Manual adjustment
The adjustment of the diaphragm stroke is
stepless and regular, and can be carried
out any time, i.e. when the pump stands
still or is running.

Theoretical flow rate
The theoretical flow rate corresponds
exactly to the volume displaced by
the diaphragm during its motion. Its
graphic representation is a diagonal
straight line whose progression is
determined by the diaphragm stroke
increasing(fig.3).
Actual flow rate
The actual flow rate is inevitably less
than the theoretical flow rate because
of the losses due to the reaction time
of the valves. The ratio between these
two flow rates determines the volume-
tric efficiency of the pump. The effi-
ciency depends on pump size, pump
head type (plunger or diaphragm),
liquid to be pumped, viscosity of the
liquid, working pressure, etc. (Fig.4)
