Pool volume in gallons turnover rate in minutes flow rate. Super pump is the world s best selling medium head pool pump. 35 000 8 60 73 gpm gallons per minute according to the table above we need a pump with a 73 gpm rating in order to achieve an 8 hour turnover time.

In our inground pool example we need a pool pump with a 20 8 43 gpm flow rate range and 50 tdh also called feet of head. Pool water flow rate is an important factor for determining turn over rate and ensuring the pool water is receiving adequate filtration. Flow rate is impacted by a number of variables like the dynamic head loss clogged skimmers clogged filters or addition of equipment like cleaners heaters and sanitization equipment that add to the dynamic head.
