PUMPING PRODUCTION CHARTS
The amount of water which an SWT™ System will pump over a given period of time (usually measured in Gallons Or Liters Per Minute (GPM/LPM) or Per Hour (GPH/LPH) is based on the pressure
against which the unit has to work.
Pressure is determined by Total Vertical Pumping Distance referred to simply as "Head" or Total Dynamic Head "TDH". It is roughly equal to an increase of 1 PSI (Pound per Square Inch) for
every 2.31 Feet of TDH. Thus a vertical pumping distance of 231 feet (~70 Meters) equates to a pressure of 100 PSI.
Simply put, the greater vertical pumping distance, the less water which will be pumped.
Therefore, as the Charts below show, the greater TDH, the lower the GPH/LPH.

All Shown For Systems Using One Pump...
DOUBLING OR TRIPLING OF FLOW MAY BE OBTAINED BY ADDING A 2ND (up to 100'/30m) OR 3RD PUMP (up to 50'/15m)!!!
Maximum Pumping Depth:
SWT™ Systems utilize a Pressure Relief Valve which engages at 85 PSI. This added feature prevents damage which could be caused by excessive pressure build up from a constriction in the pipe
(e.g. if the pipe becomes clogged or livestock stands on the pipeline).
85 PSI equates to a depth of 196.3 feet (~ 60 meters). Therefore, when Total Vertical Pumping Distance begins to exceed 195 feet, pumping output will drop off as the Valve is engaged.
If you need to pump at Heads in excess of 200 feet, contact us for information about other water pumping options. We have systems suited to deeper wells (all the way up to 4500' / 1370 meters)!
