15 Delivery characteristic curves
This Chapter is intended to give you an idea of the delivery capacity that
the dosing pump can achieve at specific back pressures. These delivery
capacities were determined on the manufacturer's test stands. They ap-
ply at 20 °C (68 °F) for water, at 100 % stroke frequency. The delivery ca-
pacity depends on the medium (density and viscosity) and temperature.
Since these conditions vary at every installation location, you should cali-
brate the dosing pump.
