Volumes Pumped Per Cycle
•
The volume of fluid pumped per cycle from an AutoPump varies depending upon
the inlet air pressure, the fluid inlet head and the force against which the pump must
move the fluid. This force is a sum of the static head and dynamic losses incurred
during fluid movement, usually referred to as Total Head.
•
The Total Head 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.
