Piston diaphragm dosing pump
MEMDOS KMS LB/LA
Operating instructions
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 capac-
ities were determined on the manufacturer's test stands. They apply at 20 °C (68 °F) for water, at 100 % stroke frequency. The delivery capacity de-
pends on the medium (density and viscosity) and temperature. Since these conditions vary at every installation location, you should calibrate the dosing
pump.
