Memdos Smart is a stepper-motor dosing pump for aggressive chemicals that can be operated as easily and reliably as a smartphone via its full-colour touch display. At the heart of the Memos Smart diaphragm dosing pumps is a drive with a microprocessor-controlled stepper motor. Unlike standard motors, however, the motor can be run asynchronously, meaning that the pump can operate at different speeds for the suction stroke and pressure stroke. This enables operation of the motor at a higher speed during suction, thereby creating negative pressure that draws in the fluid more quickly. After priming, the stepper motor can then operate at a slower speed to expel the fluid in a controlled and even manner without an abrupt increase in pressure. A slow mode is available for highly viscous media. The stepper motor enables an almost constant supply stream, which permits the gentle, low-pulsation dosing without pressure peaks and with minimised dead time. The Memdos Smart is available in eight performance levels, with delivery rates ranging from 2 l/h at a pressure of 20 bars up to 180 l/h at 4 bars. The pumps are designed very compact, e. g., the models with delivery rates of between 2 and 30 l/h are just 280 mm long, 130 mm wide and 220 mm high. The full-colour 3.5″ touch display can be integrated into the righthand, lefthand or rear side of the housing, depending on the version.
