Lift & Distance Table Instructions

Pressure Compensating (15 GPM)

  1. The vertical lift is the elevation difference between the “off float” and the highest point in any zone.
  2. The diameter of the pipe from the pump tank to the hydraulic unit is 1 ½” minimum.
  3. All supply and return pipes are 1″.
  4. The flush return pipe from the hydraulic unit to the pretreatment tank is 1 ½” gravity.
  5. The maximum distance from the pump tank to the hydraulic unit is 30′.
  6. The tables may be used with the standard zone detail configuration only. A calculation sheet must be filled out for any other configuration.
  7. Top feed manifolds must be used when any discernible slope is encountered.
