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
apply at 68 °F for water, at 100 % stroke frequency. The delivery capacity
depends on the medium (density and viscosity) and temperature. Since
these conditions vary at every installation location, you should calibrate
the dosing pump.
