For a desired flow rate through the pump of 100 GPM,a minimum <br /> pipe size from the Chart 1 is selected at 3". At the desired flow of 100 GPM one cover could be partially blocked <br /> and the other suction outlet flow would be below the rated 125 GPM of the"Floor"mounted suction outlet cover. <br /> Since there are two outlets flowing in normal operation,and the allowable velocity in the interconnecting piping is <br /> only 3ft/sec,the same pipe size is required in the interconnecting piping. <br /> Example: In the System shown in Diagram 2, one(1)"Floor Only"suction outlet cover, rated at 125 GPM,and one(1) <br /> "Wall or Floor"suction outlet cover, rated at 72 GPM are selected and mounted. For a desired flow rate through the <br /> pump of 50 GPM, a minimum pipe size from the Chart 1 is selected at 2". At the desired flow of 50 GPM either <br /> cover could be totally blocked and the other suction outlet flow would be below the rated 72 GPM of the wall <br /> mounted suction outlet cover. Note: Flow may be limited by entrapping force in dual suction systems. <br /> Minimum distance 3 feet Dual Outlets on Different Planes <br /> (Pike Centerlines) Floor Outlets, (Elevation or Pian View) <br /> Total system rated <br /> flow 125 GPM Wall <br /> 72 GPM rated <br /> Total System rated <br /> flow 72 GPM Interconnecting <br /> Interconnecting piping <br /> piping c <br /> System branch piping <br /> System 125 GPM Rated <br /> Branch piping <br /> 24 Floor 4....
