Page 12: Conveying Characteristics
Stepper motor-driven diaphragm dosing pump NXP-M and NXP-P Operating instructions 4.6 Conveying characteristics The design of the dosing pump enables it to perform the pressure and suction stroke at different speeds. For low supply rates, for example, the dosing pump performs the suction stroke at the maximum speed and adjusts the speed of the pressure stroke to match the desired supply rate. This produces a constant supply stream, which gives you a low-pulsation, smooth dosing. -
