AP-2 Volumes Pumped Per Cycle
The volume of fluid pumped per cycle from an AutoPump® varies depending upon the inlet
air pressure and the total developed head (TDH) (static plus dynamic head). The closer the
pressures are to each other, (the TDH is almost the same as the inlet air pressure), the closer
the volume pumped per cycle will be to the lower end of the gallon range in the table below.
The TDH depends upon back pressure in the surface lines, hose size, fittings, vertical and
horizontal pumping distance, the number of pumps feeding the hose system, air pressure to the
pump, and the type of pump. The effects of some of these variables may cause the volume
pumped per cycle to vary from pump to pump on a single site.
Pump Volume per Cycle: Range
Long AP2 0.14 - 0.17 gal (0.53 - .64 L)
Short AP2 0.05 - 0.08 gal (0.19 - 0.30 L)
AP2 AutoPump Models
Volume per Cycle: Typical
0.155 gal (0.59 L)
0.065 gal (0.25 L)
