Easy Flow Rate Guide for Sand Separator

Hello Marie,

Thank you for contacting us through our website.  You wrote:

We would recommend a centrifugal system such as the Sandmaster system listed below.  The sand separator works on a the principle of centrifugal force removing over 98% of all 200 mesh sized particles (74 microns) and greater. No moving parts to wear out, no screens, cartridges, cones or filter elements to clean or replace. The separator must be periodically purged, which is best done while the system is in operation and the water is flowing.  I’ve included a link to a common model as well as the automatic purging kit, as requested, so that you don’t need to manually purge the system.
I should point out that the Sandmaster system is sized based on the flow rate of your water, not the pipe size.  Do you know what your flow rate is?  If you are unsure of the flow rate, here are instructions on how to determine flow rate for wells with pressure tanks:


It is easy! All you need is a 1 or 5 gallon bucket and a watch or clock! It takes just a few minutes. Just follow these steps:

1. Open any hose bib or faucet until well pump turns on.
2. Close hose bib or faucet and let pump fill up pressure tank until well turns off.
3. Using a 1 or 5 gal. bucket, open faucet, collect and measure all water discharged until pump turns on. 
NOTE: You do not have to fill the buckets as fast as you can; simply measure the water.
4. When pump turns on, immediately close faucet and start timing pump cycle in seconds until well shuts off.5. Divide the number of gallons collected in Step 3 by the number of seconds in Step 4.
6. Multiply the answer from Step 5 by 60.
7. The answer in Step 6 is the average pumping capacity of the pump in gallons per minute (GPM).
